Bradford Thermoseal® Breather Class 4 Wall Wrap
Bradford Thermoseal Breather Class 4 is a light-duty, perforated breather wrap with a single-sided reflective foil for residential and commercial brick veneer walls in Climate Zones 2-7 and bushfire-prone regions (BAL 12.5-FZ). This Class 4 vapour permeable wall wrap lets moisture escape so the cavity can dry, supporting insulation performance and helping protect framing.
Also suitable for cavity masonry (double brick) with a drained gap. For reduced glare on bright sites, choose Thermoseal Breather Class 4 XP, which adds a semi-reflective antiglare face.
