{"product_id":"trade-select-wall-wrap-xr-micro-perforated-hd","title":"Trade Select Wall Wrap xR Micro-perforated HD","description":"\u003cp\u003eTrade Select Wall Wrap xR Micro-perforated HD is the wall wrap Ametalin built for brick veneer and drained cavity walls. It is vapour permeable and double sided reflective at the same time, which is an unusual combination and the reason it costs more than a plain breather wrap.\u003c\/p\u003e\n\u003ch3\u003ePermeable and reflective together\u003c\/h3\u003e\n\u003cp\u003eThe micro-perforation pattern gives Class 4 vapour permeance at 1.450 µg\/N·s, so indoor water vapour can pass out into the cavity rather than condensing inside the wall. Both faces are reflective, 0.05 anti-glare and 0.03 foil, so the cavity between the frame and the brick leaf turns into a reflective air space. Ametalin declare RT 1.72 winter for a brick veneer wall with the wrap alone, and RT 3.40 winter with an R2.7 batt added.\u003c\/p\u003e\n\u003ch3\u003eNot a water barrier\u003c\/h3\u003e\n\u003cp\u003eRead this part carefully. It is classified Non-Water Barrier. Perforating a membrane to let vapour out also lets liquid water through, so this belongs behind a masonry leaf or a drained cavity where the outer skin sheds the rain. It is not the wrap for a direct fixed cladding wall.

It is an air barrier, and flammability index is Low, at or below 5, with compliance to AS 3959-2018 for all BALs.\u003c\/p\u003e\n\u003ch3\u003eOn site\u003c\/h3\u003e\n\u003cp\u003eKeep the cavity clear so the reflective faces have air in front of them and the drainage path stays open. The wrap is electrically conductive, so keep it clear of wiring. Install to AS 4200.2.
