How we approach frameless structural rooflights in Crowthorne
For Crowthorne homes and buildings we offer frameless structural rooflights: minimal glass rooflights with no visible frame from inside. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. In Crowthorne, as anywhere, frameless structural rooflights are the usual choice for architect-led extensions and long slots of light over islands or along party walls.
Jobs in Crowthorne are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Options we can specify in Crowthorne
- Shadow-gap or plastered reveal
- Triple glazing
- Low-iron extra-clear glass
- Heated glass on some ranges
- Solar-control coatings
- Can run along party walls and side returns
- Clean modern detail for architect-led schemes
Things we check at survey
- Tolerances are tight — the opening must be built square and to size
- Structural glass specification comes from the manufacturer
Do you need permission in Crowthorne?
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. 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.
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.
