Trade Select VapourTech Wall is a Class 4 vapour permeable residential wall wrap, 0.45 mm thick, stocked in a 1500 mm x 30 m roll covering 45 m² and a 3050 mm x 30 m roll covering 91.5 m². Light Wall duty to AS/NZS 4200.1:2017.
Highly permeable, by design
Vapour permeance is 3.764 µg/N·s, which is high even for a Class 4 membrane. The wall can dry outward readily, while the wrap still works as a water barrier to AS/NZS 4201.4 and as an air barrier. In a residential wall that is usually what you want, because the moisture load comes from inside the house.
Non-reflective, so simpler to detail
Emittance is 0.58 and 0.56 on the two faces, category NN. It does not work by reflection, so there is no air gap to preserve and it can sit directly against the frame. It is also non-conductive, unlike a foil wrap.
The 3050 mm roll
At just over three metres wide it runs a full storey in one piece, so the horizontal join disappears and there is one less lap to tape. On a long elevation that is the difference the wide roll buys, and it is the reason to pay more per roll for the same square metre rate.
Strength
Ball burst 215 N against a 200 minimum, edge tear 189 N machine direction against a 45 minimum, and 0.0% shrinkage against a 0.5% limit. Flammability classification Low.

A Class 4 wrap lets the wall cavity dry outwards, which matters most in the cooler and mixed climate zones where condensation risk sits inside the frame.

Fitting notes
Install to AS 4200.2, printed face out, with joints lapped so water runs over them. Being non-reflective it does not need an air gap behind it. The 3050 mm roll runs a full storey in one piece and removes the horizontal join. Keep it out of contact with wet cement and mortar while the cladding goes on. Store rolls undercover in the pack until you need them.
Figures are taken from the Ametalin technical data sheet for VapourTech Wall, document APM-45763-1, and the Trade Select sheet TPM-24124-1 for the same product.
