Application

To be used in conjunction with Ravatherm XPS X 300 SL for an inverted flat roof - a form of flat roof where the thermal insulation is placed above the waterproof membrane.

Description

Ravatherm XPS X MK is a water flow reducing layer (WFRL) consisting of a polyethylene geotextile, used in conjunction with Ravatherm XPS X 300 SL.


Features and benefits:

  • Water vapour-permeable.
  • Water-resistant.
  • Tear-resistant.
  • Uv stable - can be left exposed outdoors for up to four months.
  • Fire - melts and shrinks away from a heat source (unclassifiable as regards building regulations).
  • Temperature - retains flexibility and toughness down to -73°C, melting point is 135°C.
  • Excellent rot resistance making it ideal for insulating green roofs.
  • A WFRL is a critical component of an inverted flat roof, minimizing heat loss due to the rainwater cooling effect.
  • Ravatherm XPS X MK prevents rainwater from reaching the waterproofing layer, thereby reducing the rainwater cooling effect caused by rainwater flowing between the insulation and waterproofing membrane.
