Wall Wrap MD (Medium Duty) by Trade Select

Trade Select Wall Wrap MD (Medium Duty) is a tough, breathable wall wrap that combines weather protection with vapour permeability for wall systems that need to stay dry and efficient. Ideal for use behind external cladding on two-storey homes or semi-commercial builds, this wrap is rated Class 4 for vapour breathability and allows moisture to escape while preventing external water and wind ingress. The medium-duty scrim reinforcement gives it superior strength compared to LD versions, making it perfect for exposed builds, renovations, and upgrades. Each roll covers 40.5 m² and installs easily on timber or steel frames.

Kingspan Alternative

Kingspan AIR-CELL Permishield 100
Both are breathable, non-reflective vapour-permeable wall wraps designed for more demanding applications behind cladding, offering improved durability and condensation management.
