Cowdroy Foam Gap Filler White 10mm X 5m

Cowdroy Foam Gap Filler is a tubular foam strip designed for use as a gap-filling backstop prior to caulking. The 10mm diameter on a 5m roll means it can fill gaps up to 9mm in size. This gap filler is closed-cell foam and can be compressed into gaps and joints to fill them quickly before applying the sealant. The caulking material creates a tight seal that controls the depth of your sealant or adhesive, which can increase resistance to moisture penetration, preventing rot and water damage.

• Compresses into gaps, cracks and joints
