Tyvek® Reflex
| Tyvek® Reflex is a vapour open underlay with a metallised surface that reflects radiant heat in summer and helps to reduce heat loss in winter. It can be used in timber frame walls as well as metal frames, masonry and internal insulation upgrades. The low emissivity surface (0.12) results in a highly reflective membrane (88%) for an improved thermal comfort and an enhanced airtightness of the construction. |
