Large roof lanterns in County Down: questions
What is the biggest roof lantern you can supply?
It depends on the range. Some go to about 6 m by 4 m with intermediate rafters. Send us your kerb size and we will confirm what can be made.
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.
Who checks building regulations for a lantern in County Down?
Your district council's building control service. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
