Ecoply were asked to supply and install a single ply warm roof to this extension in Crawley. We were asked to provide a 25year manufacturers warranty. To achieve this we used Protan’s Se1.8mm standard overlap membrane and uprated the fixings to stainless steel.

We first laid out the vapour control layer and ensured all laps/joins were taped and sealed. Then we installed the PIR insulation boards, before the Velux flat roof lights were dropped into position.

Then the Protan single ply system was installed, including reinforced Protan edge trims to the eaves, verges and also chased and sealed against the brickwork. The carefully heat welded overlaps and cover strips ensure a permanent weathertight seal that will last a very long time.
