General Application Method

1. In H1 zones 2 and 3 a vapour layer is laid upon the substrate. Depending on the project timetable, this layer can be left exposed to act as temporary waterproofing.
2. The Enertherm insulation is set out over the vapour barrier. The sheets are staggered in a brick bond fashion to prevent movement which could result in gaps in the insulation. The insulation is secured using screws with a purpose built flange. (Photo A)
3. A basesheet layer of Nuraply 3PV-SA is fixed over the insulation. This special sheet is designed specifically for adhering to the insulation and provides a complete watertight layer once installed. (Photo B)
4. A cap sheet of Nuraply 3P or Nuraply 3PM is welded onto the basesheet layer. The joints are welded to ensure a watertight solution. (Photo C)
