Installation Options

International best practice is to place the insulation on top of the roof substrate. In H1 zones 2 and 3 areas, a vapor barrier is installed before laying the insulation and fixing it with screws. The entire system is encased by two layers of bituminous membrane. This method promotes an R-value that is consistent across the entire roof envelope.

The system can be installed on plywood, concrete or metal substrates, on new or existing buildings and on flat roofs regardless of their slope.

The most cost effective method in a new build is with the Nuratherm profile metal tray - NMP 900. a purpose designed metal tray system in conjunction with Dimond Roofing. This lightweight construction method is much quicker and easier to install than plywood. Using this system, with spans up to 2,400mm, the entire build is achieved for less than a traditional membrane roof system. In addition, it helps with the build process as the NMP900 keeps the building dry from day one, and will not absorb moisture during construction.

All Nuratherm details have metal tray as an option.
