Questions from Chippenham
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 a pyramid lantern more expensive than a rectangular one?
Per square metre it can cost slightly more, because every pane is a triangle and the apex needs a special joint. The difference is usually small next to the effect of size and glass choice.
Is it worth having solar-control glass in Chippenham?
With the midsummer sun about 62.0° high at noon, roof glass in Chippenham gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
