Frameless structural rooflights in Islington: what is involved?
For Islington 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.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Think of frameless structural rooflights for rooms where you want sky without a visible frame.
Islington is around 3 km from central London, and we survey and fit throughout that part of Greater London, including the N1 district.
Options we can specify in Islington
- Low-iron extra-clear glass
- Butt-jointed runs for long openings
- Triple glazing
- Heated glass on some ranges
- Shadow-gap or plastered reveal
- Solar-control and low-iron glass options
- Long, slim or very large formats
Things we check at survey
- Structural glass specification comes from the manufacturer
- Tolerances are tight — the opening must be built square and to size
Planning, building control and Islington
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

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 a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
Is the survey in Islington free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Islington?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
