Polyurethane spray foam insulation is often praised for its ability to make homes comfortable and more energy-efficient, but in fact, it has another benefit. It can actually make buildings sturdier, which is good news especially for those in hurricane zones.
Spray Foam in Hurricane-Prone Regions
Those along the Atlantic and Gulf Coasts should be especially aware of spray foam's ability to strengthen walls and stabilize structures. Having this substance applied to an existing home before hurricane season hits could mean the difference between a home that's still standing in the spring, and one that has succumbed to the elements.
There are several areas where spray foam should be applied to strengthen homes. One is on the interior of the roof. According to recent studies, applying SPF to a roof makes it three times less likely to be uplifted by high winds. Another place to have spray foam applied is in wall cavities. It increases racking strength, which is the walls' abilities to withstand high winds.
Spray Foam Insulation and Water Protection
Another way in which polyurethane spray foam insulation protects homes is by preventing water from coming into contract with certain building materials. When the materials stay dry, they stray stronger and are less likely to succumb to wear. On flat of low-sloped roofs, applying spray foam allows water to roll over the fasteners and seams, rather than seeping into them. Roofs sealed with spray foam are also less penetrable by hail and flying debris.
Whether or not you live in a storm zone, applying spray foam is a good way to increase your home's durability and make it less prone to damage. Visit the NCFI Polyurethanes' website, and use our "find an applicator" tool to find a certified applicator near you.
