Airflow’s AIR950 dual purpose concealed/exposed weep vent can be slotted between two bricks and mortared into position. The vent has a baffled grill and a drip lip at each end which reduced the ingress of driving rain and wind. The weep vent has been designed to be wide enough not to be blocked by water droplets, but still able to stop large insects from gaining access. the inbuilt drip lip sheds moisture away from the brick face.
The Weep Vent should be spaced at no greater than 900mm centres to meet N.H.B.C guidelines, which state, “weep holes are recommended to be sited at every 450mm maximum with at least two per opening above all windows and doors.”
