B12610405 Polycoolite™ TwinWall Panel 8mm, 4' x 5'


SALE: $61.25

Reflects Excess Heat

Here is an insulated glazing panel specifically designed for growing plants. It transmits the visible light spectrum that plants use, but reflects enough infrared (heat) spectrum to cool a greenhouse 7° F to 14° F in summer. R = 1.7.

The pearlescent exterior coating contains a reflective pigment. This reduces the need for exterior shade panels, and increases available light for plants. Recommended for use where summertime overheating is a problem. Install in roof, optionally in west wall. Interior surface has anti-fog coating. 10-year mfg. warranty.

Panels are 5/16" thick (8 mm)
4' x 5'(Dimensions + or - 1/8")
Growing spectrum light transmission 60%

CRATING Polycarbonate Panels: Add $50 crating charge. Shipped by motor freight - please call for rate. Smaller sizes cut to order. Allow approximately 3 weeks for delivery.

See Shipping Note to left.
