Premium Energy Sill Sealer

The only Self-Adhesive Air and Moisture Sill Barrier Premium Energy Sill Sealer combines a full 3/8″ closed cell polyethylene foam with an aggressive self adhesive waterproofing membrane that conforms and seals off the voids and irregularities between the top of the foundation and sill plate. This unique design combines the peel and stick waterproofing characteristics of Protecto Wrap’s waterproofing membrane with a 3/8″ thick closed cell foam sill sealer forming a gasket seal to virtually eliminate any air, moisture and insect/rodent infiltration beneath the sill plate.
