1.5 m Roll Width
BSI Kitemark
Certificate type
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.
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.
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.
