Questions from Derry
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 Derry?
Yes. Delivery to Derry (BT47) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
Do I need planning permission for a roof lantern in Derry?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district council before ordering.
