Installing DrillVent couldn't be easier.

High level vents are located externally 200 – 225mm below the soffit or roof barge. Low level vents should be installed below the DPC where possible 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.

Step 1:

Identify the location at which you need to place the vent. A 25mm hole is cored typically at 750mm centres at both high and low levels. Advice in regulations or from guarantors should be followed.

Step 2:

The vent has been designed to be installed at a slight angle (2.5 degrees), 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 as to avoid any damage to the internal leaf, insulation or breather membranes.

Step 3:

Insert and align the DrillVent into the hole and tapped into place using a rubber mallet. DrillVent should finish flush with the wall surface.
