Your porch, your way — open and airy or sealed from the elements. Xtend Porch Windows let you enjoy the feeling of being outside while keeping rain, wind, dust, and snow where they belong. Open them wide on a beautiful day. Close them when the weather turns. It's that simple.
The ONLY factory direct porch windows solution.
Xtend Porch Windows
Our Xtend Porch Windows combine the open feeling of a screen room and the comfort and convenience of a three-season porch.
Xtend windows slide up and down on smooth tracks, giving you up to 75% open airflow when you want it — and a clear, weathertight seal when you don't. Glass and screen are both built into the same track system, so there's no separate screen to install, store, or lose. The panels are made with Flexible Vinyl Glazing that blocks UV rays without blocking your view. Each unit is custom-built to your exact opening, so installation is straightforward with no structural modifications needed.
Because they're maintenance-free, you'll spend more time enjoying your porch than taking care of it.
