140° Roof Smoke Vent with Daily ventilation
Surespan SRHP/AOV and SRHE/AOV Smoke Vents can be made to any size up to 1800 x 3000mm. They are fully compliant with EN12101-2 and CE Marked. The thermally broken AOV is insulated with a U-value of 0.43 W/m²K. On sizes smaller than 1300 x 1300 (SRHP/AOV), Non-combustible Mineral Wool insulation can be specified. Surespan smoke vents can also be used as roof access and daily ventilation.
The thermally broken lid incorporates an unbroken bubble and blade seal. The standard height of upstand is 300mm. The remaining parts of the upstand are filled with 50mm thick CFC and HCFC free Polyisocyanurate insulation. This offers a high level of thermal insulation against heat loss and condensation, together with excellent sound absorption properties. A T4 Adapt or kerb can be fitted to allow installation onto an existing weathered builders kerb (by others).
Aluminium Curb liner fitted as standard.
All of our smoke ventilators are manufactured to meet the requirements of Building Regulations, Approved Document B, BS9999 and EN12101-2 and are supplied CE marked.
