SUGGESTED SPECIFICATIONS:
GENERAL: Furnish and install where indicated on the drawings C/S 4 (101.6 mm) STORM
RESISTANT FIXED VERTICAL LOUVER MODEL RS-4600 as manufactured by
Construction Specialties, Inc., Cranford, New Jersey. Complete details shall be submitted to the
architect for approval prior to fabrication. The supplier must be a member of AMCA or BSRIA.
MATERIAL: Frames and blades to be fabricated from 6063-T6 aluminum alloy. Blades to be
minimum 0.060 (1.52 mm) thick extrusions and frames to be a minimum 0.080 (2.03 mm)
thick. Louver to be mechanically fastened using stainless steel or aluminum fasteners. Louvers to
be supplied with 4 (101.6 mm) high by full depth sill flashing formed from minimum 0.050
(1.27 mm) thick aluminum. Sill flashing to have welded side panels. Louvers and sill flashing to
be installed in accordance with the manufacturer’s recommended procedures to ensure complete
water integrity performance of louver system. Louvers to be furnished with ½ (12.7 mm) mesh
screen secured within a 12 B & S gauge extruded aluminum frame.
STRUCTURAL DESIGN: Structural supports shall be designed and furnished by the louver
manufacturer to carry a wind load of not less than ________psf. (kPa). (Note: If this paragraph is
omitted or if the design wind load is not specified, the louvers will be manufactured in self
supporting units up to a maximum of 5 (1524 mm) wide by 8 (2438 mm) high. Any additional
structural supports required to adequately secure these units within the opening shall be the
responsibility of others.

FINISH: All louvers shall be finished with C/S Powder Coat, a coating to be 1.5 to 3 mil. thick
full strength 100% resin Fluoropolymer coating. Finish to allow zero VOCs to be emitted into
facility of application. Finish to adhere to a 4H Hardness rating. All finishing procedures shall be
one continuous operation in the plant of the manufacturer. The coating shall meet or exceed all
requirements of AAMA specification 2605 “Voluntary Specification for High Performance
Organic Coatings on Architectural extrusions and Panels.” The louver manufacturer shall supply
an industry standard 20-year limited warranty against failure or excessive fading of the
Fluoropolymer Powder Coat finish. This limited warranty shall begin on the date of material
shipment.

WIND DRIVEN RAIN PERFORMANCE:
The louver test was based on a 39.370 (1.00 m) x 39.370 (1.00 m) core area unit tested at a
rainfall rate of 3 per hour (75 mm/hr) and with a wind directed to the face of the louver at a
velocity 29.1 mph (13 m/s). The test data shall show the water penetration effectiveness rating at
each corresponding ventilation rate.
