How do trickle vents work?
Trickle vents are ventilators that are integrated into the frames of windows and doors to allow a small, constant airflow from outdoors to the interior of a building. Trickle vents are staggered on the inside and outside of the window or door frame and feature a cover that can be opened or closed to either allow or restrict airflow.
Should I close trickle vents during the winter?
No, you should keep your trickle vents open during the winter as their primary job is to prevent the build-up of mould and condensation. They do this by allowing a controlled amount of air to escape the window or door frame, so it’s recommended that they stay open during the winter.
What are the main benefits of a window trickle vent?
There are several benefits to using trickle vents in your window and door frames. They are:
- Reduced condensation - Trickle vents reduce condensation build-up within the window or door frame. This also helps to reduce any sort of mould from growing around the frame, which can be a common issue in buildings with poor ventilation.
- Controlled ventilation - With controlled ventilation, a trickle vent helps to regulate the temperature and humidity level of the rooms they’re installed in.
- Better air quality - Allowing fresh air to circulate throughout a room helps to improve the air quality.
- Improved energy efficiency - Trickle vents help with the energy efficiency of a building thanks to their ability to regulate the temperature of the room they’re installed in.
- Improved window lifespan - The lifespan of a window or door frame is enhanced with the use of trickle vents because they allow the frame to ‘breathe’. Regular ventilation not only helps reduce condensation and mould but also prevents a build-up of pressure. This helps to decrease the chance of cracks forming.
Do you need trickle vents on every window?
Before June 2022, trickle vents only needed to be fitted if existing windows or doors being replaced already had them, or if a new home or extension was being built.
However, new regulations ensure that all new homes have adequate ventilation, and all windows and doors must comply with these rules whether trickle vents are installed or not.
