How we approach frameless structural rooflights in Pwllheli
We handle frameless structural rooflights across Gwynedd, including Pwllheli. 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. Typical uses for frameless structural rooflights include rooms where you want sky without a visible frame.
Pwllheli is around 42 km from Bangor, Gwynedd, and we survey and fit throughout that part of Gwynedd, including the LL53 district.
What you can choose
- Triple glazing
- Butt-jointed runs for long openings
- Heated glass on some ranges
- Shadow-gap or plastered reveal
- Solar-control coatings
- Clean modern detail for architect-led schemes
- Long, slim or very large formats
What to check first
- The internal finish (plaster, shadow gap) is agreed before order
- Tolerances are tight — the opening must be built square and to size
Do you need permission in Pwllheli?
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Frameless structural rooflights in Pwllheli: questions
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 a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
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.
How do I book a survey in Pwllheli?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Pwllheli?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
