Installation overview

  1. New metal-sheet roofs: weld wire mesh over the purlins, lay the insulation across the purlins, then fix the roof sheets
  2. Old or new buildings (fibre-cement or metal-sheet roofs): weld wire mesh under the purlins and lay the insulation between them
  3. Or tie wire over the purlins and lay the insulation across them, or tie wire under the purlins and lay it between them
  4. 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.
