Questions from Winchester
Can I replace polycarbonate panels with glass?
Usually not in the old frame: glass is much heavier than polycarbonate and the frame was not designed for it. Replacing the whole lantern is the safer route.
Will a new lantern be warmer?
A modern double glazed lantern with a thermally broken frame loses far less heat than polycarbonate.
Can you fit a roof lantern in Winchester?
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 Winchester?
With the midsummer sun about 62.4° high at noon, roof glass in Winchester gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
