Tyvek® AirGuard® Smart is an innovative air and vapour control layer which protects structures against environmental damage by adapting to various moisture conditions and regulating the humidity in building elements. The design of Tyvek® AirGuard® allows for faster evacuation of built-in humidity in new construction elements. It also means avoiding humidity infiltration from living spaces into the building’s structure, minimising the risk of expensive damage from damp and mould. What are the benefits of the DuPont Tyvek® AirGuard® Smart Air and Vapour Control Layer? Reduced drying out time. Adapts to various moisture conditions. Durability, health and longevity of buildings. Greater energy efficiency. Additional drying capacity for unplanned humidity infiltration. Enhanced interior comfort. Developed for both new build and refurbishment projects. Can be installed in conventional dry-lining applications from the inside, but also from the outside when carrying out renovation work Specification Material: Tyvek® with polymeric coatingRoll size: 1.50m x 50mWeight: 7 kgReaction to fire: EMass per unit area: 92g per m2Temperature resistance: from -40 °C to 80 °CMaximum tensile force (MD/XD): 380/380 N/50mmResistance to tearing (MD/XD): 70/65 NAir permeability (ISO 5636/5): 2000 s
