What do smoke vent rooflights (AOVs) in Walkden involve?
Smoke vent rooflights (AOVs) in Walkden means automatic smoke ventilators at the head of stairwells and atria. We cover the M28 district and the rest of Greater Manchester, with a survey before any price is fixed.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Think of smoke vent rooflights (AOVs) for communal stairwells, corridors and atria.
From Walkden to Farnworth, Swinton and Tyldesley, the same survey-first process applies: measure, specify, fix the price, then fit.

What to check first

- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
Building control and safety duties in Walkden
Smoke vents are life-safety equipment: in England the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005. We supply manufacturer-certified units and arrange installation, commissioning and servicing through specialist smoke-control engineers.
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.
