Since fiberglass does not absorb moisture, PINK fiberglass from Owens Corning, Toledo, Ohio, will not hold water, thereby resisting any permanent loss of R-value. Plus, when properly installed, it will not settle or deteriorate, helping to ensure that the insulating value is maintained. The insulating materials in PINK fiberglass insulation are noncombustible, and the insulation will not rot or decay, support fungus or mold growth, or sustain insects. Available in R-values from 13 to 38, PINK fiber glass insulation can used for all insulating projects — from attics to interior walls to exterior walls.
