PATH - A Public Private Partnership for Advancing Housing Technology
Field Evaluation: Williams Building Diagnostics, Inc.
Final Report (PDF) April 2006
There were two field tests of existing buildings in which substantial moisture damage had been repaired-a two-story residential house and a small-scale commercial building. Both buildings were repaired using pan flashing integrated with weather resistant barriers. To augment the field tests, laboratory mockups were constructed to test weather-resistant barriers and pan flashing systems:
For best results, builders should slope the sill pans, or use products with an integral slope, to ensure that water does not reach unprotected wood, and that it also drains away to the exterior of the wall.
Monitoring of the two field sites is ongoing.
