Frameless structural rooflights for March: the essentials
For March 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 homes in the East have low-pitched roofs on later extensions, which are better served by flat rooflights than pitched roof windows. Think of frameless structural rooflights for architect-led extensions and long slots of light over islands or along party walls.
Neighbouring towns include Wisbech (14 km) and Ely (21 km). We offer a survey date when we reply to your enquiry.
What you can choose
- Low-iron extra-clear glass
- Triple glazing
- Solar-control coatings
- Shadow-gap or plastered reveal
- Heated glass on some ranges
- Can run along party walls and side returns
- Long, slim or very large formats
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
Planning and building rules for March
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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. 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.

Frameless structural rooflights in March: questions
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
Can it open?
Some frameless designs include a sliding or hinged opening element, but most are fixed. Pair with an opening unit if you need ventilation.
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.
