A Note About Permeability, Moisture and Mold

Vinyl wallcovering can act as a vapor barrier and consequently should NOT be installed on walls that are susceptible to excessive condensation or moisture infiltration. To reduce the risk of fungal growth, Len-Tex recommends that all wallcovering(s) be microvented* when installed in Humid and Fringe Zone 1 climates. (ref: ASHRAE Handbook of Fundamentals, Chapter 21, Figure 16).
