Jutatop WB LIGHT MEMBRANE FOR OPEN JOINTS FACADE SYSTEMS Economic UV resistant wall membrane max 3 cm PRODUCT DESCRIPTION JUTATOP WB LIGHT is manufactured by coating a polyester spunbonded nonwoven layer with a polyacrylic film to create a two-layer UV resistant weatherproof breathable wall membrane. ■ JUTATOP WB LIGHT is used for ventilated horizontal open joints facade systems. JUTATOP WB LIGHT is fixed directly onto a wall construction with no requirement for ventilation space from the bottom. ■ JUTATOP WB LIGHT is a lighter-weight wall membrane combining excellent weather resistance (rain and wind-resistance), extreme UV stability and high vapour permeability with favourable costs. This makes JUTATOP WB LIGHT particularly suitable for horizontal open joints facades applications, while respecting the economical aspect. JUTATOP WB LIGHT offers year-round protection in all weather conditions against leakages and water vapour condensation even in the case of partial exposure of JUTATOP WB LIGHT to external weathering throughout its whole lifetime. ■ JUTATOP WB LIGHT is available with double integrated tape upon request for easy-to-implement installations. ■ JUTATOP WB LIGHT is supplied in black colour, and it can be tailored to your requirements in regards to, print design and palletisation. ■ JUTATOP WB LIGHT is naturally mould and rot resistant. ■ JUTATOP WB LIGHT 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 JUTATOP WB LIGHT ensure all surfaces to be covered are firmly fixed, clean and smooth. ■ To install, JUTATOP WB LIGHT should be laid horizontally across the wall and fixed with non corrosive flat-headed nails or staples. 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. ■ JUTATOP WB LIGHT 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 JUTATOP WB LIGHT must be made over the counter battens only. Laps should be a minimum of 150 mm. ■ Laps 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. ■ JUTATOP WB LIGHT is designed for open joint facade systems with maximum 3 cm of open gaps and maximum 30 % of open area. However it is recommended to cover JUTATOP WB LIGHT with claddings without delay. © This is an indicative document, which does not substitute the installation guideline.
