Perm-A-View™ 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.
