Glass links & glass box roofs in Carrickfergus: what is involved?
We handle glass links & glass box roofs across County Antrim, including Carrickfergus. In short: frameless glass links joining old and new buildings. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Bungalows are widespread in Northern Ireland, and sun tunnels or roof windows are an easy way to brighten internal hallways. In Carrickfergus, as anywhere, glass links & glass box roofs are the usual choice for joining a period house to a new extension or annexe.
From Carrickfergus to Newtownabbey, Bangor, County Down and Belfast, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Structural glass beams and fins
- Solar-control and low-iron glass
- Concealed gutters and drainage
- Heated glass on some systems
- Frameless or slim-framed glass

What to check first

Do you need permission in Carrickfergus?
Most rooflights on houses in Northern Ireland are permitted development under Class B, but not in a conservation area or on a listed building's curtilage. 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.
Technical Booklet F1 (2022) asks for replacement windows and rooflights in existing homes to reach WER Band C or a U-value of 1.6 W/m²K, assessed in the vertical position. Extensions follow a 25% glazing allowance in Technical Booklet F1.

Glass links & glass box roofs in Carrickfergus: questions
Do glass links need planning permission?
Often, yes — and listed building consent if either building is listed. We can provide drawings and product data for your application.
Is structural glass safe?
Structural glass is laminated so it stays in place if a ply breaks. The manufacturer designs it for the loads involved.
Can a glass link be warm enough to use all year?
With insulated glass units, solar control and good detailing, yes — though it will always be brighter and more exposed to temperature swings than a solid room.
How do I book a survey in Carrickfergus?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Carrickfergus?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
