Why Choose Wallint 50 Membrane?
Improve Airtightness Across the Structure
Wallint 50 Membrane helps form a continuous internal air barrier, reducing uncontrolled air leakage and improving overall building performance.
Enhance Insulation Efficiency
By limiting air movement within the structure, the membrane allows insulation to perform as intended and reduces heat loss.
Control Moisture Movement
The vapour control layer helps manage the passage of moisture from inside the building, lowering the risk of condensation within walls and roofs.
