Questions from Pwllheli
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.
Can you fit a roof lantern in Pwllheli?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
Is it worth having solar-control glass in Pwllheli?
With the midsummer sun about 60.6° high at noon, roof glass in Pwllheli gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
