How to use the table

1. In the table below look for maximum wind uplift values that equal or exceed the requirements determined through the RCI calculator;
   (NOTE: while the reports show two different values for tested maximum assembly strength, the RPM tables display only the values adjusted for the required safety factor of 1.5)
2. Open the report for the tested assembly that fits with the design parameters you have chosen and calculated, and examine the report. It will break down the assembly by its components. Ensure all the key components (Secondary materials, such as deck overlay, insulation and insulation overlay) are accepted by the RoofStar Guarantee Program (note that fasteners and adhesives currently are not listed in this Manual - use the materials specified in the wind test report, or consult the membrane manufacturer);
3. In cases where a tested Secondary material is not accepted by the RoofStar Guarantee Program, look for alternates which often are published in the each report. In the absence of published alternates, consult the listed manufacturer for alternates that are accepted by the RoofStar Guarantee Program, and obtain the manufacturer's written approval.
