What Are The Advantages Of Foam?
The major advantage of Spray Foam is that it does more than just insulate. It also wind-proofs wall and ceiling cavities from air movement, with a 3 1/2" sample of foam proving to be about 24 times less permeable to air infiltration than a similar thickness of fiberglass batt. In addition, the insulating power of All Tech Insulation products are not diminished by lower temperatures or by air movement. Its R-value performs as stated. By contrast, some building experts state that an R-13 fiberglass batt in the presence of a 10 mile per hour breeze (the real world) diminishes the insulating power of a batt to an R-5! Hardly the kind of protection from heat and cold you were hoping to arrange for your family.
