What do smoke vent rooflights (AOVs) in Stevenage involve?
For Stevenage homes and buildings we offer smoke vent rooflights (AOVs): automatic smoke ventilators at the head of stairwells and atria. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Typical uses for smoke vent rooflights (AOVs) include blocks of flats and commercial buildings with a smoke strategy.
From Stevenage to Hitchin, Letchworth Garden City and Welwyn Garden City, the same survey-first process applies: measure, specify, fix the price, then fit.

Regulations for smoke vent rooflights (AOVs) in Stevenage
Smoke vents are life-safety equipment: in England the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005. We install to the building's fire strategy and the manufacturer's certification.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fragile-roof safety and access are planned before work starts.
