Frameless structural rooflights for Borehamwood: the essentials
Thinking about frameless structural rooflights in Borehamwood? 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.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Think of frameless structural rooflights for architect-led extensions and long slots of light over islands or along party walls.
Neighbouring towns include Barnet (5 km) and Bushey (6 km). We offer a survey date when we reply to your enquiry.
What you can choose
- Shadow-gap or plastered reveal
- Low-iron extra-clear glass
- Solar-control coatings
- Heated glass on some ranges
- Butt-jointed runs for long openings
- 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
- The internal finish (plaster, shadow gap) is agreed before order
Do you need permission in Borehamwood?
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Common questions
How is it lifted onto the roof?
Larger panes go up with a vacuum lifter, a hoist or a crane. We plan access at survey.
Can a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
