Questions from Belfast
Will triple glazing stop rain noise?
It reduces it noticeably. Laminated glass reduces it further.
Do I need triple glazing to meet building regulations?
Not usually. Well-specified double glazed lanterns generally meet the limiting values for rooflights. Triple glazing is an upgrade, not normally a requirement. Your building control body can confirm for your project.
Do you deliver roof lanterns to Belfast?
Yes. Delivery to Belfast (BT1) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
Is it worth having solar-control glass in Belfast?
With the midsummer sun about 58.8° high at noon, roof glass in Belfast gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
