Spray foam insulation offers a better alternative to traditional insulation materials like fiberglass, rock wool, cellulose, and polystyrene board. It is resistant to heat loss, wood decay, mold, and dampness and will last a lifetime. This reduces the sound pollution in the environment that surrounds your home or office.
Spray foam insulation is formed when two materials, isocyanate, and a resin polyol are gently heated. The foam expands at the tip if a spray gun and is then applied to a specific area. The liquid transforms quickly into dense, hard foam insulation. It is resistant to heat loss, wood rot and mold, lasts for a lifetime, and doesn’t degrade or go bad.
Spray foam insulation’s greatest attribute is its ability form an “air-seal”, which results in a tight envelope within a building. Air sealing prevents heat from escaping the house. This can help reduce utility bills as well as keep the home cooler during hot months.
Most attic insulation is sprayed with open-cell spray foam. In order to let moisture escape your structure, Irish building regulations mandate that a 50mm air space be left between the roof deck or felt and top of the insulation material.
