Trickle vents allow you to control ventilation and air circulation, helping to reduce condensation and mould. They provide you with a small amount of fresh air into the building without letting a lot of heat escape.
15th June 2022 Part F (ventilation) Changes
If there are already vents fitted on the original windows, then you can fit the same sized vents on the new windows. For example, 2500mm2 EA vents can be replaced with 2500mm2 EA vents or higher. Just remember that the airflow cannot be decreased.
If the existing windows do not have vents, then the replacement windows must have vents fitted to meet the requirements of the revised Approved Document F. For houses in England, that means a minimum airflow of 8000mm2 EA in habitable rooms and 4000mm2 EA in non-habitable rooms.
All windows for new build properties and extensions are required to have adequate background ventilation whether this is by trickle vents, purge ventilation or extraction.
The installation pack includes a selection of universal frame and glazing packers, large 120mm self tapping frame screws (no rawl plugs required) and self tapping cill screws. Fixing screws for extension pieces will also be supplied if required.
