Title: Re: [nafex] glass

I have to admit this has been an extremely interesting discussion about glass.  Positively enlightening!  And for me, very timely as the snow here in Maine has just barely receded enough to reveal my cold frames which have had three feet of snow on them since February.  The snow receded to reveal broken panes in five of the nine 2'X4' lights.   The dogs walk over the frames when they are covered with snow and the wood frames twist and warp with the weather making replacing one or two panes each spring a seasonal ritual.

A short aside:  Last fall a bear came in the night and lifted two of the lights off the cold frame and set them aside and then got into the frame to browse the fall greens inside.  He left very clear prints in the soft soil.  I didn't begrudge him the greens because he didn't break any of the glass.

But just as I decided that I needed a tougher material than double strength glass this discussion started and it has been elucidating.  I have ordered some double wall polycarbonate from a farm supply place on the west coast.  It comes in 4'X8' sheets.  It seems relatively inexpensive although the shipping costs are horrendous. 

My question:  How does one cut the stuff?  With a circular saw?
