450mm Double Vented Soffit 9mm Board x 5m (25mm Air Gap) – White
This 450mm x 5m Concord 9mm Vented Soffit Board in White is a high-performance uPVC profile designed for both new build and refurbishment projects. It features integral ventilation slots that provide a 25,000mm² per metre continuous air gap. This ensures the roof void is effectively ventilated to prevent moisture build-up and timber decay, meeting the requirements of Building Regulations for roofspace ventilation. As a BBA Approved white profile, it offers a long-term, low-maintenance solution for protecting the roofline.
Manufactured by Swish Building Products to ISO 9001:2015 standards, the board is constructed with a high-density cellular PVC-U core beneath an impact-modified outer skin. The ventilation slots are precision-designed to allow airflow while preventing the ingress of large insects. Lightweight and easy to work with using standard woodworking tools, this board provides a clean, professional finish that requires no annual painting or maintenance.
