Insulation for crawl spaces is an essential part of getting your home to be as energy efficient as it can be. If you have an older home, your crawl spaces might be ventilated and insulated with fiberglass. This causes serious problems with mold and doesn’t insulate the house very well. The best thing to do if your home is in this state is to have the crawl space encapsulated and have rigid floor insulation boards put in.
Crawl space walls instead of ceiling
Encapsulation of your crawl space means that it will be sealed. If there is a dirt floor, and plastic membrane will be laid down to keep moisture out of the area. If it is a ventilated crawl space, the air ducts will also need to be sealed. Any sources of air leaks will also need to be taken care of. Once the crawl space is encapsulated, insulation can be installed. Rigid foam insulation is the best option for crawl spaces. Unlike fiberglass batts, it doesn’t soak up moisture and grow mold. It is also installed onto the walls of the crawl space so it won’t shift around like lose batts do. This allows for the maximum R-value to be reached when insulating your home’s crawl space. If you seal and insulate the crawl space in your home properly, it will have a positive effect on the efficiency of your home and reduce your energy bills.
