Window Vents
Window vents provide permanent background ventilation for uPVC, timber and aluminium windows, allowing fresh air to circulate while helping to reduce condensation and improve indoor air quality. Whether you're replacing an existing vent, upgrading an older installation or specifying ventilation for a refurbishment project, our range includes genuine products suitable for almost every style of double glazed window.
At HandleStore you'll find replacement trickle vents, premium aluminium window vents, recessed timber systems, external trickle vent covers and specialist accessories from leading manufacturers including Titon, Brookvent and Greenwood. If you're unsure which product you need, our Replacement Trickle Vent Size Guide explains how to identify your existing vent before ordering.
Why Window Vents Matter
Window vents provide continuous background ventilation without needing to leave the window open. They help improve air circulation throughout the home, reduce the build-up of condensation and contribute towards a healthier indoor environment. Modern trickle vents also allow controlled airflow while maintaining security and weather resistance when the window is closed.
Many replacement window vents are now available with higher Equivalent Area (EA) ratings to help meet current Building Regulations, making it easier to upgrade older installations where improved background ventilation is required.
Types of Window Vent
Different windows require different ventilation solutions. Our collection includes controllable replacement trickle vents, premium aluminium window vents, recessed timber vents, pull-cord operated vents for high-level windows, external trickle vent covers and specialist accessories. Many products are available as complete vent sets or as individual internal and external components, allowing you to replace only the parts you need.
Choosing the Right Window Vent
When selecting a replacement, check the slot size, fixing centres and overall length of your existing vent. If Building Regulations require a specific Equivalent Area (EA), matching the replacement vent with its corresponding external cover helps maintain the manufacturer's tested ventilation performance. Our product pages include detailed dimensions, airflow ratings and fitting information to make selecting the correct replacement straightforward.
