Spray foam insulation can be a great alternative to traditional insulation materials like rock wool, fiberglass and cellulose. It is resistant to heat loss, wood decay, mold, and dampness and will last a lifetime. It dramatically reduces outside noise entering your home or 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 quickly turns into thick, dense foam insulation. It protects from heat loss, mold, wood rot, and dampness. It does not degrade, break down, or lasts forever.
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.
Open cell spray foam is used almost exclusively for attic insulation. To allow moisture to escape, Irish building regulations require that there be a minimum of 50mm between the insulation material and the roof deck.
