Does polyurethane foam need to be removed after a flood?2021-04-22T09:38:43-04:00

Unlike other insulation products, BOREAL Nature polyurethane foam does not need to be removed after a flood. In most cases, it remains intact, does not disintegrate and regains all its properties once dried out.

What is radon?2021-04-22T09:40:30-04:00

Radon is a radioactive gas that occurs naturally in the environment. It is created by the decay of uranium in soil, rock and water. It is an odorless, colorless gas that moves freely through the soil, allowing it to be released into the atmosphere and seep into buildings. In the open air, the amount of radon is minimal and does not pose a health risk. However, a significant accumulation of this gas in your building can cause certain risks. According to Health Canada, radon is the second leading cause of lung cancer after smoking.

A building insulated with BOREAL Nature polyurethane foam resists radon gas infiltration in your home.

Is polyurethane foam durable?2021-04-22T09:44:58-04:00

BOREAL Nature polyurethane foam will remain in place for the life of the building.

What is the ideal temperature for applying spray polyurethane foam?2021-04-22T10:01:15-04:00

Do you have any useful links on asbestos?2021-04-22T10:35:12-04:00
Do your walls contain asbestos?2021-04-22T10:40:41-04:00

Houses built before 1985 may contain siding made of plaster mixed with asbestos. This practice was widespread until the arrival of drywall, commonly called “gypsum”. In other words, if your walls are not made of gypsum, it is important to check if your walls contain asbestos.

An article published in La Presse*: ”Gypsum wallboard appeared at the end of the 1960s… Before that, most plaster walls contained asbestos. Asbestos is no longer used in Quebec since 1985, unless it is mixed with cement or asphalt… But in Montreal and elsewhere in Quebec, thousands of people are still exposed to it, most often unknowingly… This means that all renovation work in old houses is likely to have released carcinogenic asbestos fibres into the atmosphere… ” If you’re knocking down entire walls, you have to confine the entire job site in negative pressure, and obviously protect yourself adequately.”

What is asbestos?2021-04-22T10:41:58-04:00

Asbestos is a natural mineral fiber, frequently used in residential construction because of its resistance to chemicals and also because of its non-combustibility, knowing that asbestos has great thermal properties. At one time, asbestos was considered a “magic mineral”. A star product for your home. Today, asbestos is recognized as a dangerous carcinogen and its use is prohibited in Canada and in most industrialized countries.

Houses built between 1920 and 1985 are likely to contain asbestos-based materials. Since that time, its use has ceased and the asbestos industry and products are highly regulated in Canada.

How do you install soundproofing?2021-04-22T10:46:53-04:00

The quality of installation of an acoustic insulation is essential.

Noise propagates through the air, but also by conduction. The capabilities of the product you choose are important, but to obtain a really effective soundproofing you must take into account the structure of the building and what is in the walls. Everything can conduct noise, even a power outlet or a ceiling beam. Our installation will therefore take into account all the parameters in order to reduce both the intensity of the noise and its dispersion in the building.

Whether you dream of no longer living at the same time as your neighbors, or of soundproofing a child’s room, a home theater, a playroom, your laundry room or your garage, each member of your family will be able to use his or her space without disturbing the others or without being disturbed!

What is the best soundproofing product?2021-04-22T10:48:31-04:00

Cellulose is an excellent acoustic insulator that has the added advantage of being an excellent thermal insulator. It can be used in new constructions as well as in renovations. It can be installed before closing the walls in a new house or blown into closed walls. It can also be blown into the attic.

Is it possible to soundproof a house built a long time ago?2021-04-22T10:50:21-04:00

We can improve the soundproofing of an entire house, the common walls or between two floors. It is also possible if you live in a condominium. However, if you want to soundproof a single room, it is not enough to insulate only the walls. You must take into account the structure of the building, the passage of beams and ducts as well as everything that can conduct sound, because it will propagate through these elements. When it comes to soundproofing, you can’t do things by halves. If it’s poorly thought out and installed, the insulation will be useless. You will have wasted time and money without achieving your goal. Do not hesitate to contact us, we will give you the right information. We will offer you the solution that will solve your noise problems at the right price.

How do I know if my house contains asbestos?2021-04-22T11:10:52-04:00

Don’t start any work without knowing if your home contains asbestos! The only way is to take samples and do tests.

We do the vermiculite or Zonolite testing, it’s fast and accurate. The test consists of taking samples in the attic of your home to determine if asbestos is present. Air tests are also available. These samples are then sent to a laboratory for analysis. We will get your answer within 48 to 72 hours. We also offer a rapid analysis service if you need an answer within 24 hours.

When do you need to know if your home contains asbestos?2021-04-22T11:18:06-04:00

Honestly, everyone should know if their home contains asbestos, so they can act knowledgeably and appropriately. However, there are situations where this becomes imperative:

Before undertaking any work that affects areas potentially insulated with vermiculite
Before making an extension
Before selling your property
Before building or storing in your attic

A detection test and decontamination work are required to sell a property insulated with materials containing asbestos fibres. We are committed to offering you a detailed follow-up of the decontamination work. This will allow you to satisfy all parties involved in the sale and conclude your transaction with complete peace of mind.

Can I do the decontamination myself?2021-04-22T11:19:52-04:00

You should never attempt to do the decontamination yourself…

Our expertise in insulation allows us to carry out vermiculite decontamination work with the rigor and standards that are required:

  • Protection of the premises
  • Negative pressure to prevent any dispersion of contaminants
  • Protection of workers
  • Removal and safe destruction of contaminated materials

Once the vermiculite removal work is completed, we will advise you on how to re-insulate your home so that it meets current standards. This new, more efficient insulation could allow you to realize significant energy savings.

What are the dangers of asbestos to your health?2021-04-22T11:23:57-04:00

The health effects of long-term exposure to asbestos include lung damage such as asbestosis, which is the permanent scarring of lung tissue leading to chronic respiratory disease. All forms of asbestos have also been shown to cause cancer of the lung, esophagus, larynx, stomach and colon, as well as mesothelioma (an extremely virulent form of cancer affecting the pleura, peritoneum or heart lining).

Is it enough to choose the material with the best R-value?2021-04-22T11:30:47-04:00

It is true that in order to finalize your choice, you must take into account the R-value of an insulator and of course its price. However, the choice of an insulator is primarily based on its usefulness and the location where it will be installed. Not all insulation is suitable for all architectures, slopes and support materials. For example, some insulations are not suitable for basements, but are ideal for attics. Others are ideal for the exterior envelope of a new building, but will be difficult to apply if the walls are already closed. Some cannot be applied to all materials.

Choosing an insulation with a high R-value is not enough, it must be adapted to your home and its installation must be perfect to avoid thermal bridges, pockets and air leaks. Moreover, the entire building envelope must be taken into account to ensure that the thermal and acoustic insulation is truly effective.

We are here to advise you on the most effective insulation and techniques to meet your objectives and budget.

What is the R-value assigned to different insulating materials?2021-04-22T11:33:48-04:00

The R-value (also called RSI in the metric system) is the thermal resistance value of a material. It gives a good indication of the performance of an insulating product. The higher the R or RSI value, the more resistant the material will be to heat transfer and therefore the more insulating it will be.

What are the different insulating products?2021-04-22T11:35:05-04:00

There are many different insulation materials and installation methods. We have selected for you the most efficient techniques and products on the market, each with specific advantages depending on the objective. The various processes and products also differ to adapt to the configuration of the building or to be integrated in a new construction or during renovations. In addition, some will provide thermal insulation only and others will have the added benefit of providing acoustic insulation.

We are here to advise you on the insulation solution that will meet your objectives within your budget.
