Durable Protection for Rainscreen Cladding Systems
Where there is a risk of moisture penetration through the insulation and internal layers, a protection membrane behind the insulation is advised.
Rainscreen cladding systems differ from other wall constructions, as although the membrane is still fixed directly to the structure, it is situated behind the insulation. The material to specify is dependant on the risk of condensation at this interface, determined in the main by the temperature.
Permanent protection for open and ventilated rainscreen cladding
Modern open and ventilated rainscreen claddings offer great design opportunities for architects and builders alike. Open and ventilated rainscreen cladding systems are constantly exposed to the elements, so it is essential to fit a secondary membrane that can protect the underlying structures long-term from air, moisture and UV radiation.
Developed specially for open-jointed rainscreen cladding systems, Tyvek® UV Facade is a protective membrane that bears the CE mark for these applications – your guarantee of full conformity with the rigorous EU directive for construction products.
Meeting the Ageing Test
To obtain its CE mark for open rainscreen cladding systems, Tyvek® UV Facade had to resist 5,000 hours of artificial ageing by exposure to UV radiation, followed by 90 days’ exposure to temperatures of 70°C. By comparison, CE requirements for standard wall/roof applications specify just 336 hours of UV exposure.
Tyvek® UV Facade is wind- and watertight, yet vapour-open. Designed for open and ventilated rainscreen cladding systems in timber, metal, stone and other materials, it is extremely lightweight, flexible and easy to install.
Together with DuPontTM AirGuard® Control, Smart or Reflective vapour control layers, Tyvek® membranes create a complementary building envelope solution that manages moisture, is suitable for rainscreen cladding systems, and supports optimal energy efficiency.
Our full range of DuPont tapes and accessories works seamlessly with all these products to help you achieve better seals – and even greater energy efficiency.
