Doesn't foam insulation release toxic fumes?

Modern polyurethane spray foams do not contain or release any toxic gases. They are not to be confused with other products used to fill existing wall cavities, although we can use injection foams to this effect, our foams are non-toxic and are safe for home insulation.

How much foam do I need to achieve an R-value of __?

This depends on the density of foam used, but polyurethane spray foam has excellent thermal properties. Our most popular closed cell foam has an R-value of 1.23 per 25mm, which makes it the most efficient insulation available for residential housing uses.

Will the foam absorb moisture?

Our closed cell foam has a 90% closed structure which drastically reduces the chances of water absorption or transmission through the foam.

 What is the difference between open and closed-cell foam?

The primary difference in function between open and closed-cell foams is the transfer of moisture vapour through the foam. Closed cell foams do not allow vapour to pass through whereas open cell foams do.
