Protan Prefabricated Sheet

Protan prefabricated sheets are particularly suitable for buildings that require rapid completion of the work. These sheets can be installed quickly over large areas, and welding on the roof is reduced considerably. Prefabricated sheets are also ideal for buildings subject to high wind-uplift forces.

Prefabricated Protan PVC single-ply membranes are ideal for large, simple roof plans that would traditionally be waterproofed using standard rolls of Protan SE membrane. Prefabricated membranes enable large areas of Protan membrane to be installed rapidly by reducing on-site hot-air welding operations by up to 70%. Prefabricated Protan membranes are manufactured off-site, with secret-fix strips factory-welded to their reverse side by high frequency welding technologies. The secret-fix strips are spaced at regular centres, usually 1.00m to simulate 1.00m-wide rolls installed in a Protan Standard Overlap system, however the spacing can be reduced to account for high wind uplift pressures. Prefabricated membranes significantly reduce the volume of membrane required, as the number and width of overlaps between adjacent rolls of membrane is minimised.
