Extreme weather: Protecting walls, basements and crawlspaces with spray foam
Spray foam can be a key component of the remediation efforts following extreme weather events such as hurricanes or floods. With these weather events, significant damage can be sustained by buildings, yet the aftermath of hurricane-strength winds and the threat of wind-driven rain and flooding can be addressed with proper planning and understanding.
Icynene spray foams are considered air-impermeable materials that help deflect wind and wind-driven rain. For instance, light-density spray foams like Icynene Classic™ and Icynene Classic Max™ are able to reject water penetration and have a low water absorption of less than 5%. Additionally, medium-density spray foams like Icynene MD-C-200 are considered to be water resistant barriers with very low water absorption of less than one percent. Medium-density spray foams are able to provide additional ‘racking’ strength to help resist the high winds of a storm or hurricane.
When it comes to the most vulnerable areas of the home, basements and crawlspaces, spray foam can perform to protect these areas. As an air barrier, spray foam helps limit moist air penetrating the building. In non flood-prone areas, light-density spray foam’s air-barrier qualities allow bi-directional assembly drying. This enables basement walls to dry out should they become wet. In flood zones, medium-density spray foam can be used since it does not absorb moisture.
Armed with the knowledge of how spray foam insulation can help protect a building, homeowners and business owners can be assured in a quality product that will work for the life of the building even during extreme weather events. Icynene’s Building Science and Engineering teams can discuss with you how you can successfully use spray foam in your hurricane-proof designs.
