Ravatherm XPS X MK is a water flow reducing layer
(WFRL) which should be used in conjunction with Ravatherm XPS X 300 SL inverted insulation. A WFRL is a critical component of an inverted flat roofing system, and minimises heat loss due to rainwater cooling.
Key Features
Reduces the volume of rainwater reaching the roof’s inverted insulation layer
Reduces the rainwater cooling effect, allowing greater thermal efficiency of the inverted insulation
Easy to install
