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.
