I have been researching the different glazings I can use to recover my greenhouse next year. I don't want to recover it with film like I did this year. 4x8 sheets of polycarbonate are going from $41 to $60 a sheet!! My growers supply book I just got in is selling 4mm 4x8 sheets of polycarbonate for 41.95. I need 6 sheets to cover my geenhouse roof alone. I have been reading up on polyethylene sheeting that looks just like the twinwall polycarbonate, but is more flexable and sold in roles. I have seen one website that said polycarbonate is better. Then I read on another website that says polyethylene is better. I am sure the polycarbonate is better, I just need to know what are some of the drawbacks to using the polyethylene over the polycarbonate. I need something with regidity because I am getting some water pooling on the roof. Hopefully it is not going to do any harm till next years recover. Since I want next year to be the last covering for a while I am trying to decide the most economical and best covering without breaking the bank. I see many advantages to the polyethylene over the polycarbonate. Since it is only $23 a 6mm 4x8 sheet at growers supply. I just want to make sure some folks have not had bad experiences with polyethylene.
Also I can get 4mm for 14.69 per 4x8 sheet, and 6mm is 23.29 per 4x8 sheet. It is nothing for me to put a lining of 6mil poly sheeting on the inside for extra insilation during the winter months, but what would the more experienced growers recomend for a grower in GA. My temps rarely get below freezing and snow is a rarity. If it happens to snow it rarely lasts more than a day. Any and all advice is welcome.
Here is the link and upon further reading the alternative sold at growers supply is UV resistant polypropylene and not polyethylene. Even thought polyethylene as a covering is available. So really I need info on the differences in the three materials. Polycarbonate, polyethylene, and polypropylene.
