What are trickle vents?

There’s a lot of jargon surrounding the components of modern windows and doors. Although Unicorn Windows avoid using these confusing terms, we like to keep our customers informed of the technical stuff. Trickle vents is one such phrase that leaves many of our customers and other browsers searching for advice on window upgrades a little perplexed. Here, we take a closer look at what trickle vents are and whether your home needs them.

About trickle vents

Usually found at the very top of a window or door, trickle vents provide a slim opening that allows air to flow into the property. There are several trickle vent options to explore. Trickle vents can be installed courtesy of a through frame or over frame design, or alternatively glazed in. Trickle vents are suitable for use across a number of framing materials, including PVC-U, timber, steel and aluminium.

Many window designs don’t incorporate trickle vents, which has led to numerous people questioning whether or not they have a part to play in the world of modern windows and doors.

Modern windows are airtight, which is excellent news for the energy efficiency status and draught-proofing capabilities of your property. However, it’s not such good news for moisture and air quality levels. Condensation is an issue on the windows in many homes, as AXA Insurance notes:

“It doesn’t matter whether you live in a listed building or a newly built apartment – condensation can have a big impact. It might have small beginnings, but if you don’t deal with condensation right away it can develop into greater and longer-lasting problems. These include damp and mould, which can damage your walls and furniture, and become health hazards to both you and your family.”

There are many steps you can take to reduce and even remedy window condensation issues, but could trickle vents be the answer?

The importance of trickle vents

Poor home ventilation results in a number of unhealthy and uncomfortable consequences for the people within. The poor ventilation and the resulting condensation will affect the fabric of your property. It can also impact your health, particularly if issues remain untreated. Letting fresh air in and stale air out is a vital part of regulating moisture and humidity. We understand that it’s not possible to have your windows and doors open around the clock to ensure good ventilation, particularly when the weather gets cooler or you’re away from home. Trickle vents provide ventilation without compromising home security.

Do I need trickle ventilation?

According to the latest building regulations, trickle ventilation should be incorporated into the window framework. This applies to all habitable rooms that are 5,000mm² in size as well as kitchens, bathrooms and utility areas that are 2,500mm² in size. Trickle vents are not mandatory, but some form of ventilation via the approved alternative methods is normally required.

Trickle vents do provide a number of advantages when compared to alternative ventilation systems. As well as supplying permanent ventilation and security, trickle vents ensure the constant and consistent flow of fresh air throughout the home.
