Why Window Installers Choose White Trickle Vents: A Guide to EasyVent Options
What Are White Trickle Vents and Why Do They Matter?
White trickle vents are a go-to solution for installers looking to maintain airflow in modern buildings without compromising on aesthetics. Installed at the head of PVCu window frames, these discreet vents allow for continuous, background ventilation that helps reduce condensation and maintain indoor air quality — even when windows are shut.
When fitted correctly, they:
- Reduce the build-up of moisture and damp
- Improve thermal efficiency without full window ventilation
- Meet Part F Building Regs for background ventilation
- Blend with white PVCu frames for a professional finish
If you’re installing windows in residential new builds, commercial upgrades, or replacing failed vents, white trickle vents are often the preferred option due to their universal fit and clean appearance.
Why Installers Rate EasyVent by GSD
The EasyVent range has been trusted by leading fabricators, including Dekko Window Systems. Their sales director called it “extremely simple to fit and operate, and made from the highest UV-resistant material” — a real vote of confidence for trade professionals.
Three key features that make the EasyVent trickle vents stand out:
- Made from ASA UV-Stable Plastic – Withstands weathering over time
- Snap-On Cap Covers Screws – For a clean, tamper-proof look
- Multi-Position Operation – Give users control over airflow

Which Size Do You Need? 200mm vs 300mm vs 400mm
Choosing the right size trickle vent depends on your frame width and the level of background ventilation required. All sizes in our EasyVent range meet BS EN 1026:2000 and BS EN 1027:2000 testing standards, but each offers different airflow volumes and installation footprints.
Common Use Cases by Size:
- 200mm White EasyVent – Ideal for narrow sash windows or smaller rooms like bathrooms and utility areas.
- 300mm White EasyVent – The most common mid-size option for domestic installations.
- 400mm White EasyVent – Preferred for large window openings, open-plan rooms, or where maximum airflow is needed.
