Greater “racking” strength
Spray polyurethane foam has a higher racking strength, which adds structural strength and enhances overall building stability. In fact, spray foam is the only insulation material that adds structure integrity. It adheres to the cavities of the walls and in between ceiling joists making them more rigid to protect against cracking, shifting, or shaking during extreme weather conditions. NAHB Research demonstrated SPF filled walls could add from 75% to 200% racking strength to walls of OSB, plywood, light gauge metal, vinyl siding, or gypsum board.
Highly resistant during severe weather events
Not only does closed spray foam withstand the effects of high winds, but it also performs well under wet conditions. The material is water resistant, has minimal water absorption, and is classified as an acceptable flood resistant material. FEMA has published a rating system ranking building products from 1 to 5(not acceptable to highly acceptable). SPF carries a “5” rating for its outstanding water-resistant qualities.
Prevents bugs and rodents
Spray foam is effective at filling tiny cracks and gaps within walls and attic rafters. Rodents and insects such as rats, mice, cockroaches and other insects can enter through the tiniest of holes, leaving behind waste or destroying your attic storage. Koala spray foam insulation creates a durable barrier that seals all unseen entry points, making it an optimal insect and pest resistant option.
With the increasing demand for comfort and energy efficiency, spray foam is the optimal choice for your insulation needs. It can actually strengthen walls and has low vapor permeance (moisture transmission) and is ideal in rooms where sound-reduction is desired such as in home theaters or, for a light sleeper, bedrooms.
Koala technicians are trained in handling the spray foam components and in completing the installation safely. We guarantee we will prepare the job site to meet all safety standards!
