Installing an interior storm window gives you great insulation and protection from the elements, without ruining the look of your home’s façade. Depending on the model of storm window that you’re interested in, buying one from the hardware store can cost upwards of $100; and if you have a lot of windows in your home that need protecting, that can easily become exorbitantly expensive! Fortunately, it’s surprisingly easy and cheap to make your own hinged interior storm window; in fact, if you follow the instructions laid out in this easy guide, you won’t spend any more than $25 max per storm window! Keep reading to find out how.

Step 1 – Measure the Window Frame

First, measure the size of the window that you will be fitting your hinged interior storm window into. Take note of the measurements.

Step 2 – Cut the Wood to Size

Use your saw to trim your 1x2 pieces of lumber to the appropriate frame size. Remember to exercise safety precautions whenever you use your saw! Remember to make the frame slightly smaller than the window jamb so that you won’t have any problems inserting it; but not so much smaller that air will be able to get in around the frame.

Step 3 – Make the Frame

Take the four pieces of wood and hammer them together to make the frame. Use stain and varnish as desired to create a look that is harmonious with the area of the home that you’ll install the frame in. If the frame is large, you may want to add a cross-piece.

Now comes the part that will really save you a lot of money. Instead of putting glass inside the frame to make the storm window, you can just use insulating window film. This type of window film was originally intended to be applied to your main window in the winter, then removed in the spring, in order to give you extra insulation. Instead of having to go through that process every year, though, you can simply stretch the window film over the frame that you made as a replacement for the glass. Staple it into place on the frame.

Step 4 – Add the Hinge

Finally, use your drill to install the hinge onto the window frame, in the area that you would like to have it attached to the window jamb (usually on the top). Then, attach the frame via the hinge to the window jamb, and voila; you have a quick and easy interior storm window that can easily be lifted in and out of place!
