Questions from Castlereagh
Is self-cleaning glass the same as solar-control glass?
No. Self-cleaning is a coating that sheds dirt; solar control reduces heat gain. Many lantern units combine both.
Does it work under trees?
Less well. Sap and leaf debris build up faster than daylight and rain can deal with them, so lanterns under trees need more regular rinsing.
Is it worth having solar-control glass in Castlereagh?
With the midsummer sun about 58.9° high at noon, roof glass in Castlereagh gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Who checks building regulations for a lantern in Castlereagh?
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.
