+44 (0)1925 658001 www.protan.co.uk
Application

Suitable for new build and refurbishment applications on flat or sloped roofs for warm roof constructions.

Description

Features:

  • Suitable for new build and refurbishment applications on flat or sloped roofs.
  • Designed to be fully adhered using a moisture-curing polyurethane adhesive.
  • Manufactured from pliable PVC reinforced with knitted polyester, with a polyester fleece laminated to the underside.
  • The PVC contains stabilizers, which make the product UV stable, flame retardant and resistant to both high and low temperatures.
  • Membrane remains flexible at low temperatures, during installation and use. However, the PU adhesive should only be applied when the air temperature is above +5ºC.
  • Unique anti-slip surface, which provides a significant safety factor when walked upon in wet weather.

Substrate:

  • 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 Board to BS EN 300, Grade 3, 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.

Durability:

Accelerated weathering tests and performance in service confirm that satisfactory retention of physical properties is achieved. All available evidence indicates that Protan EX-A membrane should have a life in excess of 40 years with mandatory maintenance.

Performance:

  • Tensile strength (BS EN 12311-2:2000): ≥1,100 N/50 mm.
  • Elongation (BS EN 12311-2:2000): ≥15%.
  • Tear strength (BS EN 13210-2:2000): ≥300 N.
  • Resistance to puncturing by static loading (BS EN 12470:2001): ≥200 N.
  • Resistance to puncturing by impact (BS EN 12681:2006, at 23ºC): ≥700 mm.
  • Foldability at low temperatures (BS EN 495-2:2001): ≤-25ºC.
  • Peel resistance of joints (BS EN 12316-2): ≥ 150 N/50 mm.
  • Shear resistance of joints (BS EN 12317-2): ≥1000 N/50 mm.
  • Hail resistance (BS EN 13583): ≥17.
  • Water vapour resistance, µ (BS EN 1931): 15000.

Fire Resistance:

  • Achieved a BROOF (t4) rating when classified in accordance with BS EN 13501-5:2005 and tested in accordance with DD CEN/TS 1187:2012 Test 4. (Tested system comprised an 18 mm plywood deck, polyethylene vapour-control layer, 140 mm thick EcoTherm tissue-faced insulation and one layer of Protan EX-A fully adhered to the insulation using Protan ProBond moisture-curing adhesive.)

Properties of waterproof membrane:

– Protan EX-A 1.5 mm Membrane:

  • Thickness: 1.5 mm + fleece.
  • Membrane weight: 1.75 kg/m².
  • Fleece weight: 180 g/m².
  • Roll width: 2 m.
  • Roll length: 20 m.
  • Unique slip resistant texture.

Air Vapour Control Layer (recommended):

– Protan PE Air Vapour Control Layer:

  • Thickness: 0.2 mm.
  • Colour: Blue.
  • Water vapour transmission: >78 m (Sd value), to BS EN 1931.
  • Installation: Loose lay and overlap all side and end laps by minimum 150 mm and seal with double-sided mastic tape. Tape dimensions; 1.5 mm x 60 mm.
  • Insulation must be mechanically fixed.

– Protan Self-Adhesive Air Vapour Control Layer:

  • Thickness: 0.6 mm.
  • Colour: Black/Foil Top Surface.
  • Water vapour transmission: >1,500 m (Sd value), to BS EN 1931.
  • Installation: Apply Protan VCL primer. Lay membrane and overlap all side laps by 60–80 mm and all end laps by at least 150 mm. Apply pressure evenly.
  • Insulation can be mechanically fixed or adhered.

Application:

Suitable for new build and refurbishment applications on flat or sloped roofs for warm roof constructions.
