Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go.

Planning and building rules in England
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.

Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
Who is responsible for maintaining smoke vents?
The responsible person (or duty holder in Scotland, appropriate person in Northern Ireland) for the building must keep fire safety systems maintained. We can arrange servicing and keep records.
Do you design the smoke strategy?
No — the strategy comes from the building's fire engineer or designer. We supply, install, commission and service to it.
