Square roof lanterns for Caernarfon homes
Four triangular panes meeting at a point: a pyramid lantern for square openings.
In midsummer the noon sun stands about 60.3° high over Caernarfon, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Four triangular panes to a single apex
- Square sizes from about one metre
- Ideal over a table, island or hallway

Questions from Caernarfon
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.

Yes. Delivery to Caernarfon (LL55) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
Can you fit a roof lantern in Caernarfon?
