DrillVent is a new patented cavity venting system that not only solves the problems associated with the use of weep vents for cavity venting in timber framed buildings, but gives the added assurance that the cavity is suitably ventilated and drained.

DrillVent is retrospectively installed during the completion stage of the external wall. Concerns associated with the use of traditional weep vents for venting cavities are eliminated, ie. inadequate venting and insufficient drainage. With DrillVent, you are confident that the cavity is correctly ventilated and drained.

The slatted louvers are specifically designed to baffle direct blown wind. They are angled and spaced to promote the drying of condensation and rain-saturated outer leaf brick or blockwork whilst preventing the ingress of large insects. Drillvent is an ideal solution for the retro-fitting of vents that have simply been left out, become damaged or blocked during the construction process.

The circular design allows for efficient ventilation and is quick and easy to install. It has been engineered to be UV stable to ensure a long life. DrillVent is available in standard transparent colour; transparent complimenting popular external brick and modern rendered finishes.

DrillVent has been tested according to the principles of CEN standard 
EN13141-1: Ventilation for buildings – Performance testing of components/products for residential ventilation.


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 min 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.

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.
