Traspir Metal & 3D mats for metal tray/standing seam roofs
Ideally suited for under metal tray/standing seam roofing, provides water/airtightness with vapour permeability and with micro ventilation layer between roof cladding and rigid substrate underneath.
Prevents moisture build-up PLUS reduces heat transmittance into the rigid sheathing, further reducing material and lifecycle stress. Increases thermal inertia and thus reduces energy requirements for summer cooling.
Certified Noise Reduction
The 3D mat incorporation guarantees reduction in airborne and heavy rail noise. Values tested and certified.
Protective Felt
The breathable membrane with 3D grid includes a fifth layer that blocks impurities and improves ventilation.
High Density 3D Grid
The 3D mat has high mechanical strength and is also appropriate for aluminium sheet metal..
