Light Wall duty to AS\/NZS 4200.1:2017.\u003c\/p\u003e\n\u003ch3\u003eHighly permeable, by design\u003c\/h3\u003e\n\u003cp\u003eVapour 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.\u003c\/p\u003e\n\u003ch3\u003eNon-reflective, so simpler to detail\u003c\/h3\u003e\n\u003cp\u003eEmittance 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.\u003c\/p\u003e\n\u003ch3\u003eStrength\u003c\/h3\u003e\n\u003cp\u003eBall 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.
