Frameless structural rooflights in Sandy: what is involved?
We handle frameless structural rooflights across Bedfordshire, including Sandy. 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.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Frameless structural rooflights suit rooms where you want sky without a visible frame.
Sandy is around 29 km from Luton, and we survey and fit throughout that part of Bedfordshire, including the SG19 district.
What you can choose
- Low-iron extra-clear glass
- Heated glass on some ranges
- Triple glazing
- Butt-jointed runs for long openings
- Solar-control coatings
- Nothing but glass visible from inside
- Clean modern detail for architect-led schemes
Things we check at survey
- The internal finish (plaster, shadow gap) is agreed before order
- Large panes need lifting gear and access planning
Do you need permission in Sandy?
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.

Common 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.
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.
Do you fit frameless structural rooflights in Sandy?
Yes. We survey and fit frameless structural rooflights in Sandy and across Bedfordshire. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Sandy?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
