Square roof lanterns for Cardiff homes
Four triangular panes meeting at a point: a pyramid lantern for square openings.
In midsummer the noon sun stands about 62.0° high over Cardiff, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Strong central focal point from below
- Ideal over a table, island or hallway
- No ridge, a neat apex cap instead

Planning and building regulations for Cardiff
Rooflight energy standards in Wales come from the Welsh Approved Document L (2022), so check figures quoted for England do not get used by mistake.
Permitted development rules in Wales are set separately, so check with your council, especially for listed buildings and conservation areas.
Building regulations in Cardiff are checked by your local authority building control team. Replacing a rooflight in an existing home is building work in Wales too. A competent person scheme installer can self-certify; otherwise building control should be notified.

Questions from Cardiff
Will a square lantern leak at the top?
It should not when it is correctly installed and maintained. The apex is factory-designed to shed water; leaks usually come from the upstand or roof membrane rather than the lantern itself, which is why the upstand detail matters.
Can I have an opening vent in a pyramid lantern?
Some ranges can fit a vent in one of the triangular panes, others cannot. We will tell you on the quote whether your chosen range allows it.
Do you deliver roof lanterns to Cardiff?
Yes. Delivery to Cardiff (CF10) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
Is it worth having solar-control glass in Cardiff?
With the midsummer sun about 62.0° high at noon, roof glass in Cardiff gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
