"Zen Windows advertises that they make things easy, and that they do. Zen windows doesn’t just make things easy, they have quality products, reasonable prices and exceptional service. We just had an entry door replaced and everyone we worked with was great. While they don’t push you into buying any products, they do go out of the way to help you make the right decisions. Everything went exactly as they told us, the installers were top notch and the finished product looks great. Without hesitation, we would highly recommend Zen Windows to anyone looking for doors or windows."

"We just had Unicorp install new windows throughout our entire house. The window quality is excellent and the installation went very well. We were replacing 55 years old windows - and were very happy with the entire process, from selection, exterior color choices, and finally installation."

"Excellent work. The person who assisted us was gruff and no-nonsense, but professional. He asked that we send a photo of the window, which we did. He then came out and measured the window. He came back a couple of days later, and completed the work. The window looks fantastic, and we are very pleased with his work."

Windows FAQs, answered by experts

Awning windows can have screens, but it depends on your manufacturer. If your awning window does have a screen, it will be on the interior side so it doesn’t get in the way when you crank the window open. Having the screen on the inner part of the window also makes it easier to clean from inside your home.

To tell if a window is single or double-pane, focus on the edge. Double-pane windows have two glass layers separated by a spacer, which you can usually see around the edges. For single-pane windows, it’s just one sheet of glass. Another easy trick: shine a light at the window—single-pane glass reflects once, while double-pane glass reflects twice. Lastly, if you feel both sides of the glass on a cold day, double-paned windows will feel warmer because of the insulating gap between the panes.

Yes. Vinyl windows have a PVC frame that wraps around a glass panel that is usually made up of two thinner glass panels separated by an insulating, noise-absorbing airspace. Some vinyl windows are triple-glazed, with three insulating air panels within them. This glass helps keep your interior quiet from outside noise while its insulating qualities help your space stay cool in the summer and warm in the winter.

No, not every window has movable sashes. Many fixed or stationary windows that were intended only to provide views and sunlight still have inoperable sashes that allow them to match the rest of the windows in a home. These are called sash-set fixed windows. They are created by glazing a window into a sash that is secured to a frame.

You can add any type of window to a brick house, so long as the window has proper support. Windows with wider openings and windows in brick walls will need a lintel to support the extra weight above the window frame. A lintel is a support beam that distributes the weight from above evenly around the window.
