What do frameless structural rooflights in Frome involve?
Thinking about frameless structural rooflights in Frome? 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.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. Typical uses for frameless structural rooflights include architect-led extensions and long slots of light over islands or along party walls.
From Frome to Warminster, Trowbridge and Bath, the same survey-first process applies: measure, specify, fix the price, then fit.

Do you need permission in Frome?
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.

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.

Larger panes go up with a vacuum lifter, a hoist or a crane. We plan access at survey.
