General Information

RAVATHERM XPS X MK Water Flow Reducing Layer is a spun bonded polyethylene geotextile based upon Tyvek® by DuPont that is waterproof and vapour permeable.

RAVATHERM XPS X MK Water Flow Reducing Layer replaces the usual separating layer laid between the insulation and ballast, prevented from reaching the waterproofing layer and almost completely eliminating the rainwater cooling effect.

When installed with RAVATHERM XPS X SL, RAVATHERM XPS X SL ULTRA or RAVATHERM XPS X 500/700 SL Inverted Roof Insulation in an inverted roof RAVATHERM XPS X MK Water Flow Reducing Layer reduces the rainwater cooling, reducing the required insulation thickness by 2%.

For use with appropriate Waterproofing Systems.
