What do frameless structural rooflights in Bodmin involve?
For Bodmin homes and buildings we offer frameless structural rooflights: minimal glass rooflights with no visible frame from inside. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Frameless structural rooflights suit architect-led extensions and long slots of light over islands or along party walls.
Bodmin is around 33 km from Truro, and we survey and fit throughout that part of Cornwall, including the PL31 district.
What you can choose
- Low-iron extra-clear glass
- Triple glazing
- Shadow-gap or plastered reveal
- Heated glass on some ranges
- Butt-jointed runs for long openings
- Double or triple glazed structural units
- Nothing but glass visible from inside
Things we check at survey
- Tolerances are tight — the opening must be built square and to size
- Structural glass specification comes from the manufacturer
Do you need permission in Bodmin?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
Read the planning permission guide before you commit to a design.

Questions about frameless structural rooflights in Bodmin
Can a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
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.
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 Bodmin?
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 Bodmin?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
