Certificate type
Mechanically fixed PVC single-ply membrane water attenuation blue roofing system for warm roof constructions.
Application
- Can be laid on roofs designed for slopes with a minimum 1:100 towards the outlet.
- Suitable for new build and 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, profiled galvanized steel deck, roofing Grade OSB to BS EN 300, Grade 3 and profiled aluminium deck.
Description
Water attenuation blue roofing system for new and existing roofs that includes Protan BP 1.8 mm thick roofing membranes manufactured from PVC with a core of polyester reinforcement.
The product is 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 welding is carried out using hot air.
Features and benefits:
- Embossed surface that provides a slip resistant texture.
- Cost effective, using the existing surface area of the roof.
- 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 new build and refurbishment applications on flat or pitched roofs.
- Membrane is manufactured from pliable PVC reinforced with knitted polyester and contains 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;
- Profiled galvanized steel deck, minimum recommended thickness 0.7 mm to BS EN 10147 Fe E280G Z275;
- Roofing Grade OSB to BS EN 300, Grade 3, and minimum thickness 18 mm;
- Profiled Aluminium deck, minimum recommended thickness 0.9 mm to BS EN 485-1/ 2/ 3/ 4:1995 and BS EN 1999-1-4:2007.
Manufacturer recommends that at least one additional overflow is installed into the parapet for protection.
