Questions from Carrickfergus
Does a longer lantern need extra support?
Long lanterns use intermediate rafters inside the lantern itself. The roof structure around the opening must be designed to carry the lantern's weight; your builder or engineer sizes the trimmers.
Can a rectangular lantern be made to an exact size?
Yes. Made-to-measure lanterns are built to the external kerb size you give us, usually in 10 mm steps within the range's limits. Made-to-measure takes longer than a stock size and cannot be cancelled once ordered, so measure twice.
Do I need planning permission for a roof lantern in Carrickfergus?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district council before ordering.
Is it worth having solar-control glass in Carrickfergus?
With the midsummer sun about 58.7° high at noon, roof glass in Carrickfergus gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
