In an era of ever increasing energy costs the Traditional Fivewall Polycarbonate Greenhouse is one of the most energy efficient hobby greenhouse kits on the market. In addition to exceptional durability, the 16mm thick polycarbonate panels offer four separate dead air spaces to insulate your greenhouse from cold outside air. This results in an amazing R value of 3.03 and a 50% decrease in energy required to heat this greenhouse when compared to standard 6mm polycarbonate. The Traditional Fivewall features a green or white heavy duty aluminum structure, 16mm 5 wall polycarbonate covering, extra high sidewalls, and double wide roof vents.

Survived 10 years in harsh north Idaho.

I installed the 12 X 20 5 wall greenhouse in 2012. Went together well. We live in a zone 4-5 area and have pretty significant show in the winter. The greenhouse has survived all northern Idaho can throw at it. And this includes some pretty nasty windstorms. I definitely would buy again and can recommend this to anyone needing an strong structure. It has greatly increased my gardening enjoyment/productivity since this climate is quite challenging.
