Vapor Barrier Systems

Vapor Barriers are typcally used in climates that are either predominantly hot or cold year round.  This is because these climates have a consistent vapor drive inside to outside or outside to inside) that does not shift with the change in seasons. (See Sto Tech Hotline #0806 BSc for more information about proper use of vapor barriers)

StoGuard with VaporSeal is a fluid applied vapor barrier that is used in place of housewrap or building wrap to provide superior protection against moisture intrusion and air leakage, saving energy and helping improve indoor air quality. In addition, it can be left uncovered for extended time during the construction process, simplifying scheduling and protecting exposed sheathing from moisture, mold and mildew.
