What is Fiberglass Batt Insulation?
Fiberglass Batt Insulation is made of extremely fine glass fibers that comes in batts, loose-fill and even rigid boards. Fiberglass insulation is made in a process where spun-glass fibers are made into batts by using heat to stream melt into spun fibers through a rotating flywheel or drawn through tiny holes in rotating spinners. Fiberglass insulation creates thousands of small, porous spaces of air pockets to provide enough heat flow resistance for proper insulation. The insulation slows the spread of heat, cold and sound in the structures it is installed in. Manufacturers typically deliver medium to high density fiberglass insulation with different R-values. Fiberglass insulation is not waterproof but does provide some degree of moisture resistance. Fiberglass insulation can typically last the lifetime of the house itself.
