Manthorpe Felt Lap Ventilator White

The Manthorpe Felt Lap Vent is an excellent refurbishment solution that effectively enhances ventilation in existing roof spaces. Its purpose is to address condensation build-up issues in any roof space featuring a lapped felt or membrane construction. This versatile product is particularly suitable for properties that have recently undergone additional loft insulation installation. The Felt Lap Vent offers a host of features, including a generous airflow capacity of 3,000mm² per G630. It can be easily fitted at joist centres ranging from 400mm to 600mm, and its tapered lead-in facilitates seamless insertion between the felt laps. The Manthorpe Felt Lap Vent is also equipped with three felt clips to ensure secure placement, even if the edge of the felt is degraded.
