How does SPF reduce energy use in buildings?
Is it environmentally certified?
Yes, Spray Foam Insulation is an ecological product certified by an independant agency: "the Environmental Choice Program (EPC-40) of Environment of Canada".
Is it possible for a homeowner to install this foam on their own?
Spray Foam Insulation has to be installed by a certified contractor with specialty proportioning equipment. The installer has been trained to work with the chemicals involved and has also been trained in building science to provide the best installation possible.
How long does Spray Foam Last?
Aging is not an issue with Spray Foam. It is inert, and its physical and insulating properties are constant.
Environmentally Speaking, Is There Anything to Worry About?
No. Spray foam has been thoroughly tested. Once it has aged for 30 days it is a stable product and no longer has any detectable emissions. Spray Foam has been used in many of the "Health Homes" built all over Canada.
