Is triple glazing heavier to lift?
Yes, the glass is roughly 45% heavier. Plan for extra hands or lifting equipment on larger lanterns.
Do I need triple glazing to meet building regulations?

Do I need planning permission for a roof lantern in Altrincham?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district, borough or unitary council before ordering.

With the midsummer sun about 60.1° high at noon, roof glass in Altrincham gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
