This video shows the benefits of spray foam insulation in your homes attic.
Attic spray foam insulation is often considered the most effective type of insulation, but how does it actually work? Simply put, spray foam insulation consists of two synthetic materials which, when mixed properly, expand their liquid volume up to 60 times. Spray foam insulation creates a thick layer of powerful thermal insulator, filling all the gaps and cracks in your attic. Because the materials solidify once dry, attic spray foam insulation is completely water-resistant and does not release any particles or allergens into the air. Traditional insulators - like fiberglass - are known to release particles that can cause allergic reactions and respiratory complications.
Spray polyurethane foam insulation is commonly used in one of two ways to insulate your attic space: vented attic and non-vented attic. With a move towards Passive homes, non-vented attics are becoming the obvious choice for enhanced energy efficiency. Non-vented attic insulation is applied directly to the underside of the roof sheathing to insulate the entire attic from exterior temperatures. FOAM-LOK spray foam is installed between the roof rafters, along the soffit areas and directly to all interior surfaces such as gable walls and dormers to produce an air tight building envelope making the attic a part of the conditioned space of the home.
