(Was: Re: PHOTOS - NYCT O7 6749 @ Earth Day Fair - setting, posted by (SIR) North Shore Line on Sat Apr 21 23:06:29 2007. It looks to me that the 'frameless' types in the pictures are of the bonded design, whereas the more normal type are held in by the rubber around the window. The difference when a window is broken is that a conventional framed-type pane can be replaced quickly - prise the rubber strips out, clean the remains of the window away and then fit a new pane of glass and refit the rubber.With the 'frameless' (i.e. bonded) glazing however, replacing a window equates to a couple of days out of service. This is because the glass is held in place by a bonding-type substance which needs to be mixed up, and then takes a day or two to cure properly. Until it's cured and the window is properly held in place, the bus must sit in the yard. This is the only reason I can think of - fitting conventional 'framed' windows equates to much less down time when a pane gets broken. |
