What do frameless structural rooflights in Kettering involve?
We handle frameless structural rooflights across Northamptonshire, including Kettering. In short: minimal glass rooflights with no visible frame from inside. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Industrial and commercial units around Midlands towns often still have their original rooflight sheets, which are due for replacement. Typical uses for frameless structural rooflights include rooms where you want sky without a visible frame.
Kettering sits about 11 km from Wellingborough and 11 km from Corby, and we cover the whole NN16 postcode district and the roads in between.
What you can choose
- Shadow-gap or plastered reveal

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 Kettering
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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. 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.

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 it open?
Some frameless designs include a sliding or hinged opening element, but most are fixed. Pair with an opening unit if you need ventilation.
Can a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
Do I need to be at home for the survey in Kettering?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Kettering?
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.
