Questions from Fort William
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.
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.
Is it worth having solar-control glass in Fort William?
With the midsummer sun about 56.6° high at noon, roof glass in Fort William gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
