Enertherm PIR Insulation Boards

Enertherm PIR is a 100% CFC, HCFC or HFC-free insulation board with a rigid polyisocyanurate foam core, clad on both sides with a multi-layer gas-tight aluminium complex. Enertherm PIR insulation has a high efficiency per m², so compared to other insulation materials (such as EPS, XPS and Rockwool), a higher insulation value is achieved with a thinner board.

Using Enertherm PIR across the entire flat roof surface, the R value of the system is higher than the R value of the PIR. In comparison, using lofted insulation between the rafters the R-value of the system is actually lower than the insulation R value due to thermal bridging.

Key Features
  • Improved insulation with no thermal breaks
  • Cross ventilation of ceiling void not required
  • Can be retrofitted on existing buildings
  • High compressive strength
  • Lightweight and easy to handle on site 
  • Optimises energy efficiency
  • 20 year product warranty
  • BRANZ Appraised
Scope of Use

Enertherm boards can be installed over plywood, concrete or metal substrates, on new or existing buildings and on flat roofs with a minimum 1:30 slope.
