How we approach frameless structural rooflights in Thetford
Our frameless structural rooflights service in Thetford 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.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. In Thetford, as anywhere, frameless structural rooflights are the usual choice for rooms where you want sky without a visible frame.
From Thetford to Bury St Edmunds, Diss and Wymondham, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Triple glazing
- Shadow-gap or plastered reveal
- Solar-control coatings
- Butt-jointed runs for long openings
- Heated glass on some ranges
- Solar-control and low-iron glass options
- Can run along party walls and side returns
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
Consents for frameless structural rooflights in Thetford
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Frameless structural rooflights in Thetford: questions
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.
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
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 do I book a survey in Thetford?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Thetford?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
