What do frameless structural rooflights in Feltham involve?
Thinking about frameless structural rooflights in Feltham? The short answer: minimal glass rooflights with no visible frame from inside. The longer answer depends on your roof, which is why we survey before we price.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. In Feltham, as anywhere, frameless structural rooflights are the usual choice for architect-led extensions and long slots of light over islands or along party walls.
Neighbouring towns include Ashford, Surrey (3 km) and Hounslow (4 km). We offer a survey date when we reply to your enquiry.
What you can choose
- Low-iron extra-clear glass
- Butt-jointed runs for long openings
- Heated glass on some ranges
- Solar-control coatings
- Shadow-gap or plastered reveal
- Clean modern detail for architect-led schemes
- Double or triple glazed structural units
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 Feltham?
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Frameless structural rooflights in Feltham: questions
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.
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.
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.
Is the survey in Feltham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Feltham?
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.
