Denpur Roof Deck Membrane

(1-2 mm)

Cold applied waterproofing membrane, with enhanced crack bridging properties for existing roof decks exposed to light pedestrian traffic. Can be installed with a UV protective coating to avoid discoloring from the sun.







 

Benefits

  • High Abrasion Resistance
  • Adhesion to all horizontal and vertical surfaces
  • Risk free installation
  • Reduces inside temperature
  • Heat reflective
  • Increased dynamic crack bridging class B4.2 at -20°C
  • Anti-slip properties for pedestrians and vehicles
  • Seamless application
  • Improves the efficiency of roof installed solar panels
  • No open fire during installation
  • Expected lifetime more than 30 years
  • Available in many colours
  • Application temperature from 5°C (open to traffic after 24 hours)
  • Chemically resistant to oils, petrol, diesel and de-icing salt
  • Green technology based on renewable raw materials
  • Reduces carbon footprint

Applications

A weatherproof very flexible and durable roof deck membrane with enhanced crack bridging properties. Due to the excellent bonding properties of the PU binder, the membrane is an excellent solution for the renovation of older bituminiuos roofs. If required the membrane can be protected with a UV resistant topcoat to avoid discoloring from the sun.

Scope of use

  • Roof decks

Application conditions

  • Temperature 10ºC to 30ºC, best 15 to 25ºC, max. moisture content in the substrate 5% by weight.

Appearance

  • Denpur Roof Deck Membrane is a coloured smooth flexible waterproofing membrane.

Temperature Resistance

  • Denpur Roof Deck Membrane is resistant to temperature cycles up to 90ºC dry heat and 80ºC. wet heat. Extended periods at these temperatures and above will make material susceptible to chemical attack and abrasion wear.

Life Expectancy

  • more than 30 years
