How we approach frameless structural rooflights in St Ives
For St Ives 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.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. Typical uses for frameless structural rooflights include architect-led extensions and long slots of light over islands or along party walls.
St Ives sits about 8 km from Huntingdon and 18 km from St Neots, and we cover the whole PE27 postcode district and the roads in between.
What you can choose
- Low-iron extra-clear glass
- Shadow-gap or plastered reveal
- Butt-jointed runs for long openings
- Triple glazing
- Solar-control coatings
- Double or triple glazed structural units
- Solar-control and low-iron glass options
What to check first
- The internal finish (plaster, shadow gap) is agreed before order
- Structural glass specification comes from the manufacturer
Consents for frameless structural rooflights in St Ives
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.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Frameless structural rooflights in St Ives: questions
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.
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.
Can a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
