The 70mm Bushfire Weepa for brick weep holes is a shortened version of the High Performance Bushfire Weepa. The patented grate is designed so that under extreme heat from bush fires it does not melt but chars and retains its structural integrity. The stainless steel mesh is retained in situ protecting the cavity from fire brands and sparks. Mesh specifications: T304 grade stainless steel woven mesh, wire aperture 0.415mm, wire diameter 0.22mm.

The High Performance Bushfire Weepa comes pre-assembled and is installed into the brick weep holes by the bricklayer. It can then be adjusted by the renderer who uses it as formwork to achieve neat and beautiful finishes.

After painting and clean up the mortar guard is removed for attractive, bushfire and vermin proof airflow and drainage.
