I have six (6) large insulated commercial glass panels available for free pickup. The dimensions are 115 1/4" x 46 1/2" x 1" and they're tinted approximately 35%. They were removed from a commercial building 20 years ago - I believe it was a Burger King - and have been sitting in my garage (on wooden boards) ever since. There was no condensation or leaks between the glass panels at that time.
They're heavy and cumbersome so bring a trailer and a couple friends as I cannot help load. I'm available evenings and weekends.
help load 'em for a GL4X4 member.
