What do frameless structural rooflights in Llantwit Major involve?
Our frameless structural rooflights service in Llantwit Major 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.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Typical uses for frameless structural rooflights include architect-led extensions and long slots of light over islands or along party walls.
From Llantwit Major to Cowbridge, Bridgend and Barry, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Heated glass on some ranges
- Low-iron extra-clear glass
- Triple glazing
- Solar-control coatings
- Shadow-gap or plastered reveal
- Solar-control and low-iron glass options
- Long, slim or very large formats
What to check first
- Tolerances are tight — the opening must be built square and to size
- Large panes need lifting gear and access planning
Consents for frameless structural rooflights in Llantwit Major
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.
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. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.
Read the planning permission guide before you commit to a design.

Questions about frameless structural rooflights in Llantwit Major
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 a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
Do I need to be at home for the survey in Llantwit Major?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Llantwit Major?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
