Roofing Superstore

The Manthorpe G900 5" Core Drill Vent is designed for gas appliance ventilation and general wall ventilation. It fits easily in new builds or refurbishments using a 5"/127mm core drill. The kit includes a cowl vent for the exterior, a louvre grille for the interior, a 350mm pipe duct, and an optional anti-draught baffle. The baffle reduces both airflow and draught perception. The external cowl minimizes uncomfortable draughts, noise, and light while blocking wind-driven rain, providing 100cm2 of free area, available in brown and terracotta. The internal white louvre also reduces draughts, noise, and light, offering 100cm2 of free area. It provides 10,000mm2 of airflow without the baffle, and 7,000mm2 with the baffle..
