WEEP VENT BUFF

Packed: 50

RVWVSBU

Used to drain lintels, cavity trays and to ventilate cavity walls - provides 220mm² ventilation airflow
Can be slotted between two bricks and mortared into position to provide an unobtrusive ventilation point for the cavity behind
The vent has a baffled grille to prevent the ingress of driving rain and wind whilst incorporating an insect grille and drip lip
This grille is sized to keep out large insects but is wide enough that it will not be blocked by debris, paint or water droplets
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."
