Windows And Leakage

摘要

In April's Building Sciences column by Joseph W. Lstibu-rek, Ph.D., P.Eng., Fellow ASHRAE, I think the author missed the most important portion of the cup concept in Figure 1. In residential construction with double-hung windows and with the ever-present aftermarket combination of storm window/fly screen units, it would be important to use a fourth cup example.rnFor this example, with the outside face baffle moved down to the bottom of the cup, and with an open space between the top of the cup and baffle, drill a small drain hole at the junction of the cup lip and the baffle plate.
