Window And Door Flashing Tape

The window and door flashing tape produced by Xiongxian Xiashi Packing Co., Ltd. are essential auxiliary materials for the exterior wall insulation system. They can reduce the operating costs of building HVAC systems by up to 40% and reduce the risk of mold growth on the walls by 92%.

Product Composition & Working Principle

House Dress Jinbo window and door flashing tape is divided into exterior breathable type and interior vapor-tight type, adopting PE+PP spun-bond composite substrate compounded with solvent-free pure butyl adhesive layer, developed synchronously with the brand’s waterproof breathable membrane in 2014 for European and American green building market demand.

The core physical principle follows the microporous vapor separation logic of House Dress waterproof breathable membrane: the minimum diameter of liquid rainwater droplets reaches 20μm, while water vapor molecule diameter is only 0.0004μm. The exterior breathable flashing tape is equipped with uniform micro-pores to discharge wall cavity vapor outward via diffusion, and blocks liquid rainwater relying on surface tension; the dense substrate of interior vapor-tight flashing tape isolates high-humidity indoor vapor from invading thermal insulation layers, forming bidirectional vapor control coordination with waterproof breathable membrane and vapor barrier membrane to eliminate condensation accumulation fundamentally.

Standard Technical Parameter Sheet

Standard Construction Technical Specifications

Substrate pretreatment: Remove dust, grease and residual mortar on window opening surfaces, and ensure full dryness; coat interface treating agent on rough porous concrete base to enhance adhesive bonding force.

Corner reinforced treatment: Reserve flashing width of 1–1.5 times window joint width for internal and external corners to eliminate deformation gap hidden dangers.

Overlap laying standard: Maintain minimum 10cm lap width between adjacent tape rolls to form continuous sealing layers.

Debubbling compaction: Use matched scraping compaction tools to fully extrude air bubbles between tape and substrate for complete surface fitting.

System integration sealing: Connect tape edges seamlessly with House Dress waterproof breathable membrane, and separately lay breathable tape on exterior wall side,vapor-tight tape on indoor warm side according to vapor control design requirements.
