Upon contact with flood water, the flood vents automatically open and allow flood water to enter and exit enclosed areas. The vents are constructed of general purpose ABS SP-9010 plastrc. The Crawl Space Flood Vent Model #CSBA816 has a faux louver with either a solid plastic plate or wire mesh attached to the back of the louver. The louver rs dislodged from the vent upon contact wth flood waters. See Ftgure 1 for an rllustration of the flood vent Model #CSBAB16. The Flood Vent lnsulated Kit Model #ICCtNStJLATED is constructed of general purpose ABS Sp-9010 plastic. The vent frame opening is fllled with a 2-inch thick (51 mm) extruded polystyrene StyrofoamrM Brand Scoreboard Foam lnsulation Board (ESR-2142). The insulation board is dislodged from the vent upon contact with flood waters. allowing flood waters to enter and extt enclosed areas. See Figure 2 for an illustration of the Flood Vent lnsulated Kit Model #ICCINSULATED. The Crawl Space Stacked Model #ICCSTACKED2 contains two vertically arranged Crawl Space Flood Vents (Model #CSBA816) in one assembly. The Crawl Space Stacked Model#ICCSTACKED4 contarns four Crawl Space Flood Vents (Model #CSBA816) in one assembly, with two sets of side by side flood vents vertically arranged 3.2 EngineeredOpening: The Crawl Space Door Systems static flood vents comply with the design principle noted in Section 2.7.2.2 of ASCE/SEI 24 Iot a rcIe of rise and fall of 5 Feet per hour (0.423 mm/s) ln order to comply with the engineered opening requrrement of ASCE/SEI 24-14, the flood vents must be installed in accordance with Section 4.0 of thrs report. 3.3 Ventilation: The Crawl Space Flood Vent Model #CSBA816 and CrawlSpace Stacked l\rodels #ICCSTACKED2 and #ICCSTACKED4 are available covered with metal wire mesh with 0108 rnch by 0.108 rnch 12.74 mm by 2.74 mm) openings. The mesh is covered by a faux louver with 1 1/16 inch (17.5 mm) verttcal clearance between each blade. The Crawl Space Flood Vent Model #CSBA816 provides 11 square inches (7097 mm?) of net free area to supply natural ventilation when equipped with wire mesh. The Crawl Space Stacked Models #ICCSTACKED2 and #ICCSTACKED4 supply 22 square rnches ('14,'194 mmr) and 44 square inches (28 388 mm'), respectively. of net free area to supply natural ventilation when equipped with wire mesh.
