Trade Select® 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® Micro-perforated 
also acts as a barrier to air, radiant heat and 
dust penetration.                                                                Product Sizing: 1350mm x 30m                                                            Quantity: 1 Roll                                                                                   Coverage Per Pack: 40.50m2
