Smoke vent rooflights (AOVs) for Frome: the essentials
Our smoke vent rooflights (AOVs) service in Frome covers automatic smoke ventilators at the head of stairwells and atria. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Think of smoke vent rooflights (AOVs) for blocks of flats and commercial buildings with a smoke strategy.
Frome sits about 10 km from Warminster and 13 km from Trowbridge, and we cover the whole BA11 postcode district and the roads in between.

Rules and responsibilities in Frome
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. Fire classification of rooflight materials near boundaries is checked at specification.

Common questions
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.
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
Do you fit smoke vent rooflights (AOVs) in Frome?
Yes. We survey and fit smoke vent rooflights (AOVs) in Frome and across Somerset. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Frome?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
