What do smoke vent rooflights (AOVs) in Cheshunt involve?
Smoke vent rooflights (AOVs) in Cheshunt means automatic smoke ventilators at the head of stairwells and atria. We cover the EN8 district and the rest of Hertfordshire, with a survey before any price is fixed.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Typical uses for smoke vent rooflights (AOVs) include communal stairwells, corridors and atria.
Neighbouring towns include Waltham Abbey (2 km) and Enfield (7 km). We offer a survey date when we reply to your enquiry.

Rules and responsibilities in Cheshunt
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.
Read the planning permission guide before you commit to a design.
