Questions from Cwmbran
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.
Do I need planning permission for a roof lantern in Cwmbran?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your county or county borough council before ordering.
Is it worth having solar-control glass in Cwmbran?
With the midsummer sun about 61.8° high at noon, roof glass in Cwmbran gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
