1.0 GENERAL
Doors shall be furnished by CORRIM Company in accordance with the specifications as
published in current literature. Installation shall be by the general contractor in strict
accordance with manufacturer's recommendations and instructions.
2.0 FRP FACE SHEETS (Fiberglass Reinforced Plastic)
2.1 FACE SHEETS
Standard face sheets shall be manufactured by others using a corrosion resistant
isophthalic polyester resin system with light stabilizing additives. The resin shall be
reinforced with fiberglass 40% by weight.
2.1.1 Face sheets shall be 0.070" to 0.125" in thickness. Standard being
0.120".
2.1.2 Where deemed necessary by either the client or the factory, one of the following
resin systems shall be substituted to meet the corrosive conditions: vinylester, high temp
vinylester, bisphenol polyester, halogenated polyester.
2.1.3 FINISH
- White color impregnated gel coat
- Gray color impregnated gel coat
- Special colors upon request
- 15 mils thick coverage
- Smooth seamless finish
2.2 ABS FACE SHEETS (OPTIONAL)
2.2.1 FACE SHEETS
Extruded ABS plastic sheet, fabricated by third parties, whose specifications, chemical
composition and structural characteristics are available upon request. ABS face sheets are
1/8" thick. Other thicknesses are available by request or arrangement.
2.2.2 FINISH
- All exterior surfaces shall be ABS textured material
- Bonded and sealed doors
- White color impregnated through the entire ABS material
thickness
- Special impregnated colors available upon request
- Special applied colors available using 2 part epoxy systems
upon request
2.2.3 SPECIALTY FACE SHEETS
Non-standard face sheets such as foamed PVC, lucite, plexiglass, wood veneers, etc. are
available upon request. Consult factory.
NOTE: Thermoplastic polymer products can react to extremes of cold and heat. They
can only be used for exposure to specific chemicals and U.V. conditions. Please be sure to
thoroughly research the operating conditions of the proposed doors or panels for proper
application.

3.0 INTERNAL CONSTRUCTION
3.1 CORE
3.1.1 STANDARD
Urethane core - A 1-1/2 inch thick rigid block of urethane shall be laminated to the
interior of face sheets. The "K" factor shall be 0.14 BTU in./hr./sq.ft. 2-4 lb.
density, or as required, shall be available.
3.2.2 OPTION
Balsa core - A core of end-grain balsa shall be laminated to the interior face sheets. The
balsa shall have a density 8.5-9.0 lbs./cu.ft. and be 1-1/2 inches thick. Compressive
strength, perpendicular to the door panel surface shall be 1,400 psi.
3.1.3 OPTION
Honeycomb core - B flute paper honeycomb shall be laminated to the interior face sheets.
(The paper is lightly coated with resin to enhance its strength and corrosion resistance.)
3.2 STILES AND RAILS
Stiles and rails shall be 1-1/2 inch square pultruded fiberglass tubes. A polyester-based
resin filled with 1/4" chopped glass strands and aerosil shall be used for
reinforcements and corner blocks, etc. The bottom rail shall allow 1-1/4 inches of height
alterability without loss of panel's integrity.
4.0 TRANSOMS
Transom panels shall be constructed using the same stile, rail, core material, and face
sheets as a standard door. Transoms shall be reinforced with non-swelling polymer blocks
where through bolts are used to attach to jambs.
5.0 HARDWARE PREPARATIONS
5.1 REINFORCEMENT BLOCKING
- Lockset … Non-swelling polymer blocking
- Surface Mounted Hardware … Non-swelling polymer
blocking
- Through Bolted Hardware … Non-swelling polymer blocking
5.2 MORTISE HARDWARE
- Full Mortise Hinges … Non-swelling polymer blocking
- Half Mortise Hinges … Non-swelling polymer blocking
- Mortise Locksets … To suit template provided
- Exit Devices … To suit template provided
All doors may be mortised and reinforced to allow field
application of hinges and locks, in accordance with approved hardware schedule and
templates supplied by a hardware contractor. Where surface mounted hardware is to be
applied, doors shall have reinforcing blocks only; all drilling and tapping shall be by
others unless specified at time order is placed. The hinges shall be attached by using
wood screws or through bolts. |
6.0 LITES AND LOUVERS
6.1 LITES
Lites may be factory installed and glazed prior to shipment. Single and double lites are
available. Plastic, aluminum or stainless steel may be selected for glazing stops or
moulding.
6.2 LOUVERS
Louvers shall be inserted, fiberglass type as provided by CORRIM Company and shall be
factory installed. Inverted "V" blades are standard. Screens may be supplied as
an option.
7.0 FACTORY INSTALLATION OF HARDWARE
Hardware and accessories may be factory installed as an optional service. |
8.0 FLAME SPREAD RATING
A fire retardant additive is added to the gel coat, face sheet resins, and the
polyurethane core to achieve a flame spread of 25 or less according to ASTM E-84 rating
for each of the component parts. It should be noted that this rating does not apply to the
door section as a composite. The standard construction doors are not fire rated as per
ASTM E-152.
9.0 RECOMMENDATIONS
CORRIM Company strongly recommends that only light colors be used for exterior doors,
since polymers, by their nature, expand in the heat and direct sunlight. Temporary bowing
may occur, especially in solid core doors. Honeycomb core will further reduce this
tendency. Doors will return to "normal" contour when sun is off them. |
