How we approach frameless structural rooflights in Berkhamsted
Thinking about frameless structural rooflights in Berkhamsted? 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. Typical uses for frameless structural rooflights include rooms where you want sky without a visible frame.
Neighbouring towns include Chesham (7 km) and Hemel Hempstead (8 km). We offer a survey date when we reply to your enquiry.

Consents for frameless structural rooflights in Berkhamsted
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. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
