Designed for optimal performance and functionality, the airduct FIREBRICK sets a new standard. With 400mm long transitions (204x60mm, 220x90mm) catering to both single and double airbricks, it excels in versatility. The option of an additional bezel, along with site-measured transitions upon request, enhances its adaptability. Engineered from A1-rated steel, the FIREBRICK is meticulously designed to ensure compliance with mechanical ventilation systems in dwellings exceeding 18m (11m in Scotland). Brookvent’s custom bezel seamlessly complements non-brick facades, maintaining the product’s free area without compromise.
