Glazing Systems:
twinwall polycarbonate glazingTwinwall Polycarbonate - This 6mm polycarbonate is among the most economical glazing materials.  It is practical for a growing greenhouse as it offers 50% more insulation than single pane glass while diffusing excess sunlight in the summer. It is virtually unbreakable, making it safe and an ideal roofing material. The polycarbonate provides an R value of 1.59 and has about 82% light transmission, helping to minimize interior condensation.

Optional Accessories:
