Glass links & glass box roofs in Porthcawl: what is involved?
For Porthcawl homes and buildings we offer glass links & glass box roofs: frameless glass links joining old and new buildings. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Typical uses for glass links & glass box roofs include listed and period buildings where the old wall should stay visible.
Jobs in Porthcawl are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Concealed gutters and drainage
- Heated glass on some systems
- Frameless or slim-framed glass
- Frameless sliding or pivot doors
- Solar-control and low-iron glass
- Visually light connection between buildings
- Can include frameless doors
Things we check at survey
- Structural calculations are part of the design
- Thermal performance of large glass areas must be calculated
Planning, building control and Porthcawl
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.
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. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.
See our building regulations guide for U-values, glazing limits and self-certification.
