Coping With Wet Insulation

If the fiberglass within your wall cavity or in your attic becomes wet from a leaky roof or burst pipe it will lose insulating effectiveness until the material dries out over time. However, if the fiberglass batts or loose fill insulation becomes inundated with dirty flood water and becomes soaked throughout, the fibers may become cemented together with dirt and form clumps. Compressed or contaminated fiberglass will no longer be very effective as insulation and it should be replaced.
