Frameless structural rooflights in Sherborne: what is involved?
Thinking about frameless structural rooflights in Sherborne? 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Think of frameless structural rooflights for rooms where you want sky without a visible frame.
Sherborne sits about 8 km from Yeovil and 26 km from Dorchester, and we cover the whole DT9 postcode district and the roads in between.

Planning and building rules for Sherborne
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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.

Common questions
How is it lifted onto the roof?

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.

Yes — it is structural glass designed for the job. The support is hidden rather than missing.
