Jutadach THERMOISOL WB NP MEMBRANE FOR OPEN JOINTS FACADE SYSTEMS UV resistant wall membrane max 3 cm PRODUCT DESCRIPTION JUTADACH THERMOISOL WB NP is manufactured by coating polyester nonwoven layer with a polyurethane film to create a two-layer UV resistant weatherproof breathable wall membrane. ■ JUTADACH THERMOISOL WB NP is used for ventilated horizontal open-joints facade systems. JUTADACH THERMOISOL WB NP is installed directly onto a wall construction with no requirement for ventilation space from the bottom. ■ JUTADACH THERMOISOL WB NP is a wall membrane combining excellent weather resistance (rain and wind-resistance), extreme UV stability and high vapour permeability. This makes JUTADACH THERMOISOL WB NP particularly suitable for horizontal open joints facades applications. ■ JUTADACH THERMOISOL WB NP is available in the width up to 3.0 m, this helps to minimize the amount of overlaps, splices and installation costs in general. ■ JUTADACH THERMOISOL WB NP offers year-round protection in all weather conditions against leakages and water vapour condensation even in the case of partial exposure of JUTADACH THERMOISOL WB NP to external weathering throughout its whole lifetime. ■ JUTADACH THERMOISOL WB NP is available with double integrated tapes upon request for easy-to-implement installations. ■ JUTADACH THERMOISOL WB NP is supplied in black colour, and it can be tailored to your requirements in regards to, print design and palletisation. ■ JUTADACH THERMOISOL WB NP is naturally mould and rot resistant. ■ JUTADACH THERMOISOL WB NP fully conforms to EN 13859-2. STORAGE ■ Rolls should be stored flat on a clean, level surface, and kept away from sunlight. ROLL SPECIFICATION WIDTH OF MEMBRANE * Other roll sizes are available upon request INSTALLATION ■ Prior to the installation of JUTADACH THERMOISOL WB NP ensure all surfaces to be covered are firmly fixed, clean and smooth. ■ To install, JUTADACH THERMOISOL WB NP should be laid horizontally or vertically across the wall and fixed with non-corrosive flat-headed nails or staples, within the overlap area preferably to minimise the amount of penetrations. In case of vertical installation all overlaps must be mechanically attached. Counter battens are then installed over the underlay, and fixed through. The cladding is fixed to counter battens, leaving space between the underlay and claddings for drainage and air ventilation. ■ JUTADACH THERMOISOL WB NP should be installed loose, flat and without wrinkles. Where possible avoid blockages that would otherwise prevent the free drainage of water. ■ Where possible the number of laps should be kept to a minimum by using full lengths of sheeting. If impossible, vertical connections of JUTADACH THERMOISOL WB NP must be made over the counter battens only. Overlaps should be a minimum of 100 mm. ■ Overlaps should be preferably sealed with integrated tapes. Simply peel off the liners and fix the overlaps applying manual pressure. Another option is usage of JUTATOP WB TAPE to seal the overlaps. Any penetrations or minor damages may be sealed by JUTATOP WB TAPE. ■ JUTADACH THERMOISOL WB NP is designed for open joint horizontal facade systems with maximum 3 cm of open gaps and maximum 30 % of open area. However it is recommended to cover JUTADACH THERMOISOL WB NP with claddings without delay. © This is an indicative document, which does not substitute the installation guideline.
