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.
