Wall breather membrane - reflective
A heat reflective membrane that helps to improve thermal efficiency by reflecting radiant heat in summer and reducing convective heat loss in winter. As a strong, water-resistant breather membrane with a metallized surface, it is suitable for use in any wall system that requires secondary protection from external moisture. The 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. It's airtight and water resistant, yet vapour-open, properties help to create an energy efficient construction that lasts the lifetime of the building.
