Frameless structural rooflights in Ystradgynlais: what is involved?
Our frameless structural rooflights service in Ystradgynlais covers minimal glass rooflights with no visible frame from inside. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. Think of frameless structural rooflights for rooms where you want sky without a visible frame.
We work across Powys, including Ystradgynlais, and in neighbouring towns such as Pontardawe and Neath. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Ystradgynlais
Planning rules in Wales are tighter than in England for rooflights: Class C rights do not apply in conservation areas, National Parks or AONBs, so a rooflight there needs planning permission. 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.
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.

Questions about frameless structural rooflights in Ystradgynlais
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.
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
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.
Is the survey in Ystradgynlais free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Ystradgynlais?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
