MARVIN�� , Introduction and Product Performance ""°n°W° ° ` °°"' Buillaroundyou: Storm Plus: Code Requirements and Glazing � Regional Product Design Pressure Requirements International Residential Code/International Building Code: This set of building codes has fast been replacing the regional codes we have had available in the past. These codes represent the ' results of the many code governing agencies getting together to come up with a singular code language that meets all geographical locations within the building industry. The International Residential Code is written for typical residential construction and the International Building Code is more for ' Commercial use.Within these codes is language that places a building site geographically into different zones based on wind-speed and proximity to the ocean as listed here: Impact Glazing Zone 1 (IZ1): � 130mph and up to but not including 140 mph and within 1-mile of the mean high tide line and Hawaii. Design pressures in this zone will exceed 40psf for negative loads. The I-codes also specifically require wind-borne debris construction in this zone. Windows and doors must be designed to withstand an impact of a 4' long 2x4 stud shot out of a cannon at 40' per second (27mph) to simulate flying debris followed by a total of 9,000 high wind cycles to simulate a hurricane. � Impact Glazing Zone 2(IZ2): 140mph and up to but not including 150mph and more than 1-mile from the mean high tide line. Pressures in this zone approach 50psf for negative loads.Wind-borne debris requirements are identical to Zone 1. � Impact Glazing Zone 3(IZ3): For winds 150mph and up to 160mph, or 140mph and up to 160mph and within 1-mile of the mean high tide line. Design pressures in this zone can approach 65psf for negative loads. The I-codes specifically require wind-borne debris construction in this zone. � Windows and Doors must be designed to withstand an impact of an 8'long 2x4 stud shot from a cannon at 50'per second(34mph) to simulate flying debris followed by a 9,000 high wind cycles that simulate a hurricane. The make-up of IZ3 glass: � . Exterior piece of glass is annealed or tempered. . Interior piece of glass is laminated glass which is composed of a layer of PVB or SGP sandwiched between two pieces of annealed glass. Impact Glazing Zone 4(IZ4): � This is considered a high velocity wind zone and encompasses all areas with wind speeds in excess of 160mph. Design pressures in this zone often exceed 65psf and can approach 100psf. Wind-borne debris requirements include everything from Zone 3 as well as possible multiple hits per test unit and mullions. ' NOTE:Refer to wind speed map and ASTM E1996-14, subsection 6.2.2 for more information. , � , ' ' ' , ' CHECK MARVIN ONLINE DOCS FOR LATEST VERSION Printed On: Mar 22,2017,11:01 am ver2o�6.1 2016-02-29 INTRO/PRODUCTPERFORMANCE-16 19972255 , Marvin Architectural Detail Manual
