I need some input regarding windows in a 2 year old house. I was called to inspect a problem with condensation on kitchen and bath windows. It is a very well built house, but even with somewhat high humidity, my feeling is that there should not be constant condensation running down on to the wood trim. At extreme cold temps, there is a frost buildup on the glass. I did a test by covering one pane of glass with an R-one Styrofoam and the condensation disappeared. Is there a way to test a window for proper R-value?
