Glass links & glass box roofs for Briton Ferry: the essentials
Thinking about glass links & glass box roofs in Briton Ferry? The short answer: frameless glass links joining old and new buildings. The longer answer depends on your roof, which is why we survey before we price.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Glass links & glass box roofs suit listed and period buildings where the old wall should stay visible.
We work across West Glamorgan, including Briton Ferry, and in neighbouring towns such as Neath and Port Talbot. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Concealed gutters and drainage
- Frameless or slim-framed glass
- Solar-control and low-iron glass
- Heated glass on some systems
- Structural glass beams and fins
- Can include frameless doors
- Keeps period walls on show
Things we check at survey
- Structural calculations are part of the design
- Thermal performance of large glass areas must be calculated
Do you need permission in Briton Ferry?
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
See our building regulations guide for U-values, glazing limits and self-certification.
