DuPont™ Tyvek® Reflex
Improve Thermal Efficiency With a Heat Reflective Membrane
A Tyvek® Reflex heat reflective membrane helps to improve thermal efficiency by reflecting radiant heat in summer and reducing convective heat loss in winter.
DuPont™ Tyvek® Reflex
Tyvek® Reflex is a strong, water-resistant breather membrane with a metallised surface. It is suitable for use in any wall system that requires secondary protection from external moisture. This low emissivity membrane is particularly effective in lightweight wall construction such as timber or metal frame systems, and is also popular for masonry and internal insulation upgrades.
Successfully installed in the UK since 2002, Tyvek® Reflex is the first reflective breather membrane for thermal management. Its airtight and water resistant yet vapour-open properties help to create an energy efficient construction that is money saving and lasts the lifetime of the building.
