I live in Austin and thieves broke through french doors at my home. I thought they were secure! I bought a Zeus hurricane sliding glass door to keep robbers out. The Zeus online system is great, I even ordered 6 hurricane windows for the front of my house facing a freeway and train track to reduce noise. Ordering was a breeze, got an installer no problem. Zeus beat local Austin window/door companies by over 55%. No traffic/train noise and even in direct sun the Zeus inside panes stay cool! Really happy here
If you are not good on a ladder or even a stepladder, don’t attempt this. You really need 2 people for this, one to measure and the other to write those measurements down. See the diagram below and there is one video. This is similar to measuring for window treatments where you take a top, middle and bottom measurement for the width and the same for the height. Take the smallest of the 3 measurements of the width and the smallest of the height and subtract 1/4 inch from the narrowest width and 1/4 inch from the shortest height measurement. Enter this on your diagram. The measurement is taken from where the existing window frame meets the exterior of the home.
