Frameless structural rooflights in St Albans: what is involved?
Our frameless structural rooflights service in St Albans covers minimal glass rooflights with no visible frame from inside. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Typical uses for frameless structural rooflights include architect-led extensions and long slots of light over islands or along party walls.
We work across Hertfordshire, including St Albans, and in neighbouring towns such as Harpenden and Hatfield. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Shadow-gap or plastered reveal
- Heated glass on some ranges
- Low-iron extra-clear glass
- Triple glazing
- Butt-jointed runs for long openings
- Nothing but glass visible from inside
- Clean modern detail for architect-led schemes
Things we check at survey
- The internal finish (plaster, shadow gap) is agreed before order
- Tolerances are tight — the opening must be built square and to size
Consents for frameless structural rooflights in St Albans
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.
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.
Read the planning permission guide before you commit to a design.

Common questions
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
Is frameless glass as strong as a framed rooflight?
Yes — it is structural glass designed for the job. The support is hidden rather than missing.
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.
Is the survey in St Albans free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in St Albans?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
