Glass links & glass box roofs in Barry: what is involved?
We handle glass links & glass box roofs across South Glamorgan, including Barry. In short: frameless glass links joining old and new buildings. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Glass links & glass box roofs suit listed and period buildings where the old wall should stay visible.
From Barry to Dinas Powys, Penarth and Cardiff, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Barry
- Solar-control and low-iron glass
- Frameless sliding or pivot doors

Before you order: points to check
- Abutments with old masonry need careful weathering
- Structural calculations are part of the design
Do you need permission in Barry?
Planning rules in Wales are tighter than in England for rooflights: Class C rights do not apply in conservation areas, National Parks or AONBs, so a rooflight there needs planning permission. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
Welsh Building Regulations expect new or replacement rooflights to reach 2.2 W/m²K and roof windows 1.4 W/m²K or a Band B rating. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.
Read the planning permission guide before you commit to a design.

Common questions
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.
How is the glass joined to the old wall?
Usually by a slim channel or flashing set into the masonry, sealed and weathered so the old wall can move without cracking the glass seal.
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 Barry?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Barry?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
