Overview
The breather version of the Medium Duty wall wrap.
ShieldFlex MD Breather Wall Wrap is a Medium Duty single-sided reflective wall wrap, perforated so water vapour can move outward through the wall. It is classified Class 3 Vapour Permeable, and carries the same reflective foil face and woven construction as the standard MD wrap.
Same Medium Duty construction as the standard MD wrap, perforated so the wall can breathe. Choose between the two on whether the wall design needs vapour to move outward or to be stopped , if you are unsure which the specification calls for, send it through and we will check it.
