Questions from Egham
Do bespoke lanterns cost much more?
For simple rectangles the premium over a stock size is usually modest. Special shapes cost more because each one is engineered individually.
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.
Is it worth having solar-control glass in Egham?
With the midsummer sun about 62.0° high at noon, roof glass in Egham gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
