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.
