Description

A spun bonded polyethylene geotextile based upon Tyvek® by DuPont that is waterproof and vapour permeable

Features and benefits:

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 ProTherm XPS Inverted Roof Insulations or ProTherm Quantum PLUS+ Inverted Roof Insulation in an inverted roof, it reduces the rainwater cooling, reducing the required insulation thickness by 2%.
Certificates ISO 9001: 2008 Quality Management System, ISO 14001: 2004 Environmental Management System, EPD as per ISO 14025 and EN 15804.
