Products / Grip-Rite ShingleLayment LWE-GRE

ShingleLayment LWE-GRE is the lightweight version of Grip-Rite's ShingleLayment-15 Pro: a woven 8x8 scrim polypropylene with a non-skid polypropylene coating and texture on both faces, sold with an installer print (LWE) or shingle print (GRE). The product page and family sell sheet give 4 by 250 foot, 10-square rolls weighing 19 lb, 85 GSM, 6.5 mil, a heat-diffusing gray facer and UV resistance up to 180 days, and the page claims it is nearly five times lighter than #30 felt with 4.6 times the coverage. The ShingleLayment family sheet lists ICC ESR-2945 under AC188 and ASTM D8257, ASTM D226, ASTM D4869 Type IV, CAN CSA A123.3-05, Miami-Dade NOA 24-0610.01 and Florida FPA 12510, and says the line is "Class A Fire Tested" without naming the test. The ShingleLayment warranty covers it for 25 years on a single-family residence and 20 years on other structures, though its remedy clause refers to a twenty- or fifteen-year term.
