Looking to replace a broken pane of glass and checking prices on Google I noticed plenty of suppliers quoting for 4mm clear float and 4mm clear toughened. And giving instructions on how to price a particular cut size.
However when checking out toughened glass on Google there it's claimed (as I'd always thought to be the case) that " Any cutting or grinding must be done prior to tempering. Cutting, grinding, sharp impacts and sometimes even scratches after tempering will cause the glass to fracture."
So are there various kinds of "toughened" (as opposed to laminated which is thicker) 4mm glass ?
