Butyl Window And Door Flashing Tape

The Jinbo Butyl Window and Door Flashing Tapes produced by Xiashi Packing  Factory are engineering-grade weather-resistant and watertight materials that comply with industry group standards;  When paired with the full range of House Dress Jinbo breathable membranes, these products enable the construction of a comprehensive wall protection system capable of bidirectional moisture control and providing autonomous dehumidification and moisture prevention.

Core Engineering Functions

Thoroughly seal the window opening's water leakage path.

The gap between window/door frames and the wall is the highest risk point for building water leakage; conventional sealing materials may age and crack within 1–3 years; in contrast, the House Dress Butyl Window and Door Flashing Tape can withstand a 1000 mm water column for 2 hours without leaking, fully encapsulating all joints at the window sill, window side, and window top, thereby providing protection against long-term wind and rain erosion.

Enhance building airtightness to achieve up to 40% reduction in heating and cooling energy consumption – NIST

Official reports confirm that air infiltration through window and door gaps is the primary cause of energy loss in buildings; by sealing all air-leaking gaps using Butyl Window and Door Flashing Tape in conjunction with a waterproof vapor-permeable film system, measured data from industrial projects show a 38.7% reduction in HVAC costs.

Eliminates wall condensation and extends building lifespan

Condensation formed within walls due to temperature differences between the interior and exterior can damage the insulation layer and corrode the steel structure; the use of separate breathable and vapor-barrier rubber strips on both sides creates bidirectional moisture control, with field monitoring data showing that the probability of mold growth on walls is reduced by 92%.

The nail hole features self-sealing properties, effectively preventing secondary leakage.

Butyl rubber exhibits micro-flow self-healing properties; when an insulation nail pierces the adhesive tape, the adhesive layer automatically encapsulates the gap between the nail shank, eliminating the need for additional adhesive application to seal potential water leakage at the nail hole.

All-weather long-term weather resistance

Stable operating range: –40°C to 80°C; after 168 hours of thermal aging at 80°C and a 4-month UV accelerated aging test, the product shows no cracking, delamination, or powdering; it is suitable for various environments, including rainy coastal regions in southern China, extremely cold regions in northern China, and high-altitude areas with intense ultraviolet radiation; the product has demonstrated stable outdoor performance over 6 years without any failure records.
