     (C) Standard roof pitch is 6" rise, to each 12" of width, 1:2, or 26-1/2 degree roof pitch above horizontal. A 1:12 mot pitch also available.

     (C) SECONDARY SUPPORT GLASS RECEIVING MEMBERS: To be structural aluminum alloy 6061-T6 or 6005-T5 with a rating of 35,000 psi yield. All other non-load bearing secondary aluminum extrusion framing members may be 6063-T6 with a rating of approximately 25,000 psi yield.

Bobs to be hot dip zinc galvanized steel. Grade 5 bolts to be furnished in high strength locations. Bolts below 1/4" in diameter may be aluminum or stainless steel. All screws to be hot dip zinc galvanized or stainless steel.

     (A) Glass to be bedded in extruded, cross-linked butyl rubber bedding (min. spec.  AAMA804.1 Fed. Spec. TT-C-1796A, Type II Class B) as furnished on Winandy SUN-MATE greenhouses or equal.
     (B) Butyl rubber caulking as supplied on Winandy SUN-MATE greenhouses or equal to be furnished for sealing the top of the glass along side of the roof rafter tongues on the roofs after the glass is laid in place before full-length aluminum caps are screwed in place (Fed. Spec. TT-S-001657.)
     (C) Clear silicone caulking sealer as manufactured by General Electric, Dow Chemical, or equal to be furnished for the filling and sealing of all the 3/4" extenor glass laps on the roofs, and exterior walls as exterior tempered glass is installed in to place (ASTM and Fed. Spec. TT-S- 00230C/ASTMC-920TT-S-001543A Type II Class A.)
     (D) Aluminum caps to be full-length and lap with and secure glass. Caps to be minimum .032" thick #3003-H14 work hardening aluminum alloy.
     (E) If structured plastic panels to be furnished, EPDM rubber seals to be furnished under the aluminum cap and sealing on the top of the structured plastic panel after panels are laid in place.

Structured plastic panel to be LEXAN+ polycarbonate by General Electric or equal or acrylic structured plastic panels as approved by owner or architect for longevity, flammability, maintenance, light transmission or resistance to structural damage.

Structured plastic panel manufacturers full specification and warranty must be submitted to owner. Warranty must at least be equal to the presently available limited 10 year warranty furnished by major manufacturers of structured plastic panels, such as LEXAN by General Electric Company.

(NOTE: Structured plastic panel - glass system must be convertible to one, two, or three tempered safety glass skin when owner may wish to convert to tempered glass skin in the future without needing to replace roof rafters and skin support structures.)

(NOTE: Structured plastic panels should not be installed on north/south ridge oriented greenhouses. To got maximum benefits of the sun through the outer and inner skin of the structured plastic panels, the sun must strike the panels at approximately 90 degrees, so the structural vertical walls do not interfere. The low angle of the winter sun will prevent the 90 degree entry angle almost all day long on north/south ridge oriented greenhouses. East/west ridge oriented greenhouses only present a similar problem in the first quarter of morning and the last quarter of the afternoon.)

     (A) ROOFS: Exterior glass on roofs to be 1/8" clear tempered safety glass.
