laminated glass for large aquarium and delamination

I am currently busy with the construction of a large aquarium of 5000 litres,Having done this before with another aquarium i have witnessed in most aquariums using laminated glass that over some time the glass begins to delaminate in 3 different ways along the edge, it either get small finger like projections that look like clear glue or it get an air bubble which forms and gets squeezed due to changes in the pressure and looks almost like a crack and lastly it begins to absorb moisture into the laminate with water condensation forming in it.

Butt Joined Glass Silicon Joint Size

Is there a minium/maximum width for silicon joint in butt jointed glass ??

Project glass support steelwork has theoretical mid span deflection of 21mm over 9000mm span after the glass is installed (ie: due to live loads)and floor is occupied. If we use standard 6-10mm joints then there is a danger that the glass joint will pinch at top of joint. Any ideas to deal with the this potential issue ?

Canadian Glass Standard

I run a small fab shop with most of jobs being the glass jobs. Since I am a small player, the supplier has been bumping up the price since they know I don’t have much bargain power. It is eating away my profits big time. I am thinking to import glass from somewhere else, mostly likely China. I understand that the glass in Canada needs to comply with the CGSB. For example, the tempered glass needs to be stamped to say it complies with CAN/CGSB 12.1.M. How does it work with imported glass?

Thanks

Need help finding a certain specialty tool for glass removal.

I am looking for a special glass removal tool and have searched the web for hours with no luck. The tool I'm after kinda looks like a inverted pizza cutter with a large plastic base. The tool is used for cutting the seal or glazing tape that holds the glass into the window frame. If anybody knows what I'm talking about and can point me in the right direction it would be appreciated.

Thanks.
