I am designing a glass roof over an unheated space. My glass supplier cannot give me deflection information for various types of glass. Where do I find such information so that I can have the carrying beams sized? I can figure snow loads and I know the length and width of each glass panel. Should I assume that I will be using a sandwich of tempered glass over laminated glass even though I do not need the insulating properties?

Pls tell me the formula for calculation of the deflection in glass to be used in a fixed / openable window.

If you need some support on glass design you should try Glass Thickness Calculator (

There you can design glass panes for several types of use.
