How we approach frameless structural rooflights in Rhondda
Frameless structural rooflights in Rhondda means minimal glass rooflights with no visible frame from inside. We cover the CF42 district and the rest of Mid Glamorgan, with a survey before any price is fixed.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Frameless structural rooflights suit rooms where you want sky without a visible frame.
We cover all of Rhondda and the CF42 district, and nearby Tonypandy and Aberdare.

Do you need permission in Rhondda?
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. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
Read the planning permission guide before you commit to a design.

Frameless structural rooflights in Rhondda: questions
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
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.
Will I see the edge of the glass?
From inside, the reveal is finished up to the glass so the edge is hidden. From outside you will see the glass and its edge seal.
Can you work alongside my builder in Rhondda?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Rhondda?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
