Questions from Briton Ferry
Do large lanterns overheat a room?
A large area of south-facing glass can make a room warm on sunny days. Solar-control glass, an opening vent and good background ventilation all help. Our guide on overheating explains the options.
Does a large lantern need structural calculations?
The roof structure around it usually does. Your engineer or building control body will want the lantern's weight and the opening size.

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 SA11.
Is it worth having solar-control glass in Briton Ferry?
With the midsummer sun about 61.8° high at noon, roof glass in Briton Ferry gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
