Questions from Harwich
How accurate do my measurements need to be?
Accurate to the millimetre on the outside of the kerb, measured at several points. Kerbs are rarely perfectly square, so measure both diagonals too. Our measuring guide shows how.
Will I see a drawing before it is made?
For made-to-measure and special shapes, yes: the order is based on a drawing you approve, so the size you check is the size that gets made.
Is it worth having solar-control glass in Harwich?
With the midsummer sun about 61.5° high at noon, roof glass in Harwich gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
