In the UK, we all get used to the idea of leaving the windows closed – especially during the colder months. Sadly, the ‘colder months’ in the UK can include almost every month outside June and July. That’s why window trickle vents, those small vents atop your window frames, are so useful. They can help us keep the air quality in our homes high all year round, without having to pop open the window and invite ourselves to increasingly cold mornings, afternoons and evenings!
What makes window trickle vents so useful? We reached out to Lock & Key York for answers. With years of experience dealing with windows, we wanted their opinion on how trickle vents improve window efficiency without compromising safety. What makes a trickle vent so useful? How can it make your home more comfortable to live in?
Are Trickle Vents Actually Useful?
Look around the internet, and you can find all sorts of commentary about window trickle vents. Some swear by them, while others say they are a placebo, useless. The debate around whether they are useful, though, has been defunct; no argument that well-maintained trickle vents on windows are beneficial. The question then moves to whether they are essential.
Well, according to building regulations that came into effect in 2022, they are now essential. Any household that has new windows installed needs to make sure that the new windows provide the same – or, ideally, better – airflow than the previous windows. If your old windows have trickle vents and your new ones don’t, they probably fail that test!
Any household deemed airtight will benefit from installing window trickle vents. It also helps households with rooms that have limited ventilation, especially bathrooms and drying rooms. They are highly effective, reliable appliances that cost nothing to run and can gradually make your room feel a little fresher, while removing dampness from the air.
Is a trickle vent a useful appliance? Absolutely. Is it essential? Not always, but we would recommend a trickle vent to be fitted on every window in your house. There is no real harm in having them open.
When Trickle Vents Matter Most For UK Households
While not technically essential, window trickle vents are the best way to regulate airflow in a room without opening windows or turning on extractor fans. When are they most useful, though?
Airtight Households
Having an airtight home is, generally, considered a good thing. Airtightness means your home is not allowing air or energy to escape, especially in winter, which results in lower heating bills. Still, airtightness can also lead to another problem you might not consider: dampness and staleness.
Why? Because the air circulating in your home needs to be replaced with cool, fresh air from the outside. Otherwise, that leads to breathing in stale air in many of your rooms. If you ever walk into a cupboard and find that it smells stale, it’s likely due to a lack of airflow. Installing window trickle vents would help you remove that stale air and replace it with fresh air.
We all want airtight homes, as they limit noise pollution and reduce heat loss. You need to counter that airtightness, though, by having something like trickle vents on windows. These small vents provide a simple solution to a complex problem that can often go unnoticed.
High Humidity Rooms
The same goes for rooms with appliances that generate humidity. For example, your bathroom, kitchen, and drying room tend to have high humidity.
Why? Because the appliances create that dampness in the air itself. These appliances often produce steam, and if it is not properly extracted, it lingers. It sticks to the walls, the fixtures and around any exits. That means you might find these rooms becoming damp over time, making them uncomfortable to sit in for prolonged periods.
Over time, though, if the damp and humid air is not removed, it becomes a problem. Dampness forms on your windows and walls, which eventually leads to mold. Mould is a serious problem and can be a major health risk, especially for people with respiratory conditions. If you have window trickle vents, though, they help expel dampness gradually without having to open the windows.
Leave your window trickle vents open 24/7 in these rooms. It will help to slowly remove the damp air and replace it with cool and dry air from outside. Keeping the air fresh helps prevent damp and mould, and it also makes the room’s atmosphere more comfortable.
Poor Natural Ventilation
Some rooms have poor ventilation for various reasons. It could be down to low-quality windows or no windows. It could even be caused by objects or furniture blocking airflow.
Whatever the cause, the problem is the same: you need to improve ventilation ASAP. Many of us rely on tools like extractor fans to do this, or simply open windows. If you forget to turn off that fan, though, you can look forward to a larger energy bill. Forget to close the window, and the room – especially in winter – can feel like walking into a fridge freezer!
With a trickle vent, though, that is easily avoided. You instead keep ventilation consistent but gentle. You should consider installing trickle vents in rooms like interior cupboards, walk-in wardrobes, and any rooms where you feel the air becomes stale or damp without improvement.
Evaluate Your Airflow And Install Trickle Vents ASAP
With no cost to run the window trickle vents, there is no downside to leaving them open. They never allow air to flow in quickly enough to chill a room, nor to waste noticeable amounts of heat.
Instead, they simply replace the overly damp or stale air with fresh air. It’s a simple conversion and one that makes a real difference to the quality of your room. It can even prevent rooms from becoming damp or mouldy, meaning you get more use out of your appliances, fixtures and furniture.
Install trickle vents on windows, and you should find your winters warmer, without the dampness and poor ventilation problems you might have dealt with in previous winters.
