Profiled Roof Overlay System

When to specify...

The Profiled EPS overlay system is primarily intended for refurbishing profiled sheet metal roofs or increasing the thermal performance of existing insulated cladding systems, bringing the construction up to current building regulation requirements.

The profiled insulation boards are manufactured to order and samples are produced to ensure that the profiles match the existing roof sheets. U-values are calculated using the average thickness of the profiled insulation board. The system with Thermofol PVC membrane achieved European Class Broof(t4) for fire performance.

1 Single ply membrane Thermofol or Thermoplan	Thermofol PVC single ply waterproofing membrane used to seal the insulation. Thermoplan FPO single ply waterproofing membrane used to seal the insulation.
2 GV120 when Thermofol PVC membrane is specified	Glass separation fleece used only when Thermofol PVC membrane is specified.
3  Profiled EPS insulation	Expanded polystyrene insulation cut and shaped to match the profile of the sheet metal roof.
