- Four triangular panes to a single apex
- Ideal over a table, island or hallway
- Stock colours or any RAL on request

Questions from Penarth
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.
What is the largest square lantern?
Ranges differ. Many go to around 3 m square, with extra hip bars on larger sizes. Tell us your kerb size and we will confirm which ranges can make it.
Do you deliver roof lanterns to Penarth?
Yes. Delivery to Penarth (CF64) 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 Penarth?
With the midsummer sun about 62.0° high at noon, roof glass in Penarth gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
