Questions from Penarth
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.
How is a large lantern delivered?
On pallets, usually with the frame and glass packed separately. The heaviest single item is normally a glass unit, which needs two or more people to lift safely.
Is it worth having solar-control glass in Penarth?
With the midsummer sun about 62.0° high at noon, roof glass in Penarth gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Do I need planning permission for a roof lantern in Penarth?
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.
