Questions from Grantham
Will white uPVC yellow over time?
Modern uPVC profiles are UV-stabilised and should stay white with normal cleaning. Very old lanterns, especially with polycarbonate panels, are the ones that discolour.
Is uPVC heavier?
Weight is dominated by the glass, so the difference is small.
Is it worth having solar-control glass in Grantham?
With the midsummer sun about 60.5° high at noon, roof glass in Grantham gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Do I need planning permission for a roof lantern in Grantham?
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.
