once in, they don’t pop off like magnets do with pressure swings
Yeah, I had the magnetic ones and it was like playing whack-a-mole every time the wind shifted. Compression-fit worked better for me too, but man, getting them to seal on my 80s windows was a pain. Anyone tried those fancy exterior storm panels with pressure relief? Or is that just overkill at this altitude?
I actually gave those exterior storm panels with pressure relief a shot last winter. Honestly, they’re not as overkill as I thought—especially when the wind turns your living room into a wind tunnel. The install was a bit of a pain (lots of fiddling to get them seated right), but they did seem to help with the pressure swings and random drafts. Not super cheap, though, and you still get some condensation if your windows are really old like mine. If your altitude is above 7,000 ft, I’d say it’s worth considering... but maybe not for every single window.
“The install was a bit of a pain (lots of fiddling to get them seated right), but they did seem to help with the pressure swings and random drafts.”
I can relate to the installation hassle. I tried a single pressure-relief panel on one upstairs window this season—took me nearly an hour just to get the fit where it wasn’t rattling or leaving gaps. The pressure difference at 7,500 ft is no joke during wind storms, though, so I did notice fewer whistling sounds and less movement in the curtains. That said, I’m still skeptical about the condensation issue. My windows are original to the house (1979 build), so even with the panel, I get a little fogging at the corners when it drops below 10°F. Not sure if that’s a panel flaw or just old glass.
Cost-wise, yeah, it’s not cheap. For my budget, outfitting every window seems excessive, especially for rooms we barely use. I’d say they’re most useful on big west-facing windows that catch the brunt of the wind. Anyone else notice that drafty feeling drop off after installing these? Or am I just getting used to living in a wind tunnel...
“even with the panel, I get a little fogging at the corners when it drops below 10°F. Not sure if that’s a panel flaw or just old glass.”
That corner fogging is super common with older windows, especially single-pane or aluminum frames from the 70s. The panels help with drafts and pressure swings, but condensation’s usually more about the window’s insulation value and how much moisture’s in the air inside. I’ve seen some folks try using a dehumidifier in those rooms—sometimes helps, sometimes not. Did you notice any difference in room temp after installing the panel, or just less movement in the curtains?
