Simplified construction with one-touch operation, easier than tape, and stabilization of quality! This is a revolutionary waterproof fitting for penetration areas around ducts.

■Necessity of Waterproofing for Wall Penetrations Holes for ducts and sleeve pipes that pass through the exterior wall are often prone to rainwater intrusion, which can lead to leaks. Typically, sealing treatment is performed using caulking, but secondary waterproofing on the interior side of the wall is essential. Furthermore, treatment with only sealing materials is not recognized under the new housing warranty (JIO), and secondary waterproofing is required as a construction standard.

LS Pipe Hats are standardized waterproofing materials for wall penetrations that integrate waterproof tape. Compared to traditional tape installation, they offer simplified installation, stabilized quality, and improved waterproof reliability.
