Seal and protect your metal roof with Duco's durable corrugated foam closure strips, proudly made in the USA. Engineered to withstand extreme temperatures, UV exposure, and harsh weather, these chemical-resistant strips won't shrink, crack, or absorb moisture, ensuring a long-lasting, weatherproof seal for nearly any commercial or industrial roofing and siding need. Each of these metal closure strips is 3 feet in length with a ridge every 12 inches in the center for easy installation. Note that adhesives are not included. Beyond sealing gaps and blocking moisture, these R-panel foam closure strips also absorb sound, creating an effective noise barrier for a quieter interior. Featuring interlocking dovetail technology, they seamlessly insert onto matching metal roofing panels for a secure, easy-to-install fit. Lightweight and flexible, Duco's corrugated closure strip foams make insulating your metal roof simpler than ever.
