Rated 4.6 out of 5 by 48 reviewers.
Rated 5.0 out of 5.0 by Great Value! These windows have been great in replacing old metal drafty one in basements. I use PVC Trim boards and mouldings that will not rot to trim out the windows with a more finished look. February 25, 2014
Rated 5.0 out of 5.0 by love the look, the price, and the quality Wiindow went in with ease. Looks great our shower and will serve us just the way we wanted! April 28, 2013
Rated 4.0 out of 5.0 by Nice window but check for corner chips A very nice window and easy to install once you figure out how the nailing fins work (no instructions on how to use the nailing fins included or on any website I could find). You need to watch out for chips on the corners of the blocks, either from shipping or manufacturing. Not easily visible, but very dangerous if you wipe your hand across the window. Needed to return half of my order due to chips and reorder. Still very happy with the look after installed. October 20, 2014
Rated 4.0 out of 5.0 by Glass Block window Excellent product and easy to install. It would be nice if they included instructions for the plastic mounting pieces included. October 2, 2014
Rated 5.0 out of 5.0 by Great window, great price Great window. Used in basement remodeling. Very heavy and sturdy. Screwed in to pressure treated wood then caulked. Two person installation to level and secure. Well worth the Money! July 31, 2012
Rated 5.0 out of 5.0 by easy to install I am a do it yourself home improvement person. I recently had an addition built on my garage, the original part is cinder block I have installed two of these windows using mortar very simple. Excellent product, highly recommended. If I had a place too use these in my house I would buy more. September 5, 2013
Rated 5.0 out of 5.0 by Really beautiful window The window is very pretty. Its real glass so the price is a great value. We installed it ourselves but man had we had it to do over we would have enlisted a lot more help. It's heavy!!! So for a 57 year old man and a 55 year old woman, it was quite the chore. But, worth it. Great quality window. We still have some trim work to do on it, but here is a photo of it from outside at night. April 15, 2015
Rated 5.0 out of 5.0 by exactly what we wanted We needed more light in our walk-in shower so after much thought found this window. It is perfect installed in the wall of our shower - looks great and lets in the light we needed. Home Depot shipped if much faster than we expected so that was great. The only problem is, it's very heavy so lifting it overhead was a bit of a challenge for my husband. It also came in a flimsy box for it's weight so it was torn open from the handling of UPS. But, it was packed very well and no damage. May 1, 2012
