This is in accordance with the large missile test requirements of ASTM E1996 (TAS 201) if within the Wind-Borne Debris Region, which is defined as one of these three: mph basic wind speed mph basic wind speed within one mile of the coast 3. All of Hawaii ASCE-7, which is adopted by the IBC, defines wind speeds (mph) and provides methods for determining wind loads (psf). HAWAII = 90 mph = 100 mph = 110 mph = 120 mph = 130 mph = 140 mph = 150 mph

7 Protocol Descriptions Applicable For Wind-Borne Debris Region High-Velocity Hurricane Zone TAS-201: Large Missile Impact Test (ASTM E1996) The Florida Building Code requires that products installed in the Wind-Borne Debris Zone or High-Velocity Hurricane Zone must meet or exceed impact test criteria established under TAS-201. Products may be exempt if utilized in open structures or installed more than 30 feet (9 m) above grade. This test procedure measures a product s capacity to withstand impact from wind-borne debris under hurricane-force wind velocities. Test Fan Size: Maximum size selected by manufacturer for certification. Test Missile: 7 foot ( 2.1 m) to 9 foot (2.75 m) long Southern pine 2 x 4; 9.0 to 9.5 pounds. Distance from Front of Canon to Face of Fan: 9 feet (2.75 m). Impact Velocity: 50 feet per second (15.25 m/s). Procedure: Three specimens are tested. One impact is delivered at the center of each specimen and one impact is delivered at top and bottom of each specimen, for a total of three impacts. Pass/Fail: Failure occurs if a change in the condition of the specimen results such as cracking, fastener loosening, local yielding or if penetration of the projectile occurs beyond the inside plane of the fan. TAS-202: Uniform Static Air Pressure Test (ASTM E330) The Florida Building Code requires that all products utilized in structures located throughout the state meet or exceed the structural test criteria established under TAS-202. This test procedure measures a product s ability to withstand maximum static pressure differentials typical to hurricane events.

11 Roof Curbs Roof Curbs Greenheck hurricane and high wind fans are designed for easy mounting to a variety of roof curbs. For your convenience Greenheck offers the industry s largest selection of tested and approved High Wind and Hurricane roof curbs. Greenheck Models GPF, GPFP, GPFV, SD and SDP curbs offer fully configurable sizes for both flat and pitched roofs. Selectable in sizes up to 80 x 80 inches (2032 x 2032 mm) and heights ranging from 8 inches (203 mm) to 24 inches (610 mm) tall. For applications where factory supplied curbs are not an option, the Greenheck high wind and hurricane fans can be used in conjunction with any previously installed or customer supplied curbs as long as they meet a series of minimum requirements. Considerations like no wood nailers, minimum material gauges and specific material types may allow field supplied curbs to be acceptable. GPF The GPF is a straight sided curb constructed of heavy gauge galvanized steel with a 5-inch (127 mm) flashing flange. It is designed specifically for use in high wind applications on flat roofs. Roofing material can be wrapped up over the top of the curb or can be directly flashed to the side of the curb for a complete tested and certified installation. GPFP The GPFP is similar in construction to the GPF. It is constructed of heavy gauge galvanized steel and can be configured to match the pitch of the roof ensuring that any fan mounted to the GPFP is going to sit level and operate properly. The 5-inch (127 mm) flashing flange can be used to secure the curb to the roof of metal (steel), concrete or wood frame building and easily flashed over to ensure weather tightness. GPFV The GPFV vented roof curb is typically used for kitchen applications; the vents allow hot air and gases to escape between the ductwork and roof curb. This curb is designed for use with Greenheck fan models CUBE and CUE to provide the required 40 inch (1016 mm) minimum discharge height above the roof line per NFPA 96. This curb is to be used on non-insulated flat roof decks. Model GPFV is mounted directly to the roof deck structure, roofed to the vertical surface and sealed to the 5 inch flashing flange. It is available in nine different sizes. Special Purpose Roof Curbs SD The SD curb is Greenheck s highest strength curb constructed with a minimum 12 gauge high strength steel. A 2-inch (51 mm) reinforcement angle is provided on taller sizes. The fan curb is coated as standard with our Permatector high performance coating (other coatings available). The SD curb is available in heights up to 24 inches (610 mm) and is ideal for larger and heavier units or areas where the wind speed are the most extreme. SDP The SDP curb is similar in construction to the SD. Minimum 12 gauge steel with the 2-inch (51 mm) reinforcements and a 4-inch (102 mm) flashing flange make it strong and easy to install. The curb can be configured to match the pitch of a sloped roof so that the fans sit level on the curb. This curb is ideal for supporting heavier, larger equipment or for use in extreme wind conditions. 11
