Aluminum Frames

Our greenhouses are built with an aluminum frame which can include trusses, roof purlins, support braces which meet 85 mph winds and 32 psf snow loads. They are typically 30-50% heavier than our competition. We offer a unique service to upgrade the greenhouse to sustain higher loads if necessary and can increase snow loads to over 100 psf and wind loads to meet 140 mph winds which is equal to a category 1 hurricane.

Our aluminum frames are proprietary to us – alloy and temper framework is 6063-T5 or T6 for extrusions and 209 for sheet/plates. Each roof purlin can carry a 50 pound hanging basket!

Aluminum: Alloy and temper framework is 6063-T5 or T6 for extrusions and 209 for sheet/plates.
Paint: Typical finish and trim is semi-gloss baked on Duracron enamel finish to comply with AMMA 2603 specification. Other coatings are available.
Gaskets: Poly Vinyl Chloride 15 lb density double sided adhesive gasket.
Extrusions: The glazing bars are proprietary solid extrusions that incorporate internal and external weep channels to direct moisture to the exterior of the greenhouse.
Fasteners: Non-magnetic, non-corrosive stainless steel compatible with aluminum.
Venting: Every greenhouse is built with individual 20” x 48” solar automatic roof vents for ventilation. Continuous larger roof venting available.

Glazing

We offer many options including single tempered glass, tempered insulated double glass, twinwall polycarbonate, and fivewall polycarbonate. For those customers wanting a living and growing space, we also offer tinted, high performance and laminated glass. All glazing options can be intermixed in the same greenhouse.

SINGLE GLASS:

Single glass makes for a nice show piece in your yard. Our single glass is tempered safety glass to minimize any possibility of breakage or injury. Glass appeals to gardeners who want full light transmission to control the amount of sun in the greenhouse.

Single Glass 3MM, Insulating R-Value .96 Approximately 95% light transmission.

DOUBLE GLASS:

Insulated double glass maintains superb heat insulation for all types of growing. Our double glass is tempered safety glass to minimize any possibility of breakage or injury.

Double Glass 16MM, Insulating R Value 2.1 Approximately 90% light transmission. Optional high performance Low E glass (R Value) Heat Gain = 3.45. Approximately 70% light transmission.

TWINWALL POLYCARBONATE:

Our 6mm twinwall polycarbonate is the most economical. It is a practical choice for a working greenhouse as it offers 50% more insulation than single pane glass and diffuses harmful sunlight in the summer. It is essentially unbreakable, making it very safe in a family environment. The insulation will prevent the temperature in the greenhouse from changing drastically and results in the best possible growing environment.

Twin Wall 6MM, Insulating R-Value 1.62. Approximately 82% light transmission.

FIVEWALL POLYCARBONATE:

Our 16mm fivewall polycarbonate is the most energy efficient glazing available on the market today. It offers 50% more insulation than double glass and 80% more insulation than twinwall polycarbonate. Fivewall is ideal for colder climates and gardeners who grow specialty plants, or for those who wish to reduce long term heating costs.

Fivewall 16MM, Insulating R Value 3.0. Approximately 62% light transmission.
