Key features & benefits
The Government and New Zealand consumers are demanding energy efficiency is designed into modern buildings. And with 30-35%1 of heat going through the roof in an uninsulated house, roof insulation needs to be a focus during a building’s design.
Higher standards requires a complete rethink about how we construct our buildings. When it comes to flat roofs, international best practice is to use insulation as part of the flat roof system.
The Nuratherm system puts the insulation above the substrate, completely enclosing the roof area with a highly efficient insulation blanket. Nuralite has sourced from Europe the most effective product available and combined it with our respected waterproofing products to create the Nuratherm insulated flat roof system.
-
The most effective way to insulate a flat roof - improved insulation, with no thermal breaks.
- Less timber may be required as the rafters can be reduced to the minimum engineering requirements. There is no need to accommodate lofted insulation products and ventilation cavities
- No cross-ventilation of ceiling void required.
- Roof structure less susceptible to the effects of solar gain and thermal movement as it is insulated from outside temperature extremes
- A clear ceiling space is created providing ample space for running cables, installing downlights or speakers.
- Can be retro fitted on existing buildings to increase their energy efficiency
The Nuratherm boards are designed to be fastened to plywood, concrete or metal tray decks.
Nuralite has partnered with Dimond roofing to create the Nuratherm profiled metal tray deck. This is the optimal flat roof system as it is cost effective (similar to traditional cold roof system), quick and easy to install, suitable, watertight and warm.

Clause H1 will produce challenges for Architects creating contemporary styled homes.
Extensive use of glass walls will necessitate the use of calculation or modeling methods. As double glazing leaks heat, higher R-valued roof insulation will be vital to reach acceptable levels of thermal resistance for the entire building.
Slim roof profiles may be lost using traditional techniques as structural elements will need to be taller to accommodate thicker insulation in the ceiling. Warm roof design addresses these concerns. Additional sheets of insulation can be installed on the roof deck to improve the building's thermal design, but the slim lines remain as overhanging gutters are left uninsulated.
