1.5 m Roll Width
1.5 m Roll Width
A spun-bonded polyethylene geotextile, this vapour permeable waterpoof membrane is used as a ‘breather’ layer in inverted ballasted flat roofs and is available in 1.5 m or 3 m rolls.
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.
