What do frameless structural rooflights in Eastbourne involve?
Frameless structural rooflights in Eastbourne means minimal glass rooflights with no visible frame from inside. We cover the BN21 district and the rest of East Sussex, with a survey before any price is fixed.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Typical uses for frameless structural rooflights include architect-led extensions and long slots of light over islands or along party walls.
Neighbouring towns include Hailsham (11 km) and Seaford (13 km). We offer a survey date when we reply to your enquiry.

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

Common 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.
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.
Do I need to be at home for the survey in Eastbourne?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Eastbourne free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
