Frameless structural rooflights in Crowborough: what is involved?
We handle frameless structural rooflights across East Sussex, including Crowborough. 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Think of frameless structural rooflights for architect-led extensions and long slots of light over islands or along party walls.
Jobs in Crowborough are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Triple glazing
- Butt-jointed runs for long openings
- Low-iron extra-clear glass
- Heated glass on some ranges
- Solar-control coatings
- Clean modern detail for architect-led schemes
- Double or triple glazed structural units
Before you order: points to check
- Structural glass specification comes from the manufacturer
- The internal finish (plaster, shadow gap) is agreed before order
Consents for frameless structural rooflights in Crowborough
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.
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. 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.

Frameless structural rooflights in Crowborough: 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.
Will I need planning permission in Crowborough?
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.
Is the survey in Crowborough free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
