How to Seal Old Drafty Windows

By Hklbrries

Q. We have older aluminum-framed sliding windows that are incredibly drafty. Is there some way to seal these things? We can’t afford new windows now.

-

A. There are a couple of relatively inexpensive treatments that should improve the performance of these windows in cold weather. The same treatments can be used on wood-framed windows.

-

Keep in mind that either of these treatments will temporarily prevent you from opening the windows – at least until the sealing material is removed.

-

If the problem is drafts around the perimeter of the sliding panels, you can seal them with a removable weather-stripping caulk such as DAP’s Seal’n Peel. This clear caulk can be applied to the inside of the window frames and can be peeled off when the weather improves.

-

DAP says the caulk won’t harm painted surfaces. Look for it in the weather-stripping department of home centers or visit www.dap.com for more information.

-

A second treatment, which can improve the overall energy-efficiency of the windows, is to cover the insides with shrink-type plastic film. The plastic is generally sold in kits with enough material to cover several windows.

-

Window-sized sheets are taped to the interior frames of the windows; when heat is applied with a hair dryer or heat gun, the plastic shrinks to a wrinkle-free cover that serves the same purpose as a storm window.

-

Despite their low cost (a kit usually costs less than $20), these covers are highly effective at stopping drafts and heat loss. They can be removed in good weather.

-

Again, check the weather-stripping department of home centers or buy online by using a search engine and the words Inside Plastic Storm Windows.
