If you're researching replacement windows, you'll come across trickle vents quickly, changes to building regulations have thrown them into the spotlight. But what are they, and what do they mean for your project?
Trickle vents are small devices fitted to the window frame, or between the glass and frame, designed to be opened and closed by the homeowner. Open, they allow a gentle trickle of fresh air to circulate, with the window itself staying closed and locked.
Why do they matter? Modern homes are sealed far more tightly than older ones, which is excellent for energy bills but can trap moisture and stale air. Trickle vents provide controlled background ventilation: fresher air, less condensation and a healthier home, without heat pouring out of an open window or any compromise on security.
Building regulations now require background ventilation in most replacement window installations, so in many cases, your new windows will need them. The rules have nuances, and a good installer will tell you exactly what applies to your project rather than leaving you to decode the regulations yourself.
