Questions from Willesden
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.
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.
Is it worth having solar-control glass in Willesden?
With the midsummer sun about 61.9° high at noon, roof glass in Willesden gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
