What do frameless structural rooflights in Coleraine involve?
For Coleraine 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.
Northern Ireland has a mix of terraces, bungalows and rural farmhouses, and rooflights are a common upgrade when extending. Frameless structural rooflights suit architect-led extensions and long slots of light over islands or along party walls.
Coleraine is around 44 km from Derry/Londonderry, and we survey and fit throughout that part of County Londonderry, including the BT51 district.
Choices for your Coleraine project
- Butt-jointed runs for long openings
- Shadow-gap or plastered reveal
- Triple glazing
- Low-iron extra-clear glass
- Heated glass on some ranges
- Nothing but glass visible from inside
- Can run along party walls and side returns
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
Planning and building rules for Coleraine
In Northern Ireland, roof alterations come under Class B of the 2015 order: a rooflight facing a road must not project more than 15 cm and must sit at least 0.5 m from the ridge, eaves, verge and party wall. A side-facing window within 15 m of a neighbouring boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
For homes in Northern Ireland, Technical Booklet F1 sets 1.6 W/m²K (or WER Band C) for replacement glazing including rooflights. Extensions follow a 25% glazing allowance in Technical Booklet F1.

Frameless structural rooflights in Coleraine: questions
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.
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.
Can you work alongside my builder in Coleraine?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Coleraine?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
