Spray foam insulation can be a great alternative to traditional insulation materials like rock wool, fiberglass and cellulose. Protects from heat loss, woodrot, mold, and dampness. Lasts a lifetime. The noise of the outside environment is dramatically reduced from entering the home and business.
Spray foam insulation can be made from two materials: isocyanate (a polyol resin) and is gently heated. They then come together at a tip of a sprayer to form an expanding mousse that is applied to a certain area. The liquid quickly turns into thick, dense foam insulation. It resists heat loss, wood-rot, mold, and dampness. It doesn’t degrade and it lasts a lifetime.
Spray foam insulation’s main attribute is its ability “air seal”, which results into an airtight envelope within buildings. Air sealing can reduce heat loss from the home, which will help you save money on utility bills. It also keeps your home cooler in the summer.
Insulation in attics is almost always sprayed using open cell spray foam. This allows moisture to escape from your structure. Irish building regulations require that a 50mm gap be maintained between the roof deck, felt, and the top of insulation material.
