The best ventilation for windows in Bromley, Dartford and Maidstone

In today’s environment, it’s crucial to minimise the presence of bacteria in your home. Allowing a gentle flow of natural, fresh air from one side of the window to the other can be immensely beneficial as it helps to decrease moisture in the air and prevents the accumulation of mould in your property.

Trickle vents serve as a valuable solution for improving indoor air quality. They enable you to ventilate a room without the need to keep your window wide open, enhancing security. They also contribute to energy efficiency, enabling you to maintain a comfortable temperature in your room throughout the entire year.

    Vital ventilation for your home

    Trickle vents are fitted to the top horizontal window frame and can help create ventilation and reduce condensation. The small opening allows vital ventilation in, allowing healthy air to circulate into the room and polluted air to be eliminated from entering, helping to reduce the threat of condensation by allowing humid air to escape.

    Why our concealed overhead ventilation won’t ruin you’re the look of your windows

    The last thing you will want is for a trickle vent to ruin the aesthetics of your new windows. We recognise having so many external vent canopies can have a negative impact on the appearance of your new windows and, in turn, your property. So, we have worked with our suppliers to offer a concealed overhead vent system. Our system incorporates the external trickle vent in the head of the outer frame, so it is concealed to provide a much-improved finish. It is available on most of our uPVC products and allows us to comply with all the current legislation without having a negative impact on the appearance of your new windows.

    Trickle vent regulations for replacement windows

    In 2022 new regulation guidelines came into force for existing homes that stated every replacement window, regardless of whether the windows being replaced had vents in them, should be fitted with trickle vents if no background ventilation alternative is being installed. If you are replacing or upgrading the windows in your home, don’t worry, because we can explain all you need to know – and have the perfect solution.

    What do the recent trickle vent regulations mean?

    New Building control Rules required 8000mm2 vents to be fitted into almost all habitable rooms. To comply, most two-three segment windows are required to have 3x2500mm2 vents fitted in the sashes/head of the window. The aim is to ensure every home receives adequate ventilation through trickle vents that have to be positioned in the upper frame of a window.

    Future proof your windows, and home, with trickle vents

    Updating your windows is a sure way to add value to your property. If you fail to ensure trickle vents are incorporated into your new windows, however, it could affect the sale of your home. You will need to obtain a completion certificate to prove the windows followed the regulations.
