Pink Fiberglass Insulation is designed to maintain insulating power overtime. This insulation will not hold water, preventing permanent loss of R-value. When properly installed, it will not settle or deteriorate, according to the manufacturer. The insulating materials in this insulation are also noncombustible. Certified by SCS, the Pink Fiberglass insulation now has a higher level of certified recycled content. The insulation is manufactured with recycled glass, helping to reduce energy use and C02 emissions.
