Drill Vent

Installation Advice

High level vents are located externally between 200–225mm below the soffit or roof barge
Low level vents should be installed at a minimum of 125mm below the DPC at ground level. At this level, it doubles as a drain for the cavity as well as a vent if the cavity is bridged or closed at intermediate floor levels. Cavity venting and drainage should be provided above and below the floor plate.
Identify the location at which you need to place the vent, where a 25mm hole is typically cored at 750mm centres, at both high and low levels. Advice in regulations or from guarantors should be adhered to
The vent has been designed to be installed at a slight angle of 2.5° to minimize any wind-driven rain entering the cavity, therefore, the hole is drilled through the external leaf with the drill inclined slightly upwards. It is recommended to use a drill with a depth setting in order to avoid any damage to the internal leaf, insulation or breather membranes
Insert and align the Drill vent into the hole and tap into place using a rubber mallet, the drill vent should be flush with the wall surface
