Most of our customers come to us with a problem of high energy costs from heating and cooling bills, or noise problems from living on a busy street, or just by living nest to the guy who insists on mowing his lawn at 7 AM every Saturday morning. While Castle Window Covers provides the best solution for insulating your windows against extreme temperatures, as well as one of the best solutions for soundproof windows, we also solve a lot of other problems you may have due to your windows. IF YOU HAVE HISTORIC WINDOWS we can help you preserve the original beauty of your home, office or historical landmark. Castle Window Covers don't interfere with the structural integrity or classic beauty of your home or facility, and we eliminate the need for replacement windows - all for about half the cost.

IF YOU HAVE INEFFICIENT SINGLE-PANE WINDOWS BUT CAN'T AFFORD REPLACEMENT WINDOWS we are definitely your best answer. Our acrylic window covers insulate your windows better than dual- and even most triple-pane replacement, glass windows, and our cost is usually about half. On top of that, our insulating window system will significantly reduce your monthly energy bills for cooling and heating.
