FIRE TESTING
| PROPERTY | STANDARD/TEST | RESULT |
|---|---|---|
| Flamespread Index | ASTM E-84 | 5 – Class A PASS |
| Smoke Development Index | ASTM E-84 | 70 – 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 |
280 grams of water vapor lost through WallShield membrane (four times nearest competitor) |
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).

Third Party Testing Drying Rate Comparisons
VaproShield breathable membranes are unsurpassed in their ability to dry wet sheathing.
Third-party testing results clearly indicate the superior drying capability of both WallShield and WrapShield.
Drying is essential in preventing the damaging effects of mold, mildew and rot resulting in repair costs, poor indoor air quality and strain on HVAC systems.
