Laminated panel

Hi everyone
what is the process of Laminated panel.

Does it a kind of clear decal which is put on the back of the glass ?
Is it enough to make the fusing process , in a big unit, to safe to use in a architecture

Thanks

I made a panel using float glass that is laminated and meets hurricane specification. I set up my sandcast mold, placed a sheet of 10mm glass on it. Then I sifted alumina hydrate on top of that glass. Then I placed another layer of 10mm on top of that. I kiln cast both pieces of glass together. This way the perimeters were perfectly aligned. The alumina took up the space that is replaced with resin.

The laminating process is to seal the edges with clear VHB tape, then wrap with aluminum duct tape, and/or silicone. You leave 2 holes at the top, one to pour resin in and one for air to escape out. You need a tilt table and some clamps to get this all done right. When the resin sets up, the glass is laminated and meets safety glass codes. You have to use a low contraction resin. The standard resin used in the industry, has a high contraction factor. Low contraction resins are made in both the USA and Europe.

I had this done by a company with plenty of practice at it. I have done this myself, but found the learning curve steep and the puddle of leaked resin on the floor to be nasty. There are a lot of tricks to getting this done right.
