ASTM 2112 (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).

Third Party Testing Drying Rates 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.
