Have you heard of Fivewall Polycarbonate?
BC Greenhouses has been working with this glazing product for a few years. It was so impressive in terms of its energy efficiency that we built a new aluminum framing system to accommodate the wider profile. For example, a typical single glass greenhouse glazing is 3mm in thickness whereas the Fivewall polycarbonate is an impressive 16mm.
16 mm Fivewall polycarbonate offers light transmission of 62% and an R-value (thermal resistance of 3.03, meaning twice the insulating values of regular double glass. Strength in structure makes this material an ideal choice for areas subject to high winds. It is also an attractive-looking glazing option. As with any polycarbonate, Fivewall polycarbonate cleans easily with a mixture of dish soap and warm water applied with a soft cloth.
"We have been very pleased with the overall performance of the Fivewall polycarbonate on our greenhouses which are sold all across North America. It's definitely worth spending a bit more to achieve the combination of strength, beauty and energy efficiency."

Who would benefit from Fivewall?
Here is an example:
Tom lives in a colder climate that sees a significant amount of snow but he wants to grow citrus trees, orchids, and fox-gloves. A Cape Cod Fivewall polycarbonate was the perfect fit. Tom could maintain the night temperature of 55 F (13 C) with very little additional heat. The Fivewall polycarbonate glazing allowed for the best combination of light transmission and heat retention. The steep pitch of the roof causes the snow to simply slide off!
