What do frameless structural rooflights in Purley involve?
Thinking about frameless structural rooflights in Purley? 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.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Typical uses for frameless structural rooflights include architect-led extensions and long slots of light over islands or along party walls.
Neighbouring towns include Coulsdon (3 km) and South Croydon (3 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Purley
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.
Read the planning permission guide before you commit to a design.

Frameless structural rooflights in Purley: 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.
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 Purley free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Purley?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
