DuPont Tyvek UV Facade is specifically designed for long-term UV and moisture protection in open and ventilated rainscreen cladding systems. DuPont Tyvek UV Facade is the next generation in lightweight advanced protective membranes. Its proven track record of exceptional moisture management, high vapour permeability and durability makes it the superior protection solution for rainscreen cladding. Tyvek UV Facade is water resistant, vapour-permeable and windtight, and designed for long-term performance, coming with a 10-year product warranty from DuPont for joint widths of up to 3cm. Facades with open rainscreen cladding offer new design options, but the insulation and structure still require effective, lifelong protection from the harmful effects of the elements - including moisture, heat and UV radiation. Certification Tyvek UV Facade is a protective membrane for open-jointed cladding systems and carries the CE marking, certifying full conformity with the European Unions rigorous construction products directive. To obtain the CE marking for open cladding use, the membrane has to resist an articial aging by permanent UV radiation of 5000 hours (for a standard wall/roof application it is 336 hours). Features Proven long-term UV resistance (to date the only membrane with publicly available CE marking for open cladding use). For open joints of up to 3cm. 10-year product warranty for joint width of up to 3cm. Wind-tight, water-tight but vapour-open. Suitable for open or ventilated cladding in timber, metal, stone and other materials. Extremely lightweight, flexible and easy to install. Can be left uncovered for up to 4 months while retaining full performance warranty.
