Air permeance is defined as the rate of airflow through a unit area of material under a given pressure difference. The performance of the air barrier materials is measured in L/(s•m2) (cfm/sf) of air leakage. Air barrier systems require complete continuity as any gap, hole, or crack allows for air transfer.
Building over three stories? Commercial-grade TYPAR MetroWrap goes above and beyond in delivering superior weather barrier performance for multifamily dwellings, light commercial projects, and large commercial structures. Incredible tear strength keeps it holding tight during construction. Plus, it stands up longer to ultraviolet (UV) degradation than the rcs data leading competition, which helps take the pressures off construction delays and changing timelines.
Some not-to-miss facts are:
no UV degradation for up to 12 months;
tear strength five times greater than the competition;
superior air and water holdout reduces energy costs;
protects indoor air quality (IAQ);
resists damaging surfactants and cleaning techniques; and
offers lifetime limited warranty coverage when installed as part of our complete system.*
