Frameless structural rooflights for Biggleswade: the essentials
We handle frameless structural rooflights across Bedfordshire, including Biggleswade. 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Think of frameless structural rooflights for architect-led extensions and long slots of light over islands or along party walls.
From Biggleswade to Sandy, Letchworth Garden City and St Neots, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Biggleswade
- Low-iron extra-clear glass
- Triple glazing
- Heated glass on some ranges
- Solar-control coatings
- Butt-jointed runs for long openings
- Double or triple glazed structural units

Before you order: points to check
- Structural glass specification comes from the manufacturer
- Tolerances are tight — the opening must be built square and to size
Consents for frameless structural rooflights in Biggleswade
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.
