Trickle Vents Explained
A trickle vent is the raised horizontal plastic bar positioned above the window. The vents can be opened by pulling the bar towards you and you should be able to feel the air-flow through the vent with your fingers. Trickle vents are an alternative means of ventilating a room rather than opening a window and can be useful in the winter months when it is too cold to open a window.
However trickle vents in the window frame provide only background ventilation and are not usually enough on their own but they will help to reduce the need to ventilate the room by opening the windows.
A lack of ventilation can cause condensation anywhere in the home especially in kitchens and bathrooms.
Building Regulations also require that if your home already has trickle vents fitted then you will have to have trickle vents fitted to your replacement windows.
However, if your property doesn’t have trickle vents fitted then you will not have to go to the expense of having trickle vents fitted to your replacement windows unless, of course, you want to.
Trickle vents retail at around about £15 each as at January 2008 prices.
