Where to use Nuratherm Warm Roof system?

Where to use Nuratherm Warm Roof system?

The Nuratherm system puts the insulation where it should be, above the substrate, to completely enclose the roof area with a highly efficient insulation blanket. With 30 – 35% of heat lost through the roof of an uninsulated house, Nuratherm insulated roof systems optimizes energy efficiency in flat roof properties.

Why use Nuratherm on the outside of the structure?

Why use Nuratherm on the outside of the structure?

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, energy is wasted using lofted insulation between the rafters as R-value of the system is actually lower than the insulation R value due to thermal bridging.

What substrate does it need to be installed on?

What substrate does it need to be installed on?

The system can be installed on plywood, concrete or metal substrates, on new or existing buildings and on flat roofs regardless of their slope. By choosing to use the Dimond NPM900 metal tray as a substrate the entire roof system may be installed for less than a traditional flat roof system.
