We use only 1/4″ glass, either laminated or tempered, as specified. Glass this thick takes a pretty heavy blow to break, unlike competitors who utilize 1/8″-thick glass with their doors. Further, our 1/4″ laminated glass offering is extremely difficult to break thru to gain access. It is the same type of glass utilized on the windshield of an automobile. It is made to stay together rather than break apart into small pieces like tempered glass. All that said, if you check with your local police department you will find few “break-ins” or burglars gaining access to a home through a front facing garage door. Side and rear windows and doors are much more prevalent break-in entry points.
