Internal metal ventilation grilles are a range of metal louvre grilles, hit and miss vents and return air grilles manufactured in high quality pressed aluminum. (Please note that hit & miss grilles must not be used for ventilation in connection with gas appliances). Available in three types of finish: plain aluminum (A), brass anodised (BA) and polished brass (PB). Louvre grilles are a permanently open vent with no flyscreen or closing method but with visible airflow marking to comply with the requirements of BS5440 Part 2 2000 and BS EN 13141-1 2004 (suitable for gas appliance ventilation). Adjustable (hit & miss) grilles can be open or closed with an integral flyscreen (not suitable for gas appliance ventilation). Attractive products for sustaining airflow and reducing draughts.
