|---|---|---|
| Flamespread Index | ASTM E84 | 10 – Class A PASS |
| Smoke Development Index | ASTM E84 | 35 – Class A PASS |
Independent Testing
| PROPERTY | STANDARD/TEST | RESULT |
|---|---|---|
| Nominal Thickness | Calibrated Deadweight Micrometer | 0.023 inch (0.58mm) |
| Basis Weight | Electronic Weigh Scale | 5.16 oz/yd² (0.55 oz/ft²) 175g/m² |
| Drying Rate Analysis of Wet Plywood & OSB** | Water Loss (g) Over 100 hrs at 70ºF, 50% RH | 180 grams of water lost through WRAPSHIELD® membrane (double nearest competitor) |
| Water Resistance (UBC Flashing Requirements) |
ASTM E2112 (Appendix XI) |
24hrs PASS |
Tested in accordance with ICC-ES-AC 38 criteria to meet IBC and IRC requirements for Weather Resistive Barriers (ICC Certificate #ESR-1916).
ASTM E 96 - Method B (wet cup method) typically gives a more realistic result for permeance of highly permeable products than does the Method A (dry cup/desiccant method).
