The Facts about Spray Foam Insulation
Question: Do I have to leave my home during the installation of Spray Foam Insulation?
For any resisdential retrofit projects, you are required to stay out of your home for a period of 24 hours. This is because the part A in all spray foam products is a respiratory irritant. We release a small amount of product into the air during the spraying process. There is no offgassing from our foam and after 24 hours you are safe and clear to renter your home without hesitation.
Question: Since your product is made with Soy, do insects and animals eat it?
Our product is still polyurethane foam and is a cellular plastic. Insects and animals will not eat or nest in our cured product. In fact one of the main reasons for using Spray Foam Insulation is to prevent the intrusion of pests.
Question: Is your product considered a vapour barrier?
Our product, Polarfoam 7300-0 Soya, becomes a vapour barrier at 2" or 50 mm in thickness. This is true for all ccmc approved 2lb medium density closed cell spray foam insulations.
Question: How thick or at what R-value should you install Spray Foam Insulation?
Various areas in your home require different amounts of spray foam. There are so many factors that it isn't possible to list everything here. Please contact Joe Poirier and he will give you the best solution that will suit your project and your budget.
Question: Is your product fire rated? Do I have to cover it with a fire rated material?
There is no such thing as a fire rated spray foam insulation but Polarfoam 7300-0 Soya has the best fire resistance on the market. Our product is half as flamable as the closest competition. All spray foam insulation must be protected with a fire rated material such as drywall, or ask us about our fire rated coatings.
Question: Will spray foam really increase the efficiency in my home?
Yes! At the very minimum, Spray foam insulation is 25% more efficient than traditional insulation. In our experience, medium density closed cell spray foam insulation is closer to 50% more efficient than traditional batt and vapour barrier. The reason that spray foam is so efficient is that it is both an insulation and a vapour barrier in one. It expands to fit all cavity shapes and sizes and creates a perfect air seal to prevent those nasty drafts. We could go into Stack Effect and all the reasons why spray foam works but it basically comes down to one thing, if you can prevent air leaks in your building envelope, you will save energy.
Some areas that are really tough to insulate with traditional insulation are, Headers / Rim Joists (the areas in between the levels of your home), Crawl Spaces, Garage & Patio Ceilings, Cathedral Ceilings, Basement walls and behind any plumbing that may run along the exterior walls of the home.
Question: Does Spray Foam Insulation cost more that batt and vapour barrier?
The initial cost of Spray Foam Insulation is more than traditional batt and vapour barrier. You are normally looking at around 3 times the cost.
When looking at the true cost of Spray Foam Insulation you must factor in the speed of installation, not requiring a plastic vapour barrier and the overal increase in efficiency. In the long term (over a 2-3 year period) Spray Foam Insulation is actually less expensive than traditional batt and vapour barrier.
This means that in just 2-3 years, you will be making money by paying a little more in the begining. This is true even without factoring in all the other benefits of using spray foam.
