With a rain sensor the vent closes automatically. Without one it stays where you left it, so a sensor is worth having.
Does an opening vent let insects in?
When open, yes, as with any window. Some ranges offer fly screens.
Is it worth having solar-control glass in Ormskirk?
With the midsummer sun about 59.9° high at noon, roof glass in Ormskirk gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Who checks building regulations for a lantern in Ormskirk?
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.
