Made from durable black PVC, this Hambleside Danelaw Black Roofing Felt Lap Vent features a shallow and tapered design and offers 2,280mm² airflow per vent. It is suitable for professional and DIY installation, retrofitted from the inside of cold pitched roofs and lofts to limit condensation where it proves an issue.
This vent is easy to fit, slotting between the overlaps in the roofing underlay beneath tiles or slates. It establishes ventilation openings where roof spaces lack proper provision for ventilation or where existing ventilation air paths are blocked, particularly when loft insulation is upgraded. The shallow and tapered design is compatible with frequently encountered rafter spacings and ensures easier fitting between the roofing felt or underlay where overlaps are tight.
