Frameless structural rooflights for Horsham: the essentials
Our frameless structural rooflights service in Horsham 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Typical uses for frameless structural rooflights include architect-led extensions and long slots of light over islands or along party walls.
Neighbouring towns include Crawley (12 km) and Horley (17 km). We offer a survey date when we reply to your enquiry.
Options we can specify in Horsham
- Low-iron extra-clear glass
- Butt-jointed runs for long openings
- Triple glazing
- Heated glass on some ranges
- Solar-control coatings
- Clean modern detail for architect-led schemes
- Double or triple glazed structural units
Things we check at survey
- Large panes need lifting gear and access planning
- Tolerances are tight — the opening must be built square and to size
Planning and building rules for Horsham
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. 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.
Read the planning permission guide before you commit to a design.

Common 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.
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.
Is the survey in Horsham 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 Horsham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
