FREIGHT CHARGES VARY. Once your order is placed, we will contact you with the cost of shipping.

These Poly Shutters are the same quality as our Poly Long Life Shutters (#300720), but include a 3/4" styrofoam board. Slide it in place and watch your fuel bills drop. (Color of styrofoam may vary.)

Made to withstand the elements and are completely corrosion resistant. Keep your barn warmer and isolate your fans from the high moisture and corrosive environment on the inside of your building. When warmer weather finally arrives, simply remove the insulation board and your fans are ready for use.


  • Poly shutter blades and frame are made from rigid exterior grade poly
  • Stainless steel pivot rods run the entire length of the shutter
  • Shutter blades are curved to open easier and seal tight when closed
  • Reinforced stainless steel corners for superior strength
  • Designed for agricultural use only

Area "C" indicates shutter size; see the photo under "More Views."

    This is a great product which you could also slide in a filter instead of the foam. Solid construction.
