How we approach frameless structural rooflights in Barry
Thinking about frameless structural rooflights in Barry? The short answer: minimal glass rooflights with no visible frame from inside. The longer answer depends on your roof, which is why we survey before we price.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. Frameless structural rooflights suit architect-led extensions and long slots of light over islands or along party walls.
Jobs in Barry are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Planning, building control and Barry
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
