IINDUSTRIAL GRADE
- Used in the roofing system of factories and warehouses involving steel roof structure, PVC straining wires and steel battens.
- The PVC straining wires should run above steel battens where the Scrim Facing Insulation is secured to the PVC straining wires.
- The product should be laid vertically in the same direction as the straining wires with a 150mm overlap. It is recommended that the straining wires are spaced at 350mm intervals with the first straining wire secured at 75mm from the gable end.
- It is important that the product is laid tight against PVC straining wires and is secured using nails, staples or double-sided tape. Please allow for extra overlap at bottom and apex of the roof.
- For industrial application, it is advised that this product is installed by a licensed contractor to improve the effectiveness of product regarding fire, waterproofing, dust and thermal insulation.
