Quels sont les avantages de l'isolation à mousse de polyuréthane pulvérisée?

La mousse de polyuréthane a plusieurs avantages comparativement aux options d'isolation traditionnels:

• La mousse peut occuper presque tout l'espace, assurant même la plus petite des fissures et des trous sont scellés. Cela signifie une maison plus chaude en hiver et une maison plus fraîche en été. Cela signifie également une réduction des coûts d'énergie.
• La mousse peut s'adhérer à la surface sous les planchers.
• Parce qu'elle remplit le plus petit des espaces, il n'y a pas d'ouvertures pour les insectes et les rongeurs.
• Parce qu'elle remplit les fissures minuscules, elle peut réduire les allergènes et la pollution sonore.
• Il n'ya pas de particules de fibre de verre flottant autour.
• Il n'y a pas d'émissions nocives.
• Elle est durable et de longue-durée.
• Ses qualités d’étanchéité et de pare-vapeur la rendent résistante à la moisissure et à la désintégration causée par l’humidité.

How does spray foam insulation work?

Spray foam insulation is applied as a liquid, using a nozzle not unlike a fire hose. It looks like paint when first applied, but is actually a combination of two substances that blend together at the nozzle and immediately begin to cure. The curing process—which happens within seconds—expands the liquid into a thick foam, which then fills the space and creates an air-tight seal.

How does spray foam insulation reduce energy costs?

Foam insulation serves two purposes in one application—it fills empty spaces with an insulating material and it creates a tight air barrier. Because it fills holes of every shape and size and can fit around odd shaped objects, foam is able to create a very tight seal. A tight seal means no escaping hot or cool air, and therefore, lower utility bills. You spend your money heating your home, not the outdoors.

What is open cell versus closed cell insulation?

When it comes to spray foam insulators, products divide into open cell and closed cell options. Open cell insulation is, as the name suggests, made from tiny foam cells that are not completely closed. The density of an open cell insulator is typically ½ lb. In closed cell insulation, the foam cells are closed and filled with a gas that helps expand the foam and create a tight barrier. The density of a closed cell insulator is typically 2 lbs. The advantages of closed cell foam include its strength, higher R-value, and its greater resistance to the leakage of air or water vapor.

Because of its huge advantages in quality, KinLar Insulation Inc. firmly believes in a closed cell product.

What is R-value?

R-value is a unit of measure used to define thermal resistance, or the ability to resist heat flow. The higher the R-value, the greater the resistance to heat loss. The R-value is a very useful measurement, but it has limits. It only measures conduction. Conduction—where heat escapes through solid objects—accounts for only 20% of a building’s heat loss, while convection—where heat escapes via air moving from one place to another—accounts for the rest. It takes as little as a ¼ inch of Polarfoam PF-7300 SOYA foam to stop 99% of convection heat loss.

What’s the R-value of Polarfoam PF-7300 SOYA?

The R-value of KinLar’s spray foam insulation is R-6 per inch.

Will spray foam insulation stick to cement?

Sprayed Polyurethane foam will form a bond on virtually all substrates including wood, stone, gravel, brick and cement. The area needs to be reasonably clean and dry to the touch.

Do we have to leave the home while the foam insulation is being applied?

Not necessarily. If someone has a low tolerance for a mild paint or chemical odor, then we would suggest they stay away for at least 24 hours. In many cases we apply the spray foam insulation while occupants are on other levels of the property.

What about off-gassing?

All manufactured materials will off-gas to some degree, and foam insulation is no exception. However, Polarfoam PF-7300 SOYA is a medium-density spray foam which meets the CAN/ULC S705.1 material standard. The CUFCA requires that all of its licensed manufacturers meet a maximum limit of 1/100 of the government’s allowable limit. Polarfoam PF-7300 SOYA met this requirement easily.

What exactly is Polarfoam PF-7300 SOYA?

Polarfoam PF-7300 SOYA is a two component closed cell spray-applied rigid polyurethane foam system distributed by the Canadian company Polyurethane Foam Systems Inc. It’s an innovative ecological product made from renewable vegetable oils and recycled plastic bottles, which uses a Zero Ozone Depletion Substance (ZERO ODS) as a blowing agent.

Polarfoam PF-7300 SOYA is formulated to exceed the requirements of the National Building Code of Canada for foam insulation, and has been evaluated by an independent recognized laboratory to ensure compliance. It has also achieved the Greenguard Environmental Institute’s (www.greenguard.org) GREENGUARD Children & SchoolsSM indoor air quality certification.

It emits no VOCs (Volatile Organic Compounds) or CFCs (Chloro Fluoro Carbons). It contains no formaldehyde or bleach. It insulates as well as any petroleum based spray foam, but without any of the harmful environmental side effects.

Can insulating my home qualify me for rebates?

As environmental issues have increased in importance, various national and provincial programs have arisen to encourage consumers to do their part. It’s possible your insulation project can qualify you for a rebate. Please check the following links to see if you qualify:
