Rated 4.4 out of 5 by 23 reviewers.
Rated 5.0 out of 5.0 by Better than I expected Based off of the other reviews we bought three of these windows to replace the old, dated, metal framed ones in our basement. My husband and father in law put all three of these plus one regular window in, in one day. They said they were a breeze! They went right in! The frames of the old windows were cemented into the walls so we had to leave the old frame and cement these windows in, which was kinda what they planned for anyways. We also noticed, compared to the old windows, that these are much more energy efficient. The old windows you could walk by and feel the heat coming in from the outside. These you feel nothing. They are fantastic! We've even put the little window to good use feeding in the hose for the compressor as they are doing some framing as well. Father in Law loved the ease of the installation and my sister in law is now going to be ordering some for her house as well. Great, great buy! Would recommend 100%. July 8, 2013
Rated 5.0 out of 5.0 by Great Value! Purchased for my bathroom. Was everything that I wanted. Great window for the price. Love the vent w/screen. May 2, 2012
Rated 5.0 out of 5.0 by A very practical replacement for my bathroom window. While looking for a replacement window for my bathroom (shower) I came across this one on the website. This unit turned out to be a wise choice for my particular application. The installation was very simple and although this window is designed for basement applications it worked great in the shower area. The glass block design lets in far greater natural light than the previous opaque window and the vented opening helps in venting damp air from the bathroom. July 13, 2011
