Questions from Borehamwood
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.
Will triple glazing stop rain noise?
It reduces it noticeably. Laminated glass reduces it further.
