What do frameless structural rooflights in Witham involve?
We handle frameless structural rooflights across Essex, including Witham. 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.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. Think of frameless structural rooflights for architect-led extensions and long slots of light over islands or along party walls.
From Witham to Maldon, Braintree and Chelmsford, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Butt-jointed runs for long openings
- Triple glazing
- Low-iron extra-clear glass
- Shadow-gap or plastered reveal
- Heated glass on some ranges
- Double or triple glazed structural units
- Clean modern detail for architect-led schemes
Before you order: points to check
- The internal finish (plaster, shadow gap) is agreed before order
- Large panes need lifting gear and access planning
Consents for frameless structural rooflights in Witham
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.
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

The process, step by step
- Tell us what you have. Send the CM8 postcode, a rough size and a couple of photos.
- Free site visit. For new installs we survey free, measure and confirm the roof detail.
- Agree the quote. You approve the specification and price before anything is ordered.
- Installation day. Usually one day into a prepared opening, longer for new openings.

Common questions
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 see the edge of the glass?
From inside, the reveal is finished up to the glass so the edge is hidden. From outside you will see the glass and its edge seal.
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.
Do I need to be at home for the survey in Witham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Witham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
