Wealter non-self-adhesive waterproof vapor permeable membrane for doors and windows is made of high-strength membrane combined with high-performance butyl self-adhesive pre-pasted strips. It is mainly used on the outdoor side of the gap between windows, doors and walls, and is used together with specialized MS adhesive for doors and windows, which can play a role in waterproofing, airtightness, and water vapor management, improving the energy-saving effect of the outer building envelope.

Features:

High strength: The raw materials used are from virgin materials of high-quality manufacturers, and recycled materials are never used. They have stronger tensile strength under the same weight and can effectively cope with stress and deformation during use.

Good vapor permeability: It has been targeted to strengthen the strength and impermeability and other properties, and still has high water vapor permeability, ensuring that the insulation layer and the external gas exchanges smoothly, keeping the insulation layer in a dry state, and enhancing the energy-saving efficiency.

Impermeability: With excellent impermeability, it can effectively and safely maintain the waterproof function for the condensation and leakage water that may occur in the enclosure structure, and guarantee the dryness of the insulation layer as well as the overall watertightness of the building.

Aging resistance: The raw material ratio and selection process have been specially designed to improve the aging resistance, which can well adapt to the application scenarios.

Mainly used for airtight sealing between doors and windows and outer building envelope in ultra-low energy buildings; airtight sealing between the through wall pipeline and the outer building envelope; airtight sealing between the outer building envelope layers of different materials and building forms.
