INNER-SEAL is a multi-purpose, UL-classified, one-component polyurethane foam designed specifically for window and door installation and retro-fit applications. Apply INNER-SEAL onto any clean surface to fill and seal around windows and door frame joints, beneath base plates, mud sills, top plate penetrations, corner joints, T-joints, exterior cracks, around utility panels, pipes and duct penetrations. A critical advantage of this industrial/construction grade foam is its extremely low pressure build while curing, which greatly reduces the chance of bowing.
