What do frameless structural rooflights in Andover involve?
Thinking about frameless structural rooflights in Andover? 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Frameless structural rooflights suit architect-led extensions and long slots of light over islands or along party walls.
Andover is around 35 km from Southampton, and we survey and fit throughout that part of Hampshire, including the SP10 district.
Specification options
- Shadow-gap or plastered reveal
- Butt-jointed runs for long openings
- Triple glazing
- Solar-control coatings
- Low-iron extra-clear glass
- Can run along party walls and side returns
- Nothing but glass visible from inside
Before you order: points to check
- Tolerances are tight — the opening must be built square and to size
- The internal finish (plaster, shadow gap) is agreed before order
Consents for frameless structural rooflights in Andover
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.
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.
