Framing sections between steel ribs shall consist of 5 vertical rows of glass on 8’ 5 ¼” centers or 4 rows at 6’9” centers for 25’ & 30’ wide. Sidewalls posts shall attach to perimeter foundation 8” above floor grade, 8” thick or 9” thick depending on width of greenhouse to the depth required by local conditions and practice. (24” high walls or higher for snow zones and special applications may be used). All bolt screws, nuts and other fasteners used in the greenhouse shall be galvanized, stainless, plated or aluminum as required by manufacturer.
Design Load
American Classic Greenhouses can be tailored to meet any current building code for wind load and/or snow load. Stamped engineering calculations are available. Foundation kneewall width may change with engineering.
Glazing
All glass shall be 1/8” double strength or 1/8” tempered glass. Roof glass is shingled with a 1/2” to 3/4” overlap, vertical glass shall be supported and separated by special vinyl extrusions. All glass shall be held in place with specially designed stainless steel clips. Glazing compounds used in the bedding of glass shall be butyl glazing tape with silicone caulking in certain areas. Clear insulated polycarbonate materials are available at additional charge. Insulated Glass is available at an additional charge but does not carry a warranty against seal break down.
Ventilation

Ridge vents are glazed with polycarbonate and are controlled by a thermostat and integrated into the overall climate control system. Side vents are available for special applications and shall be operated from a single point by a permanently lubricated worm gear driven chain vent machine that shall be manually operated.
Doors
Doors and frame shall be extruded aluminum shapes for hanging 1 ¾” thick tubular aluminum doors (1/ ¼” thick on smaller models). Doors shall be installed and pre-hung within 1 ¾” X 3” extruded aluminum framing at all openings to the size required.
Materials
- Sill Plate
- The sill plate shall be extruded aluminum shape approximately 2 ½” x 2”, permitting lateral security and sufficient adjustment to accommodate minor foundation irregularities.
- Steel Frame
- The hot-dipped galvanized steel frame is to be 3 X 4.1 channel. Welded 3/8” base plates to be secured to foundation with two anchor bolts each of the size specified on drawings.
- Purlins
- The purlins shall be an extruded aluminum shape specifically designed for greenhouse use, weighing 0.912 lbs per foot.
- Ridge
- The ridge shall be of extruded aluminum shapes designed to incorporate the ball and socket hinge for the roof vents, weighing 1.636 lbs per foot.
- Glazing Bars
- The glazing bars are an extruded shape weighing approx. 0.3 lbs per foot measuring- 1 1/8” x 1 ¼”, designed to receive stainless steel glazing clips.
Modifications
Adjustments to standard models are available upon consultation.
Erection
The erection and glazing of the greenhouse and setting of climate control equipment shall be as specified in the order.
