Questions from Crawley
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.
Is it worth having solar-control glass in Crawley?
With the midsummer sun about 62.3° high at noon, roof glass in Crawley gets strong summer sun. Solar control is recommended for large or south-facing lanterns.

We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
