Planning and building rules for Cwmbran
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Ridge & pitched glass roofs in Cwmbran: questions

Glass is quieter than polycarbonate. Triple glazing or laminated glass reduces rain noise further.

Yes, top-hung vents with electric actuators are common, often with a rain sensor.
Can it be partly solid?
Yes — part-glazed, part-insulated roofs balance light and heat.

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.
