Questions from Gainsborough
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.
Do I still need to clean self-cleaning glass?
Occasionally. It keeps the glass cleaner for longer, but heavy dirt and droppings still need a gentle rinse, especially in dry spells.
Who checks building regulations for a lantern in Gainsborough?
Your local authority building control team or a registered building control approver. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
