These two areas of your home offer some flexibility in terms of which insulation product to use. Depending on how the space will be used, your estimator can consider which combination of spray foam insulation or batting is most appropriate. Drafty joist header areas are usually sealed and insulated with polyurethane spray foam. We can provide guidance to how to most effectively frame the basement walls ahead of the insulation installation.
The techniques we use to insulate crawl spaces can overcome common problems such as dampness, freezing pipes, or cold floors in the living space above. The recommended R-factor for both basement insulation and crawl space insulation is R-24.
A common upgrade for many of our clients, including those in the Affordable Energy Program, is to vapour-barrier and insulate an unfinished basement.
This type of upgrade is a great way for a client to increase the energy efficiency of their home and reduce their monthly costs, as well as an opportunity to further develop a formerly under-utilized space.
For these types of projects we take great care to seal around all of the fixtures including electric outlets and dryer vents as well as insulating the headers and the basement foundation walls to prevent heat loss. We install R28 worth of Roxul (rock wool) insulation to all of the walls and enclose it with a well sealed and detailed vapour barrier. All of these actions generate a reasonable monthly energy savings, while providing the homeowners a more comfortable home in which to reside.
As a bonus, qualifying customers will have the full cost of this type of project covered by the Affordable Energy Program.
