But not every advanced building solution or product makes sense for everyone. For many, repair work is a desirable alternative to replacement.
In a collaborative effort, the Vermont Energy Investment Corporation, the University of Vermont’s Department of Civil and Environmental Engineering, and the U.S. Army Cold Regions Research and Engineering Laboratory set out to test the value in wood-window repair. In their 1996 paper, “Testing the Energy Performance of Wood Windows in Cold Climates,” they assessed the performance gains accrued through various wood-window upgrades, including the…
