What Are The Advantages Of Foam?
The major advantage of Spray Foam is that it does more than just insulate. It also windproofs 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.
