⚡ At a Glance
- • Ventilation Performance: Creates consistent airflow between felt layers to limit moisture build-up and reduce damp on roof timbers.
- • Best for: Homeowners aiming to improve loft airflow, reduce condensation, and protect roof structure without specialist help.
- • Not ideal for: Roofs without overlapping felt where vents cannot be slid into the felt laps, or non-standard membrane systems.
Each vent measures approximately 280mm x 190mm x 30mm and arrives in a pack of 24. Weather-resistant plastic construction and slide-and-clip fitting enable straightforward, long-term ventilation across felt overlaps.
Reduce Loft Condensation – Thanks to Consistent Airflow Between Felt Layers
Felt lap vents create a channel for air to move along the underside of the roof, maintaining circulation between overlapping roofing felt. Constant airflow interrupts the conditions that allow condensation and damp to form.
Improved ventilation lowers the risk of condensation forming on roof timbers, helping to prevent rot and mould. Multiple vents can be spaced to balance airflow across the loft area.
Quick DIY Installation – With Slide-and-Clip Fitting
Each vent slides into the felt overlaps from inside the loft and locks into place using an integrated clip, so no specialist tools are needed. The simple shape allows repeatable placement along rafters and overlaps.
A homeowner can install several vents in minutes, reducing labour and avoiding professional help for basic ventilation upgrades. Ideal for seasonal checks and straightforward loft improvements.
Durable, Weather-Resistant Construction – With High-Quality Plastic
Manufactured from weather-resistant plastic designed to retain strength and shape across a wide temperature range. The material resists moisture exposure typical of loft environments.
Long-lasting construction reduces the need for frequent replacement and keeps ventilation effective over time. Suitable for both older properties and new builds needing reliable airflow.
