Glass door weight calculator
Enter the leaf size and glass thickness to get the weight of a frameless tempered glass door. That weight is the figure to size patch fittings and the floor spring against.
- Glass area per leaf
- 1.89 m²
- Glass weight per leaf
- About 57 kg
Add the handle and lock to this figure. Each leaf rides on its own floor spring, so size the spring for one leaf.
Questions buyers ask
How much does a glass door weigh?
Tempered glass weighs about 2.5 kg per square meter for every millimeter of thickness. A 900 by 2100 mm leaf in 12 mm glass is about 57 kg before the handle and lock.
Why does door weight matter for patch fittings?
On a frameless door the floor spring carries the leaf and the patch fittings hold the glass to it. Work out the leaf weight first, then ask for the rated door weight of the fittings and floor spring in writing.
Which glass thickness do your patch fittings take?
Our patch fittings list 8 to 12 mm tempered glass and most of our glass door pull handles list 10 to 12 mm. Check each part, because a set is only as wide as its narrowest part.
