How to Make Insulated Window Coverings

Insulated window coverings or window quilts can be made for any window. These are particularly good for windows in rooms that are seldom used or even closed off in the winter. The window quilt improves the heat-loss resistance of the window as much as threefold and you should see that improvement reflected in your energy bill. Window quilts are easy to use to cover your windows; they can be put in place after dark in more commonly used rooms.

A diamond-shaped quilt pattern can be used for window quilts.
  1. Measure your window from inside your window casing. Add two inches to the length and width measurement.

  2. Cut the fabric, insulated liner fabric, quilt batting and liner fabric all to the same size. Place your fabric face-side down. Place your batting on top and add your insulated liner fabric. Place your lining fabric face-side up on top of the other layers. Pin all four layers together on all sides. Pin in the middle of the fabric to help when you quilt.

  3. Measure one inch from each corner. Draw a line between the marks and cut off the fabric at each corner. Place a quilt pattern over the pinned fabrics. With some patterns you can transfer the design using tailor's chalk through pin holes in the pattern. You can also do a simple diamond or square pattern.

  4. Sew the fabrics together. Sew 1/4 inch from all edges and sew your quilt pattern. The quilt pockets trap air and moisture coming from the window. Finish by positioning 1-inch bias tape so that it overlaps the raw edges. Sew the bias tape around the entire rectangle. Miter your corners and overlap and tuck your beginning and ending tape.

  5. Pin and sew the fuzzy side of hook-and-loop tape to the back edges of the window quilt. Sew at least two seams to hold the tape securely. Fit the quilt to the window and stick the adhesive-backed hook portions of the tape to the inside of the window casing. The quilt should be two inches larger to allow the fabric to fit to the hook-and-loop tape.
