Crawl space insulation is a key factor in maintaining energy efficiency and comfort in your home. Unfortunately, many crawl spaces are poorly insulated – or not insulated at all!
The experts Green Building Advisor are straight forward: “Crawl space walls should be insulated with rigid foam or closed-cell spray polyurethane foam.”
Many crawl spaces may have been insulated, but the materials are not sufficient – or ventilation may be causing more harm than good.
AGL Spray Foam has insulated and encapsulated hundreds of crawl spaces in Greater Philadelphia and knows what it takes to eliminate every problem your crawl space might cause.
My Crawl Space Is Up To Code. Is This A Bad Thing?
It depends! Old building codes required crawl spaces to be vented.
Despite the rumor that vented spaces allow for smooth air circulation (thought to be beneficial in the sweltering summer months), research has determined that vented crawl spaces are actually more prone to moisture problems and mold.
Here’s what’s really happening in your vented crawl space: as hot, humid air filters through your home, it comes in contact with the cool surfaces under the house. This leads to condensation buildup, which can lead to a mold infestation and thousands of dollars in repairs.
