Product Description
Hollyfoam® Self-expanding Sealing Tape
Self-expanding polyurethane foam tape is a pre-compressed, self-expanding foam tape that is based on a modified material from polyurethane foam. The polyurethane foam expands uniformly to provide a high performance, all-weather seal and is treated with a pressure-sensitive adhesive on one side that can be fixed to one side of the joint. It is specifically designed for sealing joints around windows and doors, expansion joints in concrete, and joints between precast concrete and profile panels.
