The WÜTOP Thermo ND Plus is a highly vapour-permeable polyester-based underlay membrane and roof protection film with a special coating. It is laid directly on the heat insulation or formwork of ventilated and non-ventilated pitched roofs.
Secured against perforation in accordance with ETA-17/0206
Self-seals around nail punctures on pressure-resistant surfaces (tested at the Fraunhofer Institute for Building Physics).
Technology
Polyester fleece with special coating
Safety
Polyester is an extremely weather-resistant material, offers excellent resistance against UV radiation, and is temperature resistant up to 120°C. The special coating is non-slip and can be securely bonded.
Saves time and money
Self-seals around nail punctures saving huge amounts of time and money. Easy and fast installation thanks to integrated adhesive strips.
Special version for slate
Suitable as a preliminary covering for slate roofs according to German Central Association of the Roofing Trade.
Please note the installation instructions for this product.
European technical assessment ETA-17/0206
UDB/USB
Meets the requirements of the ZVDH (German Central Association of the Roofing Trade) product data sheet for class UDB/USB
Secured against perforation in accordance with ETA-17/0206
In accordance with the test certificate of Technische Universität Berlin and the test reports nos. P-06-186-2015 and P-06-187-2015 of the Fraunhofer Institute for Building Physics - in each case, based on DIN EN 13111; 2001-08 - the product may be classified as perforation-proof (nail-proof) and resistant to driving rain as defined by these test reports. Note: Both systems were tested for test reports P-6-186-2015 (without nail sealing tape) and P-6-187/2015 (with nail sealing tape). The Wütop Thermo ND Plus has demonstrated sufficient resistance to nail punctures. The following construction-related conditions must be met:
- Fasten counter battens (30/50) with min. 3.1 x 90 nails (smooth) or 2.8 x 80 (grooved)
- 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.
