Opening roof lanterns in County Londonderry: questions
Can a vent be added later?
Usually not to an existing fixed lantern. Decide before ordering.
Does an opening vent let insects in?
When open, yes, as with any window. Some ranges offer fly screens.
Can I have a manual opening vent?
Manual vents are rare on lanterns because they are out of reach. Electric operation is standard.
Who checks building regulations for a lantern in County Londonderry?
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.
