The Beauty's More Than Skin Deep.

Natural Gardening Company greenhouses are guaranteed to be free from defects in materials and workmanship for five years from the date of purchase. The polycarbonate glazing is fully warranted against excessive discoloration for the first five years. It has been in use in European greenhouses for more than 30 years with virtually no discoloration.

Double-Wall Polycarbonate Glazing -- The Best Greenhouse Glazing Material

• Virtually unbreakable polycarbonate is the same high-tech plastic used in aircraft windshields and helmets. Temperature extremes don't affect its impact resistance. Hail and baseballs bound off. Its impact strength is 30 times greater than acrylic and 200 times greater than glass. After glass, polycarbonate is the most flame resistant glazing

• Double-wall panels retain heat to help plants stay 10-20 deg.F warmer in winter. If you use a heater, you'll save 40% of the cost of heating a single-pane glass greenhouse.

• Design maximizes the quality of light for full, straight and even plant growth. Sunlight is scattered by the ribs between panel walls to surround plants without shadowing or burning them.

• UV-resistant additive in panels blocks 98% of the harmful UV rays while transmitting 83% of the visible rays that plants need for maximum growth. Plants are more productive. Glazing carries a 10 year limited warranty against hazing and discoloration.

• Panels won't crack or shatter. They may be cut with a fine toothed saw, allowing easy installation of plumbing or heating equipment.
