This bottom operated slotvent has been designed to meet the requirements of Part F for new build windows, a regulation which was established in 2006. Part F regulations apply to all new build windows and they must abide by the regulations.
Replacement windows should always provide at least the ventilation of the window being replaced, if not more. It is strongly advised that all replacement windows incorporate some kind of ventilation even if the previous window did not.
This vent achieves optimal equivalent area performance with minimal visual instrusion. Available in either clip or screw fit. The clip fit operations helps to reduce installation and production time.
