The Only Architect-Inspired Cavity Closer

Another innovative solution from DynexBuild, the new 20mm Architectural Cavity Closer is available in Graphite and Ivory to match cladding and soffit lining finishes.

The patented design hides the unsightly slots commonly associated with a drained cavity finish above eye level, meaning the aesthetics of the project aren't compromised. This also saves a disproportionate amount of time spent on masking these areas.

Be confident in the details with the only BRANZ appraised cavity closers on the market:

  • Hidden slots
  • Colour options
  • BRANZ appraised
  • CAD details available
  • Patent pending 
  • Made in New Zealand

This competition has now closed.
