How we approach frameless structural rooflights in Daventry
For Daventry 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.
Industrial and commercial units around Midlands towns often still have their original rooflight sheets, which are due for replacement. In Daventry, as anywhere, frameless structural rooflights are the usual choice for architect-led extensions and long slots of light over islands or along party walls.
From Daventry to Rugby, Towcester and Northampton, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Triple glazing
- Solar-control coatings
- Heated glass on some ranges
- Shadow-gap or plastered reveal
- Low-iron extra-clear glass
- Double or triple glazed structural units
- Nothing but glass visible from inside
Things we check at survey
- The internal finish (plaster, shadow gap) is agreed before order
- Large panes need lifting gear and access planning
Planning, building control and Daventry
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.
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. 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.

Frameless structural rooflights in Daventry: 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.
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.
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 the survey in Daventry free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Daventry?
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.
