How we approach frameless structural rooflights in Cwmbran
We handle frameless structural rooflights across Gwent, including Cwmbran. In short: minimal glass rooflights with no visible frame from inside. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. In Cwmbran, as anywhere, frameless structural rooflights are the usual choice for architect-led extensions and long slots of light over islands or along party walls.
Cwmbran is around 8 km from Newport, Gwent, and we survey and fit throughout that part of Gwent, including the NP44 district.
What you can choose
- Low-iron extra-clear glass
- Solar-control coatings
- Heated glass on some ranges
- Triple glazing
- Shadow-gap or plastered reveal
- Double or triple glazed structural units
- Long, slim or very large formats
What to check first
- Large panes need lifting gear and access planning
- The internal finish (plaster, shadow gap) is agreed before order
Planning and building rules for Cwmbran
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
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.

Frameless structural rooflights in Cwmbran: questions
How is it lifted onto the roof?
Larger panes go up with a vacuum lifter, a hoist or a crane. We plan access at survey.
Is frameless glass as strong as a framed rooflight?
Yes — it is structural glass designed for the job. The support is hidden rather than missing.
Can it open?
Some frameless designs include a sliding or hinged opening element, but most are fixed. Pair with an opening unit if you need ventilation.
Can you work alongside my builder in Cwmbran?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Cwmbran?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
