PolySeal Sill Plate Sealer
Plymouth Foam’s polyseal sill plate sealer is made from a lightweight polyethylene foam. By filling irregularities between the sill plate and the foundation, air infiltration is significantly reduced to provide savings on heating and air conditioning costs. Its durable, moisture-resistant characteristics aid in the prevention of water and insect intrusion, two of the leading caused of sil plate rot.
