With 30 - 35% of heat lost through the roof of an uninsulated house it is clear that roof insulation is critical to an energy efficient building.
Enertherm PIR insulation has the highest efficiency per m². This means that, 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.
PIR insulation has very high compressive strength. Combining this with the excellent R-values of the aluminum faced Enertherm PIR boards makes for the ultimate flat roof insulation.
Enertherm boards are lightweight and easy to hand on site. The boards can be installed over plywood, concrete or metal substrates, on new or existing buildings and on flat roofs regardless of their slope.
