Last year, our contractor replaced our 60-year-old storm windows with Larson Performance 3-track storms. We encountered several problems: the windows not operating smoothly, rain leaking into several of them, condensation/frost forming on the storms upstairs, and, when the temperature dropped to single digits, condensation/frost forming on the inside of the primary (wooden) windows both upstairs and downstairs. We had none of these issues with our old storms. We're not sure of the rain leaking in is from poor window construction or improper installation. Adding more caulking (around screw holes, etc. where it should not be needed) MAY have solved that issue. The condensation on the storms seems to point to tighter storms (and leaky primary windows) than we had before. However, the condensation on the primary windows seems to point to colder temperatures between the primaries and storms, which would indicate leakier storm windows than we had previously. We tried covering our upstairs windows with plastic (inside), which greatly reduced the condensation on the storms on the south and west-facing windows, but had no effect on the east-facing windows.
Our options at this point seem to be 1) to keep our current frames, patching them with extra caulking to try to prevent rain leakage, and ordering replacement low-e glass in the hope that it reduces the condensation problems; 2) to replace the storms with Larson's L203E model (2-track Premium system)--however the air infiltration rates on these windows seems to be only slightly better than our current storms, despite the extra weather stripping, according to the Energy Star website (0.7 versus 0.8); or 3) to go with a different manufacturer, such as Harvey's 3-track storm, which claims a 0.05 air infiltration rate--a rate which seems to be based on testing done with no weep holes. (Harvey is not Energy Star rated/tested, so we don't have a true comparison.) We are at our wits end, and at a loss as to how to proceed. Advice?
