Insulation

ProTherm XENERGY MinK

DESCRIPTION

ProTherm XENERGY MinK Water Flow Reducing Layer is a spun bonded polyethylene geotextile based upon Tyvek® by DuPont that is waterproof and vapour permeable.

ProTherm XENERGY MinK Water Flow Reducing Layer replaces the usual separating layer laid between the insulation and ballast, prevented water from reaching the waterproofing layer and almost completely eliminating the rainwater cooling effect.

When installed with ProTherm Quantum inverted roof insulation in an inverted roof ProTherm XENERGY MinK Water Flow Reducing Layer reduces the rainwater cooling, reducing the required insulation thickness by 2%.

Available in 100m roll length , ProTherm XENERGY MinK Water Flow Reducing Layer is for use with inverted roof waterproofing such as PermaQuik PQ6100, EshaFlex, EshaUniversal and ParaFlex.

For a comprehensive NBS J31 specification contract Radmat Building Products.

APPLICATION

Lay ProTherm Quantum inverted roof insulation boards.

Loose-lay ProTherm XENERGY MinK Water Flow Reducing Layer over the insulation, at right angles to the slope.

Overlap next sheet over the previous by 150mm (laps running down the slope). If the depth of the aggregate ballast is to be kept to a maximum of 50mm deep then 300mm laps are required.

At upstands and penetrationsProTherm XENERGY MinK Water Flow Reducing Layer should be turned up to finish above the surface of the ballast.
