How to Install Your Trickle Vents

You can fit these vents quickly and simply. Here’s a basic installation guide for new and replacement vents:

1. Drill or route a 10mm or 13mm hole through your frame, choosing the right size for best coverage.
2. Line up the vent so it is centred over the new opening for even airflow.
3. Use supplied screws to secure both internal and external parts. Screws should be 10mm in from each end (20mm total off the length).

For leak protection, finish your install by sealing around the external vent area with a high-quality silicone. This defends against weather and keeps your vent working perfectly over time.

What’s in the Package?

You’ll receive all parts needed for a complete setup: 1 x Internal Vent, 1 x External Hood, 4 x End Caps, and 4 x Fixing Screws—no extra components required for standard fits.

Background Ventilation for Healthy Living

Our 400mm vents fit homes and workspaces for a variety of uses—windows, doors, and conservatories all benefit from fresh outside air. Good background ventilation can be vital in high-moisture spaces like bathrooms, kitchens, and basements. In these areas, ventilation helps control humidity, reducing mould risk while improving comfort and air quality. Proper air flow removes odours and reduces allergies or respiratory issues. These vents can support healthy living with regular air exchange. After fitting, you may also notice lower heating or cooling costs as a result of better indoor balance.

For optimal results in cross-ventilation, consider installing two Trickle Vents in opposite frames. This increases airflow, ensuring consistent fresh air in any room.

Cleaning and Maintenance for Window Vents

Keep your vent working efficiently with a little regular maintenance:

• Cleaning: Use a damp cloth to wipe the slot vent and gently brush the external hood and flyscreen to clear dust or particles.
• General Care: Wash with warm, soapy water. Avoid anything harsh or abrasive to maintain the vent’s long-lasting finish.

British Standards & Sustainability

Our vents comply with strict British and international standards, including BS EN 13141-1:2019 for airflow rates. This ensures long-term durability and efficient air flow. Recyclable materials feature throughout each vent, supporting sustainability and reducing environmental impact over their long lifespan.

Ordering Guidelines for Trickle Vents

Carefully check vent length and colour before purchasing. Colour may appear differently on-screen than in reality, so double-check your selection to ensure the best match for your décor.
