With this processing technique, the uTHERM Flat Roof BG roof insulation boards are always installed in a crisscross pattern and in a single layer.
2-layer processing is not possible, due to the high temperatures.
5. Loose installation
The u THERM Flat Roof PIR M/BG/L/BGM insulation boards can only be applied without fasteners if the roofing and the necessary load are
installed immediately after the boards, and if the roofing can be sufficiently fixed to the edges of the roof. This also applies when terrace tiles
provide the necessary ballast load.
