What do frameless structural rooflights in Camborne involve?
Our frameless structural rooflights service in Camborne 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.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. Typical uses for frameless structural rooflights include architect-led extensions and long slots of light over islands or along party walls.
Camborne is around 18 km from Truro, and we survey and fit throughout that part of Cornwall, including the TR14 district.

Things we check at survey

Planning and building rules for Camborne
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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.
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.
Read the planning permission guide before you commit to a design.

Frameless structural rooflights in Camborne: questions
Can a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
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.
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
Can you work alongside my builder in Camborne?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Camborne?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
