Applications
Highlights
- Roll, unfaced
- Helps with both heat and rain noise
- Three densities, two thicknesses
Installation overview
- New metal-sheet roofs: weld wire mesh over the purlins, lay the insulation across the purlins, then fix the roof sheets
- Old or new buildings (fibre-cement or metal-sheet roofs): weld wire mesh under the purlins and lay the insulation between them
- Or tie wire over the purlins and lay the insulation across them, or tie wire under the purlins and lay it between them
- Under concrete roof slabs: set anchors and string wire, or fix with insulation pins and washers, cleaning the pin positions first
Always follow the manufacturer's installation and safety instructions.
