1. Water resistance
Hydrostatic pressure resistance: ≥15kPa (EN 20811 standard), capable of withstanding strong wind and rain infiltration.
Joint sealing: A continuous waterproof layer is achieved through self-adhesive strips or welding processes.
2. Air permeability
Water vapor transmission rate (MVTR) : ≥1000g/m²/24h (EN ISO 12572), promoting the discharge of moisture inside the wall and preventing condensation and mold growth.
3. Durability
UV resistance: PE films with added UV stabilizers can be exposed outdoors for 3 to 5 years without aging.
Temperature adaptability: Operating temperature range -40℃ to 80℃, suitable for extremely cold or hot regions.
Chemical stability: Resistant to acid, alkali and salt spray corrosion, suitable for coastal or industrial area buildings.
