is a computer-modeling service provided by Grace to help design
professionals and building owners make educated decisions about exterior
wall designs. The Perm-A-View analysis is a dynamic simulation of heat
and moisture transport through a multi-layer exterior wall exposed to
natural weather. The Perm-A-View output is a complete report quantifying
the potential for organic (mold) growth on moisture-sensitive wall
components and the potential for corrosion on corrosive materials. The
report also identifies how much energy would be required to maintain the
specified interior temperature over a one-year period.
Perm-A-View analysis uses historical weather data from US cities.
To inquire about conducting a Perm-A-View analysis, please contact your local Grace Air Barrier representative.
