Questions from Derry
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.
Is it worth having solar-control glass in Derry?
With the midsummer sun about 58.4° high at noon, roof glass in Derry gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Who checks building regulations for a lantern in Derry?
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.
