Questions from Grangemouth
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.
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.

Your local authority building standards (verifier) service. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
