Let us take a moment to examine the anatomy of a storm window. We’re talking about exterior storm windows – the type that mount on the outside of your house to serve as an extra layer of protection against the elements. Storm windows generally consist of the glass and the frame. Storm window frames can be made of any number of materials. Older storm window frames are wood; more modern exterior storm window frames are aluminum or vinyl.
There are two ways a storm window can fail. The first is fairly obvious: when the glass breaks, your storm window isn’t going to work anymore, and it’s time to get new storm windows installed. The second problem may be less apparent to the naked eye. Storm window frame failure can happen when extreme winds or weather force a storm window frame out of shape; ice buildup, material failure, and even attempted criminal entry can all compromise your storm window frame integrity.
When your storm window frame fails, it no longer keeps cold air and moisture out. This means rain, snow, and cold can sneak behind the storm window and your existing interior windows; if your interior windows are not robust, the cold and moisture may even make it into the interior of your home. To watch for storm window frame failure, consider the comfort of the room in question: if it was previously cozy, and is now full of chilly drafts, the storm window may have failed. Fogged or heavily condensed windows are another sign.
What should you do if your storm window frame has failed? If you have recently had storm windows installed in the South Shore area, they may still be under warranty. You’ll want to talk to your replacement window company for details. If your storm windows are older – particularly if they’re wooden frame storm windows, it may be time for storm window replacement.
