Trade Select® Wall Wrap MD Micro-perforated. Product Code: TSMD-B. Vapour permeable reflective wall insulation for use in brick veneer and drained cavity wall systems in residential and commercial buildings in Climate Zones 2–8.
Trade Select® Wall Wrap Micro-perforated is a Medium Duty, Vapour Permeable wall wrap designed for use in brick veneer and drained cavity wall systems to reduce the risk of interstitial condensation. The reflective foil side provides extra R-value when installed facing an air cavity, and the multi-layer structure provides superior strength, flexibility and durability.
Classified as Class 4 Vapour Permeable, a dense pattern of micro-perforations allows water vapour to escape from the wall structure. Trade Select® Wall Wrap Micro-perforated also acts as a barrier to air, radiant heat and dust penetration.
It is a flexible four-layer product made with a combination of anti-oxidant UV-stabilised woven polypropylene, 97% reflective aluminium foil, and fire-resistant polymer adhesive, backed by a UV-stabilised polymer flood coat. Products are pre-shrunk during the manufacturing process.
Features
- Micro-perforated to Class 4 Vapour Permeable
- Strong and light weight
- Air Barrier
- Low Flammability, suitable for all BALs in bushfire-prone areas
- 97% reflective
Application
Class 4 Vapour Permeable wall wraps are not recommended for wet tropical climate zones.
