Questions from Grantham
Is a contemporary lantern the same as a flat rooflight?
No. A contemporary lantern still has sloping glass and a ridge or apex; it simply has slimmer frames and fewer bars. A flat rooflight is a single, nearly flat pane of glass on an upstand.
Can I have a contemporary lantern in white?
Yes, though most buyers choose grey or black because the slimmer frame is the point and dark frames disappear against the sky.
Can you fit a roof lantern in Grantham?
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.
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.
