Installation

It is advised to use this product in conjunction with a Timloc Airbrick, this enables further features such as preventing vermin and small critters from entering.

  1. The installation location for this product should be with the airbrick and upper front opening positioned above the finished external ground level. (Typically same level as ground level DPC)
  2. The lower rear opening of this product should be positioned into the void underneath the ground floor without anything obstructing it.
  3. A vertical extension enables it to be stretched, making it suitable between 5-7 brick courses.
  4. Building Regulations require an unrestricted airflow inside the void of at least 1500mm² per metre run of wall. To achieve this, space your ventilators at 4m centres; however, if stagnant pockets of air may be present, Timloc suggests a spacing of 2m.
  5. NBHC recommends that ventilators are spaced at a maximum of 2m, with positions no more than 450mm from the ends of the wall.
  6. Ensure you have ventilators at opposite sides of the building; this will enable a cross airflow. Ideally, you should have one for either side of the building.
  7. You must create openings for any diving walls in the void below to enable unrestricted airflow.
  8. This product will fit cavities with an external leaf of 100-102.5mm, a minimum cavity width of 50mm and across a cavity of 100mm. You can get extension sleeves to accommodate thicker walls or broader cavities.
  9. To be installed with a DPC Cavity tray and wall weeps to collect any water ingress.
