The G950 Weep Vent is used to drain lintels, cavity trays and to ventilate cavity walls, while the G951 Peep Weep provides a discrete, hidden solution to cavity wall drainage requirements.
The Manthorpe G950 Weep Vent is used to drain lintels, cavity trays and to ventilate cavity walls.
The product can be slotted between two bricks and mortared into position. It provides 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.
When used with the Manthorpe range of catchment trays the Weep Vent should be placed in the furthest corner away from the finished roof line.
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.”
