What are Trickle Vents Windows | Trickle Ventilation

Trickle vents Windows are small openings, usually located at the top of windows or doors, that allow a controlled amount of fresh air to enter a room. These vents are crucial for maintaining good air quality and preventing issues like condensation. Whether it’s trickle vents for UPVC windows, patio doors, or even double glazing, these handy features ensure better ventilation without compromising security. 

Trickle vents in windows are especially important in modern houses as homes are designed to be more airtight. A constant trickle feed of air helps to remove excess moisture buildup from the air that can cause mould.

Are Trickle Vents needed a Legal Requirement?

In the UK, trickle vents for windows are often a requirement in new builds or replacement windows under Building Regulations Part F. These regulations ensure that homes are equipped with adequate ventilation to prevent issues like poor air quality and condensation. 

Trickle Vents Windows and Building Regulations 2022

The Building Regulations Approved Document Part F was revised in June 2022 to enhance ventilation standards in homes as buildings become increasingly airtight. 

Background ventilation, such as trickle vents, works alongside other ventilation strategies to ensure adequate air quality in living spaces and to prevent the accumulation of condensation.

When replacing windows that already have background ventilators (trickle vents), the replacement windows must include vents of at least the same size.

For windows without existing trickle vents, it must be demonstrated that the new replacement windows will not reduce ventilation levels. Since modern windows tend to be more airtight than older ones, in most cases, trickle vents will need to be incorporated into the new window frames to maintain adequate airflow.

It's important to note that windows equipped with a lockable ventilation gap, commonly referred to as a night latch, are not considered an adequate form of background ventilation under the updated Building Regulations.

Window frames do look better without a trickle vent, but the benefits of using trickle vents as part of a ventilation system in the whole house cannot be ignored.

Types of Trickle Vents

Frame-Integrated Vents

These are built into the window frame and are discreet in appearance.

Surface-Mounted Vents

Installed on the surface of the window frame, these can be retrofitted to existing windows.

Glazing-Mounted Vents

Positioned directly on the glass pane, these are less common but still effective.

Trickle Vents Installation Process

Installing trickle vents involves the following steps: 

Marking the Location

Typically, vents are placed at the top of the window or door.

Drilling Holes

Precision is crucial to ensure proper airflow and a clean finish.

Securing the Vent Cover

Covers like UPVC door vent covers are screwed into place for durability.

Testing the Ventilation

Ensure the vent allows adequate airflow without letting in drafts.

Trickle Vents for Double Glazing

Double glazing vents are becoming a standard feature in modern homes. They ensure your windows retain their energy efficiency while allowing fresh air circulation. If you’re considering replacing old vents or installing new ones, opt for high-quality, energy-efficient options. 

Trickle Vents for UPVC windows

If installing trickle vents to uPVC window frames, be aware that there may be a metal reinforcement section inside the window frame cavities, which will make it harder to get through. Timber is the easiest material to install trickle vents to, but aluminium windows are very difficult and may not be possible. 

Renowned suppliers like Daylight Glazing provide high-quality trickle ventilators for windows, UPVC door vent covers, and more. We also offer professional installation services to ensure optimal functionality.
