Porchwerx, LLC is based in Lake City, Minnesota. We are entrepreneurs and we were looking for a better way to enjoy our porches.

Putting screens on and taking them off each season was growing old. And only having screens on in the warm seasons didn’t provide protection from the elements. (Rain, pollen, dust, high winds… you know if you have a screened-in porch)

Hence the birth of the expanse™ window. The best of porch living. Screens without having to look through them. Screens that retract when the weather calls for it. Clear views of your favorite backgrounds, your front or backyard.

With so many great characteristics, that makes the expanse™ window system great for other venues such as: golf courses, restaurants, ponds, lakes, mountain tops any place with customers and a view.

With expanse™ windows the possibilities – the PORCHABILITIES – are endless.

Let us help you expanse™ your porch.
