What do frameless structural rooflights in Altrincham involve?
For Altrincham 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.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Think of frameless structural rooflights for architect-led extensions and long slots of light over islands or along party walls.
We work across Greater Manchester, including Altrincham, and in neighbouring towns such as Sale and Urmston. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Heated glass on some ranges
- Butt-jointed runs for long openings
- Triple glazing
- Shadow-gap or plastered reveal
- Low-iron extra-clear glass
- Long, slim or very large formats
- Can run along party walls and side returns
Before you order: points to check
- Large panes need lifting gear and access planning
- Tolerances are tight — the opening must be built square and to size
Consents for frameless structural rooflights in Altrincham
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.
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. 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.

Questions about frameless structural rooflights in Altrincham
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
Can a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
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.
Will I need planning permission in Altrincham?
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.
Can you work alongside my builder in Altrincham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
