Frameless structural rooflights in New Malden: what is involved?
For New Malden 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.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Frameless structural rooflights suit architect-led extensions and long slots of light over islands or along party walls.
Neighbouring towns include Surbiton (3 km) and Kingston upon Thames (4 km). We offer a survey date when we reply to your enquiry.
What you can choose
- Shadow-gap or plastered reveal
- Solar-control coatings
- Low-iron extra-clear glass
- Butt-jointed runs for long openings
- Triple glazing
- Nothing but glass visible from inside
- Can run along party walls and side returns
Before you order: points to check
- The internal finish (plaster, shadow gap) is agreed before order
- Tolerances are tight — the opening must be built square and to size
Do you need permission in New Malden?
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. 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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

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.
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.

Yes — it is structural glass designed for the job. The support is hidden rather than missing.
