China Roofing Waterproof Membrane Manufacturers Suppliers Factory - Wholesale Service

Product Description

The roofing waterproof membrane series includes breathable membranes (Breathable Membrane) and foil vapor barriers (Foil Vapour Barrier), specifically designed for building envelope systems. Breathable membranes effectively expel internal moisture from walls/roofs while blocking external rainwater intrusion; vapor barriers prevent indoor humidity from penetrating insulation layers. Used together, they ensure buildings “breathe,” extending structural lifespan and improving energy efficiency.

Product Advantages

- One-Way Breathability: Breathable membranes exhibit high moisture permeability, rapidly expelling condensation and preventing insulation dampness and failure
- Excellent Waterproofing: High hydrostatic pressure rating effectively blocks wind-driven rain, protecting building structures
- Vapor Barrier: Extremely low water vapor transmission rate prevents indoor humidity infiltration, avoiding condensation and mold growth
- High Tensile Strength & Durability: Reinforced base material resists tearing and punctures, suitable for harsh construction environments
- Easy Installation: Lightweight roll format allows simple laying and overlapping, significantly reducing construction time

FAQ

Q1: What's the difference between breathable membrane and waterproof tarp?

A1: Breathable membrane not only prevents water ingress but also allows internal water vapor to escape, preventing “sweating” and mold; conventional waterproof tarps only block water but do not allow vapor passage, leading to internal condensation.

Q2: On which side should the vapor barrier be installed?

A2: The vapor barrier should be installed on the inner side of the insulation layer (the warm side, i.e., indoors) to block indoor humidity from entering the insulation.

Q3: What is the service life?

A3: With proper installation and protective outer layer, service life reaches 20–50 years—comparable to the building itself.

Q4: Does winter installation affect performance?

A4: Material may stiffen at low temperatures. Install above 5°C if possible. If unavoidable, pay attention to adhesive tape bonding performance and preheat when necessary.

Q5: Can breathable membrane replace roof tiles?

A5: No. Breathable membrane serves as secondary waterproofing (secondary defense) and must be used in conjunction with primary waterproofing layers such as roof tiles or metal roofing.
