Application

Can be laid on roofs designed for slopes with a minimum 1:100 towards the outlet. Suitable for refurbishment applications on flat or pitched roofs. Can be used on concrete roof decking, plywood WBP to BS 5268-2 and BS EN 636-3 and roofing Grade OSB to BS EN 300, Grade 3.

Description

Water attenuation blue roofing system for existing roofs that includes Protan BPX 1.8 mm thick roofing membranes, manufactured from PVC with a core of polyester reinforcement. To be installed as exposed roofing, allowing rainwater to accumulate to a predefined maximum level and be stored on the roof for a certain amount of time after rainfall. Water run-off is then gradually permitted into the into the building's drainage system before entering the drainage network. This avoids water overloading, which can result in flooding. Joint welds are carried out using hot air.


Features and benefits:

  • Can be laid on roofs designed for slopes with a minimum 1:100 towards the outlet.
  • Embossed surface provides a slip resistant texture.
  • Cost effective, using the existing roof surface area.
  • Can be used with or without insulation.
  • Additional stabilizers ensure the system is resistant to temperature, UV radiation and atmospheric contamination.
  • Controls water pressure, which helps to reduce floods and flood damage.
  • Can be used on both conventional and external drains.
  • SINTEF approved.
  • Suitable for refurbishment applications on flat or pitched roofs.
  • Membrane is manufactured from pliable PVC reinforced with knitted polyester, with stabilizers that 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.


Substrates:

Can be used on the following:

  • Concrete roof decking.
  • Plywood WBP to BS 5268-2 and BS EN 636-3, minimum thickness 18 mm.
  • Roofing Grade OSB to BS EN 300, Grade 3, and minimum thickness 18 mm.


Manufacturer recommends that at least one additional overflow is installed into the parapet for protection.
