PATTERNS/MOLDS
1. Custom Pattern/Mockups: Patterns and mockups shall be hand carved and/or CNC machined by skilled pattern makers with minimum of ten (10) years experience with architectural elements. Patterns & mockups shall be available at manufacturing facility for architect’s inspection and approval before molds are produced.
2. Custom Molds: Molds shall be produced with ample layers of tooling resin, tooling gel-coat, glass fibers and/or flexible rubber by skilled mold makers with minimum of ten (10) years experience with architectural elements. Produced molds shall have rigidity and thickness to prevent distortion and deflection of molded architectural fiberglass.
MATERIALS CHARACTERISTICS
1. MOLDED EXTERIOR SURFACE:, NPG-ISO polyester gel coat, 18 to 22 mils thick. Gel coat shall be sandable grade for acceptance of finish paint. (Insert custom colored U-V inhibited gel coat when custom gel coat finish is specified.)
2. BARRIER COAT: Specifically formulated backup polyester surface veil 18-20 mils thick to prevent glass print through and ultimate Class A finish.
3. BACK UP LAMINATE:
  1. Resin: Polyester resin shall be fire retardant, and meet Class 1 flame spread rating of 25 or less and smoke density under 450 without the use of antimony trioxide as characterized by the ASTM E-84 tunnel test at typical 1/8″ glass mat laminate. General Purpose resin will not be permitted.
  2. Filler: Functional filler to be added to resin matrix to minimize shrinkage, add stiffness, control opacity, add fire retardance, improve surface finish, minimize crazing, and control dimensional stability from weather extremes.
  3. Fiberglass Reinforcement: Type “E” fiberglass, glass cloth, matt and/or random chopped glass fibers. Glass content approximately 20% to 30%.
  4. Laminate Thickness: Nominal laminate shall be minimum 3/16″ thickness. Additional core reinforcements and/or sandwich structure added as required for rigidity and structural integrity.
FABRICATION
1. Column cover halves shall be manufactured with sufficient butt joints to provide structural integrity and shall be manufactured to accommodate construction adhesive, and align with adjoining half section. (Insert custom engineered lap or reveal joint when specified.)
2. Column vertical joint shall be designed to accept polyester body filler for monolithic finish and field painting. (Insert that column vertical joint shall be caulked when custom reveal joint detail is specified.)
3. Column cover shaft half sections shall be manufactured as a single unit spanning entire height from base to top of capital.
4. Column base shall be manufactured as a separate unit for column shaft height adjustment.
