Roof lanterns for Porthcawl: the essentials
For Porthcawl homes and buildings we offer roof lanterns: hipped glass lanterns that lift the ceiling of orangeries and extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. In Porthcawl, as anywhere, roof lanterns are the usual choice for orangeries, kitchen-diners and single-storey extensions.
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.
Specification options
- Internal and external colours
- Solar-control or self-cleaning glass
- Opening vents with electric control
- Rectangular, square or bespoke sizes
- LED lighting in the plaster box
- Can include opening vents
- Double or triple glazed with solar-control options
Before you order: points to check
- Larger lanterns may need a steel or timber ring beam
- Needs a strong, level kerb or upstand
Planning and building rules for 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.

Questions about roof lanterns in Porthcawl
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
Do they leak?
Modern lanterns are sealed systems. Leaks usually trace back to the kerb or roof membrane detail, which we form and check ourselves.
Roof lantern or flat rooflight?
A lantern adds height and sky from all sides; a flat rooflight is lower-profile and cleaner from outside. Our guide compares them in detail.
