Questions from Caernarfon
Do I need an upstand for a roof lantern?
Yes. Lanterns are designed to sit on an upstand, never directly on the roof deck.
Can I order a lantern before the upstand is built?
Yes, if you build the upstand to the lantern's stated external size. Many people order the lantern and upstand together so they match.
How quickly can I get a roof lantern in Caernarfon?
Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for LL55.
Is it worth having solar-control glass in Caernarfon?
With the midsummer sun about 60.3° high at noon, roof glass in Caernarfon gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
