Certified Spray Foam Installers Sunlight Contractors New Orleans crawl space insulation

Remember when you were a kid and you were sure something scary lurked in the dark recesses of your home’s crawl space? Turns out, you weren’t too far off base. When left uninsulated, crawl spaces can be the source of many problems for homeowners.

Especially in the older, raised cottages of southern Louisiana, original hardwood floors and gradually loosening joints allow significant (and costly) air passage. During the summer, heat rises through the cracks, pushing conditioned air out. During the winter, the cold snakes its way in, leaving floors icy to little feet. Closed-cell spray foam seals these cracks, eliminating not only the passage of air and loss of temperature, but also preventing infestations by termites and other insects living beneath your home.

Closed-cell spray foam is also a moisture repellent, which means in addition to insulation, it seals your floorboards from the damp soil, preventing rot. Conversely, fiberglass batt insulation absorbs moisture, becoming soggy, mold-ridden, and compressed when place between the floor joists of your crawl space. This reduces the R-value of the insulation and creates a breeding ground for mold and mildew.

Why Install Spray Foam Insulation?

Air moves in and out of a home through every hole, crack, and crevice. Roughly one-third of air infiltrates through walls, ceilings and floors. Adding an advanced insulation system is necessary to achieve optimal building performance. Spray Foam is that advanced insulation system.

Spray foam insulation can maximize a homeowner's investment by sealing the building envelope to stop conditioned indoor air from escaping and prevent unconditioned air from entering a home.

Air exchange in and out of a home is a leading cause of escalated energy bills. The mechanical systems that heat and cool buildings are continuously operating; reducing extreme temperature variations saves on the overuse of mechanical systems and leads to lower energy bills.
