Building A Low-energy House: The Steps

The state of the planet is worrying because of human behavior, and the high energy consumption is at the center of the debate. State provisions have been created to encourage the implementation of systems to reduce the energy consumption of each household. It is in this context that since 2012, the Low Energy Building (low-energy house) standard has come into force for the construction of new buildings. Here are the different steps to take to comply with this standard.

What is a low-energy house?

solar

A low-energy house is a new construction or a renovation respecting the Bâtiment Basse Consommation (low-energy house) standard. It is a house built to respect an annual energy consumption of 50 kWh/year. To reach such a level, it is recommended to insulate the walls and attics, airtightness, adoption of solar energy, and improvement of the ventilation system.

But the main objective remains the reduction of carbon emissions and the reduction of energy consumption. Since 2012, the low-energy house standard has become mandatory for new constructions. All real estate construction projects must take steps to acquire the low-energy house label.

The steps to take to comply with the low-energy house standard

Since the first bases for the construction of your house, some provisions must be taken into account.

Choosing the right building site

To have a low-energy house, it is important to choose the location of your land, especially its position in relation to the sun’s rays. The contribution of the sun’s energy is very important to meet the requirements of the low-energy house standard.

Vegetation is very important to having an ecological environment. The choice of land close to the basic essential infrastructures, namely schools and health centers, is favorably desired. You must also choose a plot of land on the ground and a basement in the least risky areas possible.

In addition, electricity, gas, telephone, sewage, and stormwater supply centers should not be far from you. This will save you a lot of money. However, it is strongly recommended to stay away from factories and power plants. As you can see, the quality of the immediate environment of your low-energy house is very important.

Ensure the feasibility of your project

home

This step is essential for the construction of your low-energy house. Go to the local town hall and make sure that the land is in a zone where construction is possible. The town hall will have to issue you with a positive urbanism certificate.

You should also consult the land use plan to make sure that your land is in a buildable zone. This is a large document that also defines the construction rules applicable in the zone.

Obtaining a building permit

The building permit is a very important document to start the construction of your low-energy house. Indeed, it is issued to you after a general inspection of your land on the basis of your construction plan. The administration then ensures that your construction respects the rules in force in the area.

The choice of the builder

home

This is the essential step in the construction of a low-energy house. You must then sign a construction and monitoring contract with this company to ensure the smooth running of activities on the site as well as a positive end to the work. This also gives you a ten-year warranty and insurance for damage to the work.

In conclusion, in the project of building a low-energy house, certain steps must be taken to ensure compliance with the procedure. Therefore, it is very important to know the steps to take during the development of your project. This article has given you all the information in this sense.

Electricity: An Indispensable Attribute In Our Daily Life

Electricity occupies a prominent place in today’s society. It is present in many areas of activity. In each area, electricity is used for various purposes. Given the usefulness of electricity in our lives, some people say that we could not live without it. If you are in that category of people who think otherwise, you are in the right place. Find out in this article how electricity is an indispensable attribute of our daily lives.

Electricity is used to light buildings

electricity

This is one of the reasons why electricity is indispensable to our daily lives. Indeed, electricity allows to light the buildings. Electricity companies have several electricians who are experienced in the task and who will put their know-how at your disposal. Note that it is necessary to contact an electricity company for any electricity-related work within a building.

You know that at nightfall, it is dark. The light provided by electricity through lamps allows people to go about their business. Indeed, some take advantage of it to read and others to work. This same lighting guarantees the safety of the inhabitants of a house. Thanks to the light, it is possible to see the thieves in the flagrante delicto.

Imagine a world without lights at night. It would be just awful. A day will end with the disappearance of daylight. It will have a huge impact on the economy. Many companies will go bankrupt. Indeed, companies will only be able to work during the day. Port handling will only be done during the day. Restaurants and bars will only be functional during the day.

Electricity promotes access to drinking water

electricity

Here is another reason why electricity is an indispensable attribute of our daily life. Indeed, electricity favors access to drinking water for the population. There is no doubt that you know water’s role in the human body. It is often said that water is life. Some studies have even proven that man cannot live long without hydration.

Electricity allows the world’s population to access this precious commodity, that is water. Indeed, drinking water is generally obtained by two methods. Either by dredging groundwater or by treating sea, lagoon, or river water. Both methods require the use of electricity-based equipment.

Once the water is ready for consumption, it is injected into the various local water networks. Thus, all the populations have access to drinking water. This is possible thanks to electricity. Here again, electricity-powered equipment is used.

Electricity drives industry

electricity

The fact that electricity drives industries are also a reason to make it an indispensable attribute. You may not have known it, but everything is industrialized these days. From the toothpaste you use to brush your teeth to the gadget you are reading this article with, everything is industrialized. Even the pillow you sleep on is industrialized.

Take a tour of the factories, and you’ll be amazed at the number of items that are produced every day. It’s really huge. To gain efficiency, these items are not produced by men. Instead, they are built by robots. These robots require electricity to operate. This is how factories work today.

You are no doubt aware of the importance of industry in the daily life of man. Indeed, if we move (cars, motorcycles, etc.) it is thanks to industries. If we eat (rice, spaghetti, etc.), it is thanks to industries. If we dress (shirt, jeans, etc.), it is thanks to industries. The factories being indispensable and running on electricity, the latter is also indispensable.

We will retain that electricity is indeed an indispensable attribute to our daily lives. Indeed, it is useful for several things like lighting, access to drinking water, etc.

Waste Recovery: Taking Care Of The Planet And Its Wallet

The safeguarding of the planet is nowadays at the heart of all discussions. Indeed, several actions are carried out in this direction by the leaders in the world. These actions have led to the creation of innovative techniques whose role is to ensure the protection of the planet. This is the case of waste recovery. If, like many, you do not know what is the recovery of waste and its usefulness, no need to worry. Discover in this article some answers.

What is waste recovery?

waste

The definition of this technique varies from one recycling specialist to another. Also known as waste reclamation, this technique is a set of processes aimed at transforming waste into another material usable by humans. Indeed, this waste can be changed into any type of material and energy product.

According to ADEME (Agency of Environment and Energy Management), the recovery of waste is subject to another definition. It considers a technique promoting the reuse and recycling of waste, reusable materials, and energy. For this agency, waste recovery is quite economical in raw materials and respects the environment.

The law that introduced waste recovery came into force on July 13, 1992. Since then, this method has been extremely successful. There are several reasons for this. The main one is that this method brings an added value to the waste by removing it from the collection and treatment circuits. Thus, the recovery of waste is totally opposed to its elimination.

What are the different types of waste recovery?

Over time, waste recovery has improved. Indeed, it knew some contributions and modifications. Today, this technique is declined in various forms. To be more precise, it exists under three types: material recovery, organic recovery, and energy recovery. In a few lines, here is a presentation of each of these varieties of waste recovery.

The material recovery

The material recovery takes into account partially or entirely a material (waste). This type of waste recovery inserts the said material into a new production process. For example, let’s take the example of used plastic bottles. These are melted down in order to be transformed into synthetic fibers. This waste is used for a different purpose.

Organic recovery

waste

Organic recovery is a technique that works in a slightly different way. Indeed, it uses two methods, composting and methanization. The waste is transformed into compost and is used to regenerate the soil. This waste can also be transformed into methane. Methane can be used as natural gas.

Energy recovery

Like organic recovery, energetic recovery has a particular way of working. In this case, the waste is incinerated in specially designed furnaces. The heat from this combustion is used to supply heating systems. It can even be used to supply electricity to homes.

What is the purpose of waste recovery?

As you can already imagine, waste recovery has many advantages. To begin with, it allows us to protect the environment and save the planet on which we live. Indeed, this technique allows reducing the quantity of waste present on earth considerably. Some studies estimate its reduction rate at 70%.

The recovery of waste allows us to save the planet; it guarantees better health to its inhabitants. This technique is also economical. It allows reducing the amount of fuel bills since it produces fuel. In summary, we can say that waste recovery is a beneficial technique on various levels. Indeed, it takes care of the planet and its wallet.

Thrift

waste

Second-hand does not have the bad image it had 20 years ago. The shame of wearing clothes already used by others is over, and this act has become trendy from a clothing point of view, ecological and political. Fed up with overconsumption, let’s change things!

You will find vintage stores everywhere that offer you nuggets at very (very) affordable prices. Go to second-hand bookstores, where you will find the latest Marc Levy, the first Balzac, and lost pockets that are just waiting for you to relive their stories. This is a trend that has been accelerated by the health crisis, as people are becoming more and more aware.

Spend an hour on online resale sites before going to the store to buy a new TV, there are probably people who are reselling theirs and will go buy another one, but with the one you’re taking back, that’s still one less in the garbage.

How To Get To A Waste Disposal Site In Paris?

Every year, millions of tons of waste are thrown away in the nature. The consequences on the environment are numerous and constitute a real danger for all. The waste collection centers are therefore proposed to recover and manage this waste. However, accessing a waste disposal center in the city of Paris can sometimes be very difficult. Here are a few tips to make your task easier.

Searching for and contacting the waste collection centers in Paris

waste

The first option to find a waste disposal center in Paris is, of course, the internet. All companies have a website these days. If you search for “waste disposal center Paris” in a search engine, you will see all the waste disposal centers in Paris that have a website. There are also some websites that provide information on the subject.

These list the waste collection centers in the city of Paris with their contact information, and you have to contact them. Searching on the internet is quick and easy, but it can also lead to false leads. There is often some information that is not available online.

There is nothing more than direct contact to clear up these probable grey areas. To do this, you can approach the Paris City Hall. The city hall is responsible for the cleanliness of the city of Paris. It is therefore in the best position to provide you with information. The city hall has a directory of all the waste disposal sites in the city. You can also ask people you know who have access to a waste disposal center.

Take into account the type of waste and the type of user

waste

There may be other constraints once you have found a waste disposal site. One of them is the type of waste you want to dispose of. Not all drop-off centers accept the same waste. There are several types of waste, and the waste collection centers only accept waste according to their capacity to either recycle or dispose of it. It is, therefore, not enough to approach a waste disposal center to have access to its service. It depends on the type of waste you produce.

Therefore, waste collection centers offer their services according to the type of user. Most private users have free access to waste collection centers. This is not the case for professionals. The waste collection centers implement a local community policy. They charge access to professionals, and private users contribute in turn through local taxation.

Take into account the distance between the construction site and the waste disposal center

waste

The other constraint that may arise after finding a waste disposal center in the distance. Paris is a big city, and waste disposal centers are often far from urban areas. Therefore, it can become a problem to get the waste to the waste disposal center if it is located at the other end of the city.

The solution to this problem is to prioritize the waste collection centers close to your construction site or your home. Waste disposal centers are not as popular as movie theaters; there may be some near you that you are not aware of. When searching on the internet or through direct contact, focus on your area. Fortunately, there are waste disposal facilities in almost every arrondissement in Paris.

All in all, accessing a waste disposal facility in the city of Paris can be a long process at times. But by following the tips mentioned and developed above, you should be able to do so more easily. Remember that waste management is everyone’s business.

How to Repair a Hydraulic Cylinder?

The hydraulic cylinder parts are quite sensitive and must be constantly maintained even if they do not fail. The hydraulic cylinder can be affected by various forms of failure that will result in either a replacement of the parts or just a repair. In each case, how to repair the hydraulic cylinder?

Failures related to the hydraulic cylinder

hydraulic

Hydraulic cylinders can be subject to different types of failures. The most common ones are:

  • Twisting of the rod
  • Leakage of the cylinder.

The torsion of the rod

At this level, two solutions are available between replacement and rectification of the positioning. The first solution will consist in replacing the twisted rod. If it is standard, we can order a new one from our supplier or think about a copy to be machined.

The second option is to see how far the positioning can be rectified. This is possible when the torsion is not important. The concept will require the use of parallel lathes and other heavy materials under the expertise of a professional. In both cases, most companies in this industry will be able to restore the machine.

A leaky cylinder

The most common failure related to the cylinder is the leak lets the liquid flow and can be internal or external. The external leak lets us see the liquid which flows. The former is much easier to repair, while the latter is more difficult to notice and detect.

In case of leakage caused by the wear of the cylindrical stem, it will be necessary to think of replacing it or trying to lapping or chrome plating it to smooth the damaged surface. If the seals are worn, the only solution is to replace them so that they can once again effectively inject the pressurized fluid into the hydraulic cylinders.

Routine maintenance check

If the hydraulic cylinder fails or not, a professional will proceed as follows:

Disassembly, rectification, and repair

hydraulic

After the external inspection of the cylinder, it should be disassembled to check each part. The parts are inspected separately to check the internal condition of the device. This dismantling allows for carefully cleaning each part, namely the cylinder, the rod, the ball joints, the seals, etc., and analyzing the origin of the failure if existing.

Replacement of the seals

Hydraulic seals wear out after a while of operation or may be damaged during the disassembly session for routine control. It is, therefore, better to replace these seals at each inspection to avoid possible surprising failures caused by them.

Checking the welds

Sometimes the leakage occurs due to the degradation of the weld. It will be necessary to proceed to grind to remake the tight weld. However, it is recommended to dismantle the cylinder before welding the affected part to avoid further damage. Even for ejection cylinders in molds, the principle remains the same.

What to do in case of scratches on the rod?

If the rod is scratched, there are two solutions. They are, of course, chroming and lapping.

1. Chrome plating of the stem

During the inspection, scratches or any other impact on the stem may occur. If the impact is not important, we can proceed to the matting and polishing of the concerned surface.

If the impact is significant, the rod must be replaced. If the problem is one of the repeated impacts, the specific materials used in construction equipment must be used for the repair.

2. Running-in of the shaft

hydraulic

The shaft can also be affected by scratches. In this case, to avoid a radical replacement, lapping with specific machines is necessary to eliminate the scratches and ensure the sealing of the hydraulic cylinder. For some machines, such as crushing machines, replacement may be expensive.

How To Fix Leaks In Industrial Facilities?

Industrial plants are often subject to leakage problems in fluid systems. A small leak that is neglected can become the source of a huge loss. Hence the reason to pay close attention and, in case of a leak, to work quickly to solve the leak. How do you manage these famous leaks?

Preliminary actions to be taken

leak

In order to solve a leak in an industrial installation, it is necessary to carry out some preliminary activities. These activities include

  • Detection of the origin of the leak
  • Prioritization of leaks
  • Resorption itself.

Detection of the leak

The detection will consist, first of all, of inspecting the possible fluid leaks thanks to a simple visual check. It can be liquid that oozes out or a plate formation on the floor. Bubble testing is another method of inspecting for possible leakage sources. This method involves the application of a surfactant to the fitting layers to see if bubbles are produced in the event of a leak.

Airborne ultrasonic testing is used on gas piping systems. It uses an airborne ultrasonic measuring device. The methods are innumerable and can be complementary when the leak is difficult to detect. All these tricks are better mastered and are the experts.

Prioritization of leaks

Prioritizing leaks means dealing with the most dangerous leaks before the least important ones. The team cannot deal with all leaks at once. Therefore, it is important to list them in order of importance. Leaks that are considered dangerous are acid leaks and leaks of harmful and accident-prone gases. These leaks should be repaired as a priority.

Solutions to leaks in industrial facilities

leak

After the preliminary actions, the repair can be started according to the different possible solutions. This is the actual repair of the leakage problem.

A leak in a fitting

In case of a leak on a fitting, an anti-leak tape is needed. Simply roll the tape in a spiral, covering half of the previous layer with each turn. The tape should extend 5 cm beyond the exact location of the leak. This technique is most effective when the leak is in a pipe or in a defective weld.

It is true that the nature of the intervention will depend in part on the different types of industries that have recorded the leaks concerned, but home-made tricks are not negligible. In this situation, the leak can also be sealed with leak-proof sealant. This product is very appreciated for its resistance to high temperatures. It works on many materials, as does the anti-leak tape.

A copper pipe leak

With a copper pipe, sealing is fairly simple and involves two possibilities. The first possibility is to seal the leak with rubber and a hose clamp. The second possibility is to use a piece of soft plastic instead of rubber at the leak and try to hold it in place with the clamp.

What to do after the emergency intervention?

leak

To avoid possible occupational hazards, most of the work should be done by experts. The methods available to everyone will only serve to delay damage and save fluid. If you are not experienced, there is a greater risk of aggravating the leak.

The installations must be well done so that they remain watertight for a very long time. It will still be necessary to choose the right expert in repairing various leakage problems in industrial facilities. This applies right from the selection of the industrial building construction professional in question.

Top 4 Things Everyone Should Know About Solar Panels

We only have one planet, and we need to start acting as such by adopting a more eco-friendly way of life. This is buying solar panels and installing them on your own is environmentally friendly and is good for the environment. This is a win-win situation if you ask us. So, without further ado, let’s dive into this blog and learn more about solar panels.

1. How do solar panels work? 

solar

This is one of the first questions you might ask yourself if you want to invest in a photovoltaic system. A photovoltaic system consists of the following elements:

  • Solar panels, which are themselves made up of photovoltaic cells
  • A fixing system
  • A charge controller
  • An inverter that allows the transformation of direct current into alternating current
  • Wiring
  • A production meter
  • A consumption meter
  • A supervision system
  • A circuit breaker.

The photovoltaic cell is the centerpiece of a photovoltaic system. The modules are made of these cells and then assembled into panels. Silicon is the material that allows the photovoltaic effect to occur. It is a semi-conductor compound that creates an electric current when in contact with sunlight. To be more precise, a cell is composed of two layers of silicon, one positively charged and the other negatively, like an electric battery.

The sun’s rays, and more specifically the photons, pass through the photovoltaic cell. They create a hole in the upper (negative) layer and generate an electrical voltage with the lower (positive) layer. The generated current is transformed into alternating current thanks to the inverter in order to supply the equipment of a house or a building.

2. Price

Since electricity tariffs are constantly increasing and feed-in tariffs are decreasing, connections to the grid for total sale installations are likely to decrease to the benefit of self-consumption photovoltaic connections.

Until 2017, individuals who would integrate solar panels into their roofs benefited from a better feed-in tariff for their electricity. The price per kWh was set at 0.46$ for installations with 9 kWh or less power. Thus, the feed-in tariff of electricity has decreased by 65%. 

 Many households make a choice to make the total sale of their electricity. Depending on your consumption habits, the characteristics of your roof, or your budget, this solution can be more profitable for you if you are in a lucrative and eco-responsible approach. 

3. Return on investment

solar

The price of a solar panel installation is often one of the main reasons for the reluctance to take the plunge into photovoltaics. However, the profitability of an installation is no longer in question. The fall in prices in photovoltaics and the increase in electricity tariffs make photovoltaics and, in particular, self-consumption more and more interesting financially.

An installation costs between 2,200 and 2,800 dollars per kWp and generates significant reductions in electricity bills each year. Either directly through self-consumption or indirectly through the sale of the production to an electricity supplier.

State aid for the installation of photovoltaic panels, such as the self-consumption bonus or the EDF OA feed-in tariffs fixed over 20 years, further improve the profitability of solar panels. Depending on the geographical area and the solar installation cost, the return on investment is reached between 10 and 15 years.

4. A civic gesture 

Today, it is difficult for government representatives to adopt (at least publicly) a position that would not be favorable to the energy transition in the United States. Nuclear power is the object of all the wrath; renewable energies have the wind in their sails. In 2020, they will account for 19.1% of the US’s gross final energy consumption, of which 3.4% will be produced by photovoltaic solar energy.

The 2015 law on energy transition for green growth aims to raise the percentage of renewable energy in the US energy mix to 32% by 2030, which is 5% higher than the European aspirations for the same date. Thus, by installing solar panels on your house, beyond your personal convictions, you are taking a resolutely civic approach through your contribution to greening the US public electricity network.

Sprayed Polyurethane: An Innovative And High-performance Material

Sprayed polyurethane is one of the most widely used materials in home insulation. Indeed, its performance makes it the perfect element to protect a house against heat loss. Definition, functioning, price, advantages… A point on sprayed polyurethane. So, without further ado, let’s dive into this blog and learn more about sprayed polyurethane.

What is sprayed insulation?

insulation

Whether to save energy or to preserve the environment, thermal regulations are always demanding. Therefore, thermal insulation experts have developed a more efficient method to obtain a better result: sprayed insulation. Nowadays, it is considered the best thermal insulation solution used in renovation or construction. This is a kind of illustration of the technical progress that is made in this field.

Sprayed polyurethane: for what purpose?

In the past, polyurethane foam was only used for the insulation of woodwork. But nowadays, it is also used to eliminate heat loss from roofs, floors, walls, and attics. Indeed, sprayed polyurethane is an ecological insulator that hardens easily after use. This is possible due to the chemical reaction between isocyanate and polyol.

How to apply spray polyurethane foam?

Polyurethane foam must be applied to a dry and clean surface. This operation must be carried out by an authorized specialist, such as Isol’o2, and established in Avignon. This company carries out all building insulation work.

The projection is generally made with a hydraulic or pneumatic pressure gun. The person in charge of projecting the polyurethane foam propels it in semi-liquid form over the area to be insulated. This insulation will then expand and swell when it comes into contact with air. This allows it to reach more than 30 times its volume before solidifying. The homeowner can then decide whether or not to cover it with a finish.

What is the energy performance of spray polyurethane?

insulation

Polyurethane foam has a specific expansion capacity that allows it to cover all the most minor gaps in the insulated element. In fact, it is able to reduce a large part of the thermal points.

The sprayed polyurethane also has technical properties allowing it to be a thin insulator. To insulate a floor or a wall, it is enough to apply a superficial layer of 6 cm of sprayed polyurethane foam. But for a more excellent thermal resistance, it is advisable to apply a layer of more than 12 cm for the insulation of walls and attics.

What are the advantages of sprayed polyurethane?

There are many advantages to the application of sprayed polyurethane foam:

  • It fits into all the areas to be insulated to form a perfectly homogeneous and airtight envelope.
  • Unlike other types of insulation, sprayed polyurethane does not emit toxic products that can irritate the respiratory tract.
  • Polyurethane foam is very resistant and has an unlimited life span.
  • Sprayed polyurethane is lighter than other insulations. It can therefore be applied to all types of housing structures.
  • Since the foam is manufactured on-site, it does not incur high transportation costs.
  • This insulation also reduces the energy bill.
  • This recyclable material also limits rodent and pest infestations.

Spray polyurethane foam: at what price?

insulation

In general, the budget required for sprayed insulation depends on the type of home and the professional contact. Before choosing the craftsman, it is strongly advised to ask for several comparative estimates. In any case, count between 6 to 10 dollars per square meter for a floor insulation. Expect to pay between 15 and 25 dollars per square meter for roof and wall insulation.

Cellulose Wadding: An Ecological Insulation

In terms of ecological insulation, cellulose wadding is very popular. It has intrinsic qualities to improve and maintain a house’s thermal and phonic comfort. To learn more about this type of insulation, read the following article!

Composition

insulation

Often known as “cellulose insulation”, cellulose wadding is composed of :

  • 15% minerals
  • 85% recycled newspapers or cardboard: the coated paper should be avoided. Indeed, it is too crushed to insulate and trap air. In order to provide excellent insulating performance, the paper or cardboard is mixed with additives during shredding.

Ammonium polyphosphate

According to popular belief, “the use of boron in insulation classified as ecological did not fit the image. As a result, manufacturers looked for new alternatives and turned to ammonium polyphosphate, a substitute additive. However, this emits a strong ammonia odor that can exceed the authorized thresholds. Realizing this inconvenience and the proven health risk, the CSTB and the CCFAT have re-authorized the use of boron salt.

Boron salt

Although it presents risks of nephrotoxicity, it is the traditional additive used to manufacture cellulose wadding. It is widely used because it is a flame retardant. It is also bio-soluble, bactericidal, non-volatile, and hygroscopic. Boron salt is classified in the “Reach Directive” through its qualities that can present health risks. This directive determines the classes of use of boron salt and the authorized doses (5.5% maximum).

Manufacturing

Here is the process of this manufacture:

  • The pre-crushing or pre-crushing of the blocks of newspapers via a machine of the same title as the crushers of pebbles. It consists of reducing these last insufficiently small blocks to introduce them in one of these mills: hammers, centrifuges, or plates.
  • The pulverization of paper by hitting it with sledgehammers.

Cellulose wadding is an insulating material obtained from paper recycling (waste from new paper cuts from printing companies, newspapers, books, etc.). The process consists of grinding the recovered paper to obtain cellulose fibers. These are then mixed with water. We obtain a diluted paste which will be mixed with treatment products. Then, this paste is spread on a large canvas. The use of these products allows the wadding to resist rodents, insects, and mold.

Characteristics

insulation

Cellulose wadding is available in bulk, in panels, or in bottles. It has many qualities. It is a material that is:

  • Environmentally friendly
  • Healthy
  • Natural, ecological and renewable

It allows for efficient thermal and acoustic insulation. There are 3 types

Cellulose wadding insulation:

  • Insulation by blowing in the roof
  • Insulation by blowing in a wooden frame wall
  • Blown-in insulation of lost attic space

If you wish to have comfort in terms of insulation, call upon a company specialized in the use of cellulose wadding.

Price

The cost of installing cellulose wadding varies depending on :

  • The craftsman who takes care of all the work
  • The workmanship
  • The support to be insulated
  • The accessibility of the room to be insulated
  • The type of cellulose wadding and the desired thickness
  • The method used

In general, the price per square meter is between 25 dollars and 35 dollars. For insulation by :

Insulation:

insulation

  • For wood-frame wall, the rate is between 20 dollars to 30 dollars per m²
  • On the roof, it is necessary to foresee between 30 dollars to 35 dollars for the m², and blowing off the lost attic, the price is between 25 dollars and 30 dollars per m².

We only have one Earth, and this is why we need to take care of it and treat it like the only home it is. This is why more and more of us are going and leaning into more ecological ways of building. Sound off in the comments section below and tell us what you want to read next.

Everything You Need To Know About Lightning Conductor Installation

Lightning rods are highly recommended for people living in mountainous regions or cities with skyscrapers. It will help you to keep your appliances away from danger. Indeed, this tool allows you to protect your homes in case of a lightning strike.

In this article, we tell you everything about lightning rods in order to protect you from these unavoidable weather hazards.

What is a lightning rod?

lightning

Benjamin Franklin invented the first lightning rod system in the 18th century thanks to a study he made with a kite and the electrical nature of lightning. Indeed, thanks to this study, he was able to implement a device to protect buildings. That, by redirecting directly into the ground, the electricity is discharged during times of storms.

How does a lightning conductor work?

The principle of operation of a lightning conductor is to encourage the lightning to come down on him rather than on the building or elsewhere. To do this, a lightning conductor is mainly composed of a rod placed on a high point. This rod is then connected to the ground by down conductors (metal cables) in order to direct the discharged electricity directly into the ground.

In addition, for the proper functioning of the lightning capture device, the lightning conductor is also made up of grounding conductors connected to each other by metallic grounds.

The different types of lightning conductors

Several types of lightning conductors differ from each other on the market, depending on their usefulness and level of complexity.

1. The lightning conductor with a “simple rod.”

The PTS is composed of a metal tip that can go up to 8 meters high in order to encompass the entire structure to be protected. It is connected to two copper down conductors, which are then connected to earth connections. It can provide protection over a radius of approximately 30 meters. However, it is strictly reserved for the protection of small structures.

2. The “enameled cage.”

The “enameled cage” lightning conductor is composed of a mesh covering the whole structure to be protected. For this purpose, numerous spikes are positioned on the roof, with meshes ranging from 5 to 20 meters long, depending on the level of protection required.

This type of lightning conductor requires a rather high installation cost and is rather reserved for complex buildings.

3. The lightning conductor with “priming device.”

The PDA creates a privileged point of impact on its tip with the help of an ionization device. It is capable of capturing lightning strikes more quickly than a PTS. Moreover, it can also offer a more expansive protection zone (about 120 m). This allows it to protect large structures.

The installation of this type of lightning conductor is inexpensive, despite the fact that it can protect both the building and its surroundings.

Is the installation of a lightning rod mandatory?

Generally, the usefulness of installing a lightning conductor will be determined mainly by the geographical location of your home. Obviously, storms are more prevalent in mountainous regions than elsewhere.

Nevertheless, if you have the means, nothing prevents you from installing this protection device, even if you are located in a region that is not very affected by lightning strikes.

Procedure for installing a lightning conductor

This lightning protection device can easily be found in stores. However, the installation of a lightning conductor always requires the intervention of a professional. Indeed, the lightning conductor, placed at the top of your house, must respect strict characteristics, including:

  • The position of the tip must be above the highest point.
  • The resistance of the earth connection must be at the lowest level.
  • The cable connecting the lightning conductor to the ground must be short and direct. It must be separated from any other type of pipe (gas, water…)
