Easy to fit and install with a tapered lead-in that aids in smoothly slotting between the felt laps, these Felt Lap Vents from Manthorpe are refurbishment products that increase ventilation in your existing roof spaces.
With three felt clips that secure the vents in place, regardless of whether felt edges are jagged or deteriorated, these vents are often fitted retrospectively to buildings where extra loft insulation has recently been installed. However, they can also reduce condensation build-up in any roof space featuring a lapped felt/membrane structure.
Your vents won't fulfil the requirement for roof ventilation solely on their own, as you can expect them to only offer airflow through the felt laps. You likely will need to take other measures for sufficient ventilation.
