Protan Prefabricated System - SE Membrane - Warm Roof Construction

Mechanically fixed, prefabricated PVC single-ply membrane roof system for warm roof constructions with unique, prefabricated rolls of membrane with secret-fix strips.

The PVC contains stabilizers, which provide fire resistance and make the product UV stable and resistant to both high and low temperatures. The anti-slip surface texture provides a significant safety factor when walked upon in wet weather.

Features and benefits:

• The system is suitable for large simple roofs in which 1000 mm wide rolls of membrane would traditionally be installed.
• The prefabricated rolls of membrane enable quick installation, with up to 70% reductions in onsite welding times.
• Suitable for new build and refurbishment applications with flat or pitched roofs.
• Protan SE membrane is manufactured from pliable PVC reinforced with knitted polyester. The PVC contains stabilizers, which provide fire resistance and make the product UV stable and resistant to both high and low temperatures. The membrane remains flexible at low temperatures, during installation and use.
• Protan SE membrane has a unique slip resistant texture.

Durability:

• Accelerated weathering tests and performance in service indicates that Protan SE 1.2 mm should have a life in excess of 40 years.
• SE 1.6/ 1.8 mm membranes may have a longer life expectancy.

Fire Resistance:

Tests indicate that

• A system comprising 0.7 mm profiled steel decking, 50 mm polyurethane insulation with an aluminium foil facing on the upper side and glass tissue facing to the underside and one layer of Protan SE mechanically fixed will be unrestricted.
• A system comprising 0.7 mm profiled steel decking, 0.21 mm thick vapour control layer, 90 mm foil-faced polyurethane insulation and one layer of Protan SE mechanically fixed can be classified under BS EN 13501-5:2005 as Broof (t4).
• A system comprising 0.7 mm profiled steel decking, a polyethylene vapour control layer, 150 mm foil faced Kingspan TR26 PIR insulation and one layer of Protan SE mechanically fixed can be classified under BS EN 13501-5:2005 as Broof (t4).
• A system comprising an 18 mm plywood deck, a polyethylene vapour control layer, 150 mm foil faced Kingspan TR26 PIR insulation and one layer of Protan SE mechanically fixed can be classified under BS EN 13501-5:2005 as Broof (t4).
