The WÜTOP Thermo ND/SK is a highly water-vapour-permeable, polyester-based roofing underlay with a monolithic membrane. It is installed directly on the heat insulation or decking of ventilated and non-ventilated pitched roofs. When combined with a WÜTOP vapour retarder/barrier and EURASOL adhesive tapes, it can be used to create modern airtight and windproof structures that comply with the EnEV (German Energy Saving Ordinance).
Perforation-proof
Self-seals around nail punctures on pressure-resistant surfaces (tested at the Fraunhofer Institute for Building Physics and Technische Universität Berlin)
Technology
Non-woven polyester with three-layer special coating and monolithic functional membrane with (SK) and without self-adhesive strips
Safety
Polyester is an extremely weather-resistant material, provides a high degree of protection against UV radiation and is temperature-resistant up to +150 °C / Even wet adhesive strips can be bonded reliably
Saves time and money
Self-seals around nail punctures saving huge amounts of time and money. Easy and fast installation due to integrated adhesive strips (SK)
According to the test certificate no. AZ 100204-3 from the Technical University of Berlin from 22.02.2010 and test reports nos. P6-135/2009; 136/2009 and 137/2009 from the Fraunhofer Institute for Building Physics – each based on DIN EN 13111; 2001-08 – the product is classified as nail-proof and resistant to driving rain.
Note:
In the test reports P-6-210/2014 (without nail sealing tape) and P-6-211/2014 (with nail sealing tape), both systems were tested. The Wütop Thermo ND/SK showed sufficient resistant to nail punctures.
The following construction-related conditions must be met:
- Secure counter-battens with 3.1x90 nails
- Install dry counter-battens. (S10, <20M%)
- No staples in the surface area of the strip; alternatively, these staple points can be sealed afterwards with a suitable adhesive tape.
