Safe and Sound Glass

[Glasseye]

Laminated doorglass in the UK is fairly rare and the old type glass I have seen was always completely mounted in a frame which meant the glass was a standard laminated material without any toughening applied to it, but this glass has no frame and to make it work in an opening door glass they have semi-toughened it to withstand the operating stress placed on opening doorglasses. Something, an ordinary unframed laminated glass could never do.
