Expandagap BG1 is a fine cell polyurethene foam in precompressed form, specifically designed to expand to fill regular or irregular gaps and joints to provide a permanent flexible seal in a wide range of details. It responds to continued expansion and contraction cycles caused by thermal and structural movement. Expands to approximately 5 times its pre-compressed thickness. Expandagap BG1 provides sound reduction when installed.
