Roof Ventilation Terminals

Passivent’s range of roof ventilation terminals have patented double-bank louvres which provide Class A 100% certified rain rejection (BS EN 13030:2001) so that your building can be fully ventilated regardless of weather conditions. They are resistant to continuous wind loads at 51 m/s (BRE tested) and their motorised base dampers control the airflow with excellent thermal and airtightness performance when closed. They are available in a range of designs (modern, traditional, bespoke, bespoke monopitch, circular and aluminium) and a range of sizes. They can also be colour-matched to any RAL or BS colour. Installation is made easier by their lightweight construction and integral sub-base. Further specification detail and controls information can be found by clicking on the individual products.
