Felt lap vents allow homeowners to tackle condensation in poorly ventilated areas. Specially designed for roof spaces with lapped felt or membrane constructions, lap vents are most often fitted retroactively into existing roof spaces. This is especially common where new loft insulation has been installed, and roof ventilation needs to be improved as a result.

Our range of felt lap vents are lightweight and easy to fit, slotting neatly between the felt laps in your roof. They also come with clips for easy fixing, even if your roofing felt has become degraded or worn away over time. Delivering up to 3000mm2/m of ventilation, our felt lap vents are the ideal solution for homeowners looking to tackle condensation issues.
