1. Wall system
External wall insulation layer protection
It is laid on the outside of insulation materials (such as rock wool, EPS board) to prevent rainwater from seeping in and at the same time expel the moisture inside the insulation layer.
In combination with external curtain walls or coating systems, enhance the energy efficiency of the walls (such as passive houses and near-zero energy buildings).
Moisture-proof for wooden structures
It is used for wooden frame walls to prevent moisture from eroding the wood and extend the building's lifespan (common in North America and Northern Europe).
2. Roof system
Waterproof and breathable layer for pitched roof
It is laid under the roof tiles or metal plates to prevent rainwater from seeping back and to expel the moisture in the roof interlayer at the same time.
In combination with ventilation design, reduce the roof temperature in summer (such as the cold roof technology in green buildings).
Moisture-proof isolation for flat roofs
As the base layer of the waterproofing membrane, it prevents the moisture in the concrete base from rising and avoids bulging and cracking.
3. Special scenarios
Underground engineering: Moisture-proof layers for tunnels and basements to resist groundwater infiltration.
Metal roof: Reduce the contact between metal and moisture to prevent rust.
