What do frameless structural rooflights in Crawley involve?
For Crawley 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Frameless structural rooflights suit rooms where you want sky without a visible frame.
We cover all of Crawley and the RH11 district, and nearby Horley and Horsham.
What you can choose
- Triple glazing
- Solar-control coatings
- Heated glass on some ranges
- Shadow-gap or plastered reveal
- Low-iron extra-clear glass
- Double or triple glazed structural units
- Clean modern detail for architect-led schemes
What to check first
- Structural glass specification comes from the manufacturer
- The internal finish (plaster, shadow gap) is agreed before order
Planning, building control and Crawley
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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. 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.

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.
How is it lifted onto the roof?
Larger panes go up with a vacuum lifter, a hoist or a crane. We plan access at survey.
Can a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
How do I book a survey in Crawley?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Crawley?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
