Hi all, was wondering if anyone else has ever had this happen. Yesterday I was getting my trailer ready to take a mare to the vet so I opened the roof vents and then proceded to open the bus windows on the hip. When I got to the second window (3 horse) it shattered before I even got it all the way open. It didn't feel "sticky" when I slide it open, it just shattered as it pulled away from the gasket.

Needless to say glass fell all over my mare face since she was tied directly underneath and it spooked her so bad that she broke the tie on the trailer too.... she is usually a bomb proof mare, but the noise was so loud like a bullet had it the window.

We had a low temp in the morning of 43 and when I was getting ready to load the mare it was 82. Don't know if the temp contrast in the trailer caused it to shatter.

Now it looks like I can't purchase the window glass piece, but the whole bus window assemby.

Tempered plate glass... It happens. Had one spatter in my Gore last winter, started sliding it and it exploded when it got about half way.... Still finding little pieces in the DR carpet.

The trailer was less than a year old. Mfg. replaced the broken window free of charge. Any glass shop can cut a window to size. This window was in the bulk head wall betwen the DR and horse area....

We had one half of the window above our sofa burst one afternoon (the stationary side...not the side that slides)  No idea why.  Trailer had been parked for several months.  Hadn't been mowing to throw stones....No evidence of a bird....Hadn't been terribly windy.  No idea. 

We were told the same thing by Sundowner...can only buy the whole assembly.  Hubby didn't want to replace the whole thing.  Figured original was better. Replacement has better chance to leak.  He cut a piece of plexiglass to fit and plans to give that to glass place as a template to get tinted tempered glass replacement.
