Insulating a crawl space, when done properly, is a great way to save energy. We recommend both sealing and insulating your crawl space to maximize the money you save. By sealing your crawl space before insulating, you will prevent air leaks and protect the crawl space from moisture issues.
Rodents can enter a crawl space through vents and similar openings.
Once in your home, they will nest in the warm fiberglass insulation, finding plenty of food and moisture in the crawl space to live on.
A damp crawl space environment can also attract other pests, such as termites, carpenter ants, and wood-boring beetles.
Fiberglass soaks up moisture and humidity like a sponge, and it makes great nesting material for mice and rats. Wet, waterlogged fiberglass will become heavy, causing it to sag off your floor joists and end up on the floor. Wet fiberglass also loses its R-Value -- its ability to stop air flow.
Once it lands on your floor, fiberglass insulation becomes a useless, wet, mouldy mess that will eventually need to be cleaned up.
At Island Basement Systems, we recommend sealing and insulating your home with 2.4" rigid insulation on your crawl space walls.
While your crawl space walls provide the maximum opportunity for saving money through crawl space insulation, it's a good idea to also insulate your crawl space floor.
Since crawl spaces are located underground, your crawl space floors will retain a year-round temperature of about 55 °F. If left uninsulated, this can mean a lot of cold in your crawl space!
To insulate crawl space floors, we use TerraBlock™ Crawl Space Floor Insulation. Made from ¾" of closed-cell foam insulation, it includes a padded, puncture-resistant design that makes it appropriate for crawl-on access by service workers and homeowners alike.
TerraBlock™ is fully compatible with our crawl space liner system, and it can be easily integrated with our crawl space waterproofing systems as well. Combined with SilverGlo™ on your walls, it's a fantastic way to save money and enjoy a healthier, more valuable home!
