Reuse old fiberglass batts?
We are gutting and rehabbing an old house. We are pulling out the old fiberglass insulation from the walls and ceilings, and we have quite a large collection of the batts. Can the insulation be reused?
Some of it is obviously in bad shape, but a lot of it is still fluffy and pink with some discoloration. I know the batts acted as an air filter for the (very) leaky house over the decades, and so they have collected dust and dirt.
How much has that degraded the effectiveness of the insulation? Would it be worth salvaging some of the insulation?
It just seems a shame to send it all to the landfill.
