  • AIA statement that Peetz is an approved provider (don’t spend time reading)
  • You will have a basic understanding of how a hurricane effects a building structure You will have a basic understanding on the wind-borne debris code requirements for impact resistant windows and doors You will learn about product approvals and design options for mahogany impact resistant windows and doors You will learn about the various design criteria and how to specify mahogany impact resistant windows and doors
  • Wind-borne debris regions are defined as areas along the Atlantic and Gulf Coasts where the design wind speed is 120 mph or above, or within one mile of the coastal mean high water line where the wind speed is 110 mph or above. In these regions, the standard requires the designer, either an engineer or an architect, to assume that the windows and doors will be broken by wind-borne debris unless those openings are protected against such items. Protection can be achieved through the use of hurricane shutters or impact-resistant glass The wind-borne debris region extends about five miles inland in most cases and considerably further in others. But, in the Panhandle region (sections of northern Florida from the Walkula/Franklin County line to the western edge of Escambia County), the legislature designated the wind-borne region as the land within one-mile of the Gulf Coast. ASCE Methodology reference by Florida Building Code Uses a series of calculations to include wind speed, size, shape and location of building. Resulting design wind load is expressed in Pounds per Square Foot (PSF)
  • Here is an outline of the missile levels specified in the ASTM E 1996 document along with their description and intended impact speed – we have also listed some typical areas of use for these missiles. Note: Level A is equivalent to small missile for the H igh V elocity W ind Z one (Dade County), and Level D is equivalent to the large missile for the HVWZ. Missile A is most common for small missile requirements, 30’ above ground level Missile D is most common for large missile requirements up to 30’
  • Designed to simulate both positive and negative pressures exerted by a hurricane on structures Plays a role in determining the maximum design pressure for which a product is approved Consists of 9,000 total pressure cycles that range from 1 – 3 seconds in duration Test is conducted on test assembly after it has undergone impact testing

    39. 41. <ul><li>Water infiltration is expected during major wind or storm events with the presence of water. </li></ul><ul><li>NOA’s will include the testing data that confirms a glazing system’s water resistance performance in the laboratory (ASTM E331 and ASTM E547) </li></ul>
    40. 42. <ul><li>Water Infiltration Testing requirements for glazing systems are NOT specifically stated in Building codes , therefore water resistance may not be required and where designated may vary (+ / -) from the NOA or manufacturer’s lab test DP. </li></ul><ul><li>ASTM E1105 Field Water Infiltration Testing is the equivalent to ASTM E 331 and ASTM E 547 lab testing and is typically performed from 15% to 20% of maximum positive design pressure. This usually results in 20 PSF or less – water resistance. A minimal hurricane CAT 1. </li></ul><ul><li>A Category 1 Hurricane with minimal winds of 77 miles per hour requires that the glazing system resist up to 15lbs/ft of water, or a head of approx. 3” of gathered water at the sill of the assembly. </li></ul>
    41. 43. <ul><li>Development and Design; Water resistance should be a major priority in the selection process of selecting a glazing system in HVHZ areas. </li></ul><ul><li>Specifications; must state that the lab test design pressures are duplicated in the field (on the project). Part 3: Execution. </li></ul><ul><li>AAMA guidelines are not as stringent for glazing systems tested in the field. </li></ul><ul><li>REMEMBER ; The higher design performance requirements for the resistance for water infiltration…………the better! </li></ul>
