How to Make Storm Windows for a Screened Porch

Screened porches can provide a comfortable setting during the warm months, though cold drafts may become an issue once temperatures begin to drop.
Adding storm windows to a screened porch can help keep cold air away from the main doors and walls of the home. Making removable storm windows involves constructing the frames and adding a plastic covering.

Step 1

Measure the length and width of the existing porch windows. It’s all right if the newly made storm windows are a bit smaller than the actual window sizes as long they’re sized proportionally.

Step 2

Construct the storm window frames using 1-by-2-inch pieces of pine or oak, or purchase screen framing pieces at any local hardware store. Screen framing pieces snap together at the corners. Otherwise, a 1-by-2-inch piece will require mitering at the ends so the pieces can be glued and nailed together.

Step 3

Tape plastic shrink wrap to the newly constructed frame using two-sided bonding tape. The thicker the plastic wrap, the better. Cut off any excess.

Step 4

Create a seal or gasket material using long strips of polyethylene plastic. Fold the strips over to create a layering effect and place them along the back side of the frame. Staple the strips in place.

Step 5

Place the newly made storm window onto the frame of the existing window. Brace the storm window in place using swing cleats. Use a drill and wood screws to attach a cleat at each corner of the window frame so that a tight fit exists between the storm window and the frame.

Things You Will Need

  • Measuring tape
  • 1-by-2-inch wood pieces, or screen framing kit
  • Glue
  • Plastic shrink wrap
  • Bonding tape, double-sided
  • Scissors
  • Polyethylene plastic strips
  • Staples and staple gun
  • Wood cleat, 1 to 2 inches
  • Wood nails, 1 1/2 to 2 inches
  • Drill
  • Wood screws

Tip

  • Place labels on the back and top sides of the frames. This allows for easy installation when it comes time to put them back up for the winter.

Warning

  • When you first position the storm window, push them in slowly so any trapped air can escape from in between the main window and the storm window.
