Vinyl storm windows are available in both double track and triple track combination storm windows and screen.  The vinyl storm window is affixed directly to the existing window frame.  Ventilation is made possible by sliding the screen.

How to install vinyl storm windows

Step 1–The perfect fit

Measure all of windows that will have vinyl storm windows and be sure that all measurements are accurate before ordering.

If the vinyl storm windows do not fit properly they will not have a tight seal or operate correctly.

Step 2–What you will need for installation

• Exterior caulk
• Caulk gun
• Drill
• Sheet metal screws

Step 3–Getting started

Drill holes around the frame of the vinyl storm windows every 12 inches if needed.  Most vinyl storm windows come with pre-drilled screw holes.

Step 4–Adding adhesive

Apply caulk to the frame of the vinyl storm window.  Then add caulk to the outer edges of the house window frame.  Take care to distribute the caulk evenly so the vinyl storm window will have a good seal.

Step 5–Installation

Gently press the prepared vinyl storm window into the opening of the house window.  Make sure the vinyl storm window is centered and level.  Leave a slight gap at the top for expansion due to temperature changes and ensure that the bottom is touching the windowsill.

Step 6–Operation

Now that the vinyl storm window is in place try the storm windows and screen for proper smooth use.

The vinyl window screen frame many need adjusting if there is a problem with sliding the storm windows and screen.

Step 7–Completing the installation

Start at the top of the vinyl storm window to drill in screws and move around the window until all of the holes are filled.  After, fastening the vinyl storm window caulk the bottom edge. 

Use caution not to caulk holes at the bottom of the vinyl storm window.  These holes release moisture from the vinyl storm window. 

If the window does not have drainage holes along the bottom edge leave a couple of small spaces open. 

To finish the project secure the vinyl storm window extender to the main windowsill.  Accomplish this by putting the screws in the window sill so that the screw heads hold the extender in place.
