How to measure

<p>Simply measure the window between interior trim on sides = width, measure your window between the top and bottom trim. Check attached picture with instructions <a href="https://ubrothersconstruction.com/storage/MY%20Files%20For%20Remote%20acces/vAf5mylP7QezbzbaVURbG4dPJQgyeIOSHK0Xhvu8.png">HERE.</a></p>

Please choose your insect screen type

What to choose?

In most cases, you will open only one sash at the time. So half screen is an "ok" choice. If you use window AC units you must choose half screen.

Please choose your installation type

What is the difference?

<p>"Replacement window" installation involves replacing only the window&rsquo;s existing sash and leaving the window frame intact. New window will be installed into the existing window frame. This economical option does not disturb the existing exterior and interior trims.</p> <p>"New construction" installation involves completely removing the existing window and replacing it with a new one. With this option, you can easily change the function, performance and appearance of your entire window&rsquo;s style. By doing this kind of installation you can easily repair rotten wood, improve insulation around windows and get more glass area.
