Frameless structural rooflights in Horley: what is involved?
Thinking about frameless structural rooflights in Horley? The short answer: minimal glass rooflights with no visible frame from inside. The longer answer depends on your roof, which is why we survey before we price.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. In Horley, as anywhere, frameless structural rooflights are the usual choice for rooms where you want sky without a visible frame.
We work across Surrey, including Horley, and in neighbouring towns such as Crawley and Redhill. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Shadow-gap or plastered reveal
- Butt-jointed runs for long openings
- Low-iron extra-clear glass
- Solar-control coatings
- Heated glass on some ranges
- Solar-control and low-iron glass options
- Clean modern detail for architect-led schemes
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
Planning and building rules for Horley
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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about frameless structural rooflights in Horley
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.
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.
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
