Application

  • Suitable for new-build and refurbishment applications on flat or pitched roofs.
  • For use as roofing on different kinds of substrate including concrete. Other substrates will be assessed on a project-specific basis by Protan's Technical Services Department.

Description

The Protan Vacuum System uses one-way air vents to suck the air out of the space between the Protan membrane and the substrate. This creates a vacuum within the space, which sucks the Protan membrane down to the substrate and holds it in place without the need for mechanical fixings or adhesives.

The system is suitable for both new-build and refurbishment projects. The roof substrate and the membrane’s perimeter fasteners must be airtight. In order to assess building suitability, it must be inspected and evaluated by a Protan Technical Services Manager.


Features and benefits:

  • Protan SE membrane is manufactured from pliable PVC reinforced with knitted polyester. The PVC contains stabilizers that provide fire resistance, make the product UV stable and resistant to high and low temperatures. The membrane remains flexible at low temperatures, during installation and use.
  • Protan SE membrane has a unique slip resistant surface texture, which provides a significant safety factor when walked upon in wet weather.
  • Average cost savings of around 20% when compared to an adhered system.


Durability:

  • Accelerated weathering tests and performance in service indicate that Protan SE membrane should have a life in excess of 40 years with mandatory maintenance.
  • Protan SE 1.6/ 1.8 mm membranes may have an even longer life expectancy.
  • The use of lighter colours helps to reduce surface temperature, which may improve the membrane's ageing performance.


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).


Performance:

  • Tensile strength (EN 12311-2): >1050 N / 50 mm.
  • Elongation at break (EN 12311-2): >15%.
  • Tear strength (EN 13210-2): 210 N.
