What are trickle vents?

Trickle vents provide rooms in a property with ventilation, and are fitted at the top of windows and doors. They are adjustable so that airflow can be controlled, and come in a range of colours and finishes in order to match the frames they are installed in.
Trickle vents also come in a range of sizes. When new windows or doors are being fitted, the room in question will have an equivalent area (EA) measured in millimetre squares to determine the correct size of trickle vent for the room.

The aim of making trickle vents a legal obligation in new windows and doors is to ensure a better internal living environment by improving airflow for maximum possible ventilation. Trickle vents allow odours and moisture to be dispersed externally, whilst also allowing clean air to enter the property, preventing issues such as mould and damp.
