Earlier this year, on the 15th of June, Building Regulations were updated. One of the biggest changes saw an update to Approved Document part F, which covers everything to do with ventilation in residential homes. Changes to part F state that all replacement windows must be installed with trickle vents if the customer is changing more than one-third of their windows. Under these revised regulations, all replacement windows will have to have trickle vents fitted for them to be compliant with both FENSA and Government Building Regulations.
One question we are receiving a lot as a result of this update is whether trickle vents can cause heat loss in the home. The short answer is no*, but allow us to explain why you don’t need to be concerned about heat loss through trickle vents.
How do trickle vents work and what are the benefits?
Trickle vents are an element within a window, situated at the upper part of the frame. They are designed to provide permanent ventilation in a room, even when the windows are closed. Trickle vents allow a small amount of air through the window at all times, and can be opened or closed manually, however, it is recommended that trickle vents remain open at all times to keep fresh, clean air flowing through the home.
Trickle vents are so effective because they work constantly in the background without making the home uncomfortably cold. *Any reduction in the temperature of your home from a trickle vent is very marginal and unnoticeable. If you are concerned about your home feeling cold, it is likely something else and not your trickle vents causing the issue. Take a look at our 5 simple steps to make sure your home is winter ready.
Pros and cons of having trickle vents
| Windows with trickle vents | Windows without trickle vents |
| Cleaner air for your home – trickle vents act as background ventilation, keeping the air in your home fresh and circulated. | No background ventilation can take place, meaning the air in your home will contain more internal pollutants such as germs and bacteria. |
| Less mould and condensation – having trickle vents keeps the air in your home fresh and prevents mould and condensation build-up which can be damaging to not only your décor but your health. | No trickle vents mean you are more likely to suffer from mould and/or condensation issues. |
| Better security – having trickle vents means you can enjoy fresh air without leaving windows open which can pose a security threat.
|
The only way to get any fresh air into your home is through opening windows, which makes easy access for potential intruders, especially at night or if you are not home. |
| Noise reduction – having trickle vents means you can enjoy fresh air with the windows shut, meaning less noise enters your home. | If you live in a particularly noisy area, you might not want your windows open as the noise is disruptive, but this means you compromise on fresh air. |
