Spray foam insulation is an excellent alternative to traditional insulation materials such as fiberglass, rock wool and cellulose. Protects against heat loss and wood rot. It lasts a lifetime. The noise of the outside environment is dramatically reduced from entering the home and business.
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 protects from heat loss, mold, wood rot, and dampness. It does not degrade, break down, or lasts forever.
The most important characteristic of spray foam insulation is its ability to create an “air seal”, which results within an airtight building envelope. Air sealing has the advantage of preventing heat escape from your house. This will reduce utility bills and keep your home cool during the hottest months.
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.
