Great seller.  Polycarbonate is the panel of choice for light panel in today's post frame and metal frame buildings.  MWI is the North American importer of Brett Martin.  Polycarbonate is a thermoplastic polymer which gives extreme high impact resistance and impressive durability.  Available is clear, soft white and opal.  Product is impact resistance from -40 to +210 degree without any significant distortion.   Polycarb cut's 98% of UV light.  We stock product to match the standard 36" panel with rib's 9" o.c. and some in the commercial R panel.

Also a big seller is a Polycarbonate ridge-cap which works in place of standard steel ridge cap and let's in a great amount of light.  24" wide x 10'6" long.
