Weight

4mm glass weighs about 10kg per square metre, so a 1000 x 500mm pane is about 5kg.

How to measure

Give us the finished glass size. If the pane sits in a frame or against tiles, take 2 to 3mm off each edge as a fitting tolerance. We cut to a tolerance of plus or minus 2mm. Toughened glass cannot be cut or drilled after it is made, so check your sizes twice before you order.

Not for stoves

Stove and fire glass is a heat resistant glass ceramic, not toughened glass. Do not use this in a stove door: see stove glass cut to size.
