Install FOAMGLAS pipe insulation by cutting the tube to length with a fine-tooth saw, applying a compatible vapor-retarder adhesive to joints, and sealing all seams with pressure-sensitive tape. Ensure the pipe surface is clean and dry. For plenum-rated applications, follow local fire codes and use approved sealants to maintain the vapor barrier.
