ESR-2528 Page 3 of 19 <br />4.6.4 2012 IRC: For basic wind speeds (3 second gust) of 100 mph (161 km/h) or less and mean roof heights <br />of 40 feet (12 192 mm) or less, tiles must be installed in accordance with the prescriptive parameters of Section <br />R905.3.7 of the IRC. For applications beyond these prescriptive parameters, the tiles and fastening systems <br />must be designed in accordance with Appendix A of this report. <br />4.6.5 2009 IBC, 2009 IRC, 2006 IBC and 2006 IRC: For maximum basic wind speed of 100 mph (209 km/h) <br />or less and mean roof heights of 60 feet (18.3 m) for the IBC and mean roof heights of 40 ft (12.2m) for the <br />IRC, tiles must be installed in accordance with the perspective parameters of IBC Table 1507.3.7 or IRC <br />Section R905.3.7. For applications beyond these prescriptive parameters, the tiles and the fastening systems <br />must be designed to withstand the aerodynamic wind uplift moment in accordance with the section on Design <br />Considerations for High Wind Applications in Appendix B of the TRI/WSRCA installation manual. The generic <br />required aerodynamic uplift moment, determined in accordance with Tables 5A through 6D of the TRI/WSRCA <br />installation manual, must be multiplied by the tile factor ratio of the tile in Table 1 to obtain the required <br />aerodynamic uplift moment for the specific roof tile being installed. The allowable aerodynamic uplift moment <br />for the roof tile fastening system selected from Table 7A of the TRI/WSRCA installation manual, must be equal <br />to or greater than the required aerodynamic uplift moment for the specific roof tile being installed. See Appendix <br />B of the TRI/WSRCA installation manual, dated March 2010 for additional details. <br />4.7 Adhesively Attached Systems: <br />Flat and Venetian Flat and Venetian concrete roof tiles may be installed with a roof tile adhesive that is listed <br />in a current ICC-ES evaluation report for use in concrete roof tile applications. Installation of tiles using the tile <br />adhesive must be in accordance with the adhesive manufacturer’s ICC-ES evaluation report. <br />4.8 Reroofing Applications: <br />The tiles may be installed over existing roofs, provided the requirements of 2021 IBC Section 1512 [2018 and <br />2015 IBC Section 1511 (2012, 2009 and 2006 IBC Section 1510)] or 2021, 2018 and 2015 IRC Section R908 <br />(2012, 2009 and 2006 IRC Section R907), as applicable, are met. The roof classification is as noted in Section <br />4.5. <br />5.0 CONDITIONS OF USE: <br />The Flat and Venetian concrete roof tiles described in this report comply with, or are suitable alternatives to what <br />is specified in, those codes listed in Section 1.0 of this report, subject to the following conditions: <br />5.1 The tiles must be manufactured, identified and installed in accordance with this report, the applicable code, <br />and the TRI/WSRCA installation manual, dated March 2010. The instructions within this report govern if <br />there are any conflicts between the installation manual and this report. <br />5.2 The roof sheathing and roof framing system must be designed for the appropriate loads determined in <br />accordance with the applicable code, subject to the approval of the code official. <br />5.3 The roof tiles are manufactured under a quality control program with inspections by ICC-ES. <br />6.0 EVIDENCE SUBMITTED <br />Data in accordance with the ICC-ES Acceptance Criteria for Clay and Concrete Roof Tiles (AC180), dated <br />February 2012 (editorially revised July 2022). <br />7.0 IDENTIFICATION <br />7.1 The ICC-ES mark of conformity, electronic labeling, or the evaluation report number (ICC-ES ESR-2528) <br />along with the name, registered trademark, or registered logo of the report holder (Stoneworth Building <br />Products) must be included in the product label. <br />7.2 In addition, each Venetian tile is embossed with the words “Vortex Hydra Italy” or “CFL” or “ALLYNDEB <br />TILE CFL.” Additionally, each Flat tile is identified with the embossments “Sandstone” and “Vortex Hydra <br />Italy.” Each shipping pallet is identified with the Stoneworth Building Products address; the manufacturing <br />location; the product name (Flat or Venetian) and the installed weight. <br />7.3 The report holder’s contact information is the following: <br />SANDSTONE INC., dba STONEWORTH BUILDING PRODUCTS <br />4025 BONNER INDUSTRIAL DRIVE <br />SHAWNEE, KANSAS 66226 <br />(913) 422-0794 <br />www.stoneworthcompany.com <br />302 E Santa Clara Ave <br />9/25/2024
