Trickle vent – A trickle vent in your door or window will give provide ventilation to the property. Air circulation is important in order to reduce moisture in the air and helps reduce condensation and mould.
On an opening window, the vent will be placed into the opening window sash, however if the window is fixed, it will be fitted into a deep outer frame at the top. If used ensure there is suitable clearance for the vent control.
Please note: If you’re installing into a new build it’s now compulsory by law to have trickle vents fitted to all doors and windows.
