About this item
- Included: Pack of 24 felt lap vents designed specifically to improve loft and attic ventilation. These vents increase airflow through the roof felt laps, helping prevent loft condensation, damp patches, trapped moisture and winter build-up. Ideal for improving overall roof airflow efficiency.
- Dry Loft: Increase airflow in your loft or attic and prevent damp, moisture and condensation using high-performing loft vents and roof felt vent technology. These vents help release steam rising from bathrooms, showers and kitchens, reducing the risk of mould and keeping your loft space dry throughout the winter.
- Install: Simple clip-in installation — each vent fits directly between the roof felt joins to instantly improve airflow loft ventilation and reduce condensation build-up. No tools required. Once fitted, the vents create continuous airflow channels that support long-term loft and attic moisture control.
- Size: Each lap vent measures 280mm x 190mm x 30mm, providing wide, effective coverage for boosting airflow throughout the loft space. The generous size ensures improved ventilation across multiple felt laps, helping reduce trapped moisture and supporting better overall attic ventilation performance.
- Universal Fit: Designed with a universal fit, these vents slot between joists from 350mm to 600mm, making them ideal for nearly all UK loft setups. Acts as a reliable air vent for loft condensation, improving airflow across the entire roof area and preventing long-term issues caused by moisture and poor ventilation.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
