Mike Lamb Posted February 25, 2012 Report Share Posted February 25, 2012 The thermal pane window next to this bathtub is marked as tempered glass. The exterior glaze is cracked with a BB hole in it. The glass would crumble if it were tempered. Correct? Is only the interior glazing required to be tempered?

Jim Katen Posted February 26, 2012 Report Share Posted February 26, 2012 If it borders a tub or shower the inboard and outboard panes are both required to be safety glazed. There is an exception for outboard panes, but it doesn't apply to windows bordering tubs or showers. It says that the outboard pane in an insulated glass unit is exempt from the safety glazing requirement if its bottom edge is more than 25 feet above grade, a roof, walking surfaces, or other horizontal surfaces adjacent to the glass. This exception only applies to glazing that's more than 9 square feet in area, that has a bottom edge that's less than 18" from the floor, and a top edge that's more than 36" above the floor and that's near a walking surface. If one of these glazed areas is near a door or over a tub or shower, then the exception doesn't apply. Quote Link to comment Share on other sites More sharing options...
Mike Lamb Posted February 26, 2012 Author Report Share Posted February 26, 2012 Thanks. It seems deceptive practice. This window is made by ClimateGuard of Chgo. Home Depot sells them, I think or used to. I consider ClimateGuard a good cheap window. Quote Link to comment Share on other sites More sharing options...
