FAQ Index :
Q. Is this foam safe?
A. The CCMC evaluated foam insulation has been tested for off gassing, health effects, and numerous other concerns for public safety. We are proud to announce that we have passed all the tests and have full government approval. A report is available through the Canadian Urethane Foam Contractors Assoc (www.cufca.ca).
Q. Is polyurethane foam more expensive than other insulations?
A. Sprayed foam insulation is more expensive to install than fiberglass insulation, but the payback comes back very quickly (5 years or less) on heating or air conditioning costs. The comfort level in your building or residence will also be gratifying when you use foam.
Q. How is foam applied? How can you control the thickness?
A. Our licenced applicators have had extensive training through C.U.F.C.A. Many different spray tip sizes in our spray guns allow an experienced applicator to come within 1/4 inch on a 2" application.
Q. How do I specify foam on a project?
A. There is a master specification available through this office (Shea Foams Ltd.) or from CUFCA. At www.cufca.ca When using this spec. you are automatically assured that a member company will do the work and a third party warranty is in place from the association and the manufacturer. This feature is peace of mind for the Architect and owner in case of dispute.
Q. Is this the insulation we see on metal buildings in agricultural areas?
A. Yes. Spray foam is used extensively on metal buildings, tanks etc. The high R-value (R=6.25 per inch) makes it very good as a condensation control and quick way to insulate.
Q. Can spray foam be applied in cold weather?
A. spray foam is temperature sensitive, therefore in temperatures below -5 degrees C. we have to hoard. When doing a cavity wall where brick is to cover the foam we are not restricted to any requirements that the mortar is not, meaning we can not applicate when too cold , nor can the masons.
Q. Is a vapor Barrier required with spray foam?
A. When a 2 lb. Density foam is 2" or more, then no additional vapor barrier is required. When ½ Lb/cu.Ft. Foam is used then a more open cell structure is present and a vapor barrier (polyethylene 6 mil.) Is required.
