Laminated Glass fabrication parameters

Hi everyone, this is my first post on this forum.

I'm a mechanical engineer at Dialum S.A. a glass manufacturer company in Chile. Here we receive crude glass and process it to the final costumer and bring them all kind of windows and doors, from simple pulish glass to anti-huracan dvh with tempered laminated glass.

In this opportunity I'm writing here to discuss with you guys a problem I'm working on at the company. It concerns to the laminated glass line. Specifically at the de-airing zone.

How can I roughtly calculateTempered glass horizontal spans

I am contemplating replacing Lexan panels on a patio cover with tempered glass and need a reasonable starting point for the spans allowed by various thicknesses of the glass.  My spans are approx. 4ft between continuous frames and load lengths of approx. 50" and 80".  Any accessible calculators on line or knowledgeable suggestions welcomed. Wind zone is 120mph, no high exposure rating. Thanks

Frameless glass balustrade on spigot. Height 1350mm


We need advice with a frameless glass balustrade we have been asked to supply and install. 

Job is in qld, Australia.  

Glass, 12mm toughened. Fix to slab with 2 x core drill stainless steel spigots. Handrail to bolt through glass and tie into walls. 


The developer and architect want the finished glass height to be 1350mm . 

The spigot supplier only has calculations to a glass height of 1200mm. 

We are in need of someone to advise or calculate if we can go to 1350mm high. 

We have test results for the spigots if thay helps.
