Questions from Greenock
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.
Do I need planning permission for a roof lantern in Greenock?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your council before ordering.
How quickly can I get a roof lantern in Greenock?
