Each vent measures 1 metre in length and delivers 25mm² continuous airflow, helping to prevent condensation, mould growth, and moisture damage within the roof space. The system installs directly onto the top of the fascia board, allowing the roofing felt to run cleanly over the vent and into the gutter while maintaining a clear ventilation path. Ideal for new builds, extensions, and refurbishment work, these fascia vents can be installed with or without a soffit and are suitable for both pitched and flat roof applications. The slim profile allows savings in fascia depth while remaining discreet once installed. Manufactured from lightweight, durable material, the vents are designed to resist deformation and prevent the entry of birds and large insects. This system fully complies with UK Building Regulations and British Standards, making it suitable for professional trade use. Dimensions per Vent: Length: 1 metre, Width: 38mm, Depth: 20mm, Airflow: 25mm² continuous ventilation. Other vent sizes and pack quantities are available.
