Frameless structural rooflights in Twickenham: what is involved?
Frameless structural rooflights in Twickenham means minimal glass rooflights with no visible frame from inside. We cover the TW1 district and the rest of Greater London, with a survey before any price is fixed.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Think of frameless structural rooflights for architect-led extensions and long slots of light over islands or along party walls.
Twickenham is around 16 km from central London, and we survey and fit throughout that part of Greater London, including the TW1 district.

Consents for frameless structural rooflights in Twickenham
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. 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.

Can a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
