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.

Passivent’s Airscoop, Airstract, Airstract iAT, Hybrid Plus Airstract and Litevent Airstract roof terminals are now also available for modelling within the IES Virtual Environment providing a fast, streamlined and easy-to-use method of simulating the effects of these terminals within VE models. A dedicated VE navigator has been created to guide users through a stepped process from importing the goods into your model, configuring your operation, preparing and applying to rooms, thermal simulation and compliance analysis.
