Smoke vent rooflights (AOVs) for Guildford: the essentials
Thinking about smoke vent rooflights (AOVs) in Guildford? The short answer: automatic smoke ventilators at the head of stairwells and atria. The longer answer depends on your roof, which is why we survey before we price.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
Guildford is around 9 km from Woking, and we survey and fit throughout that part of Surrey, including the GU1 district.
