Rated 4.6 out of 5 by 55 reviewers.
Rated 5.0 out of 5.0 by Glass Block Window Windows were delivered in about a week vs the 30 days promised. Were sitting on my front porch before I knew they were shipped. Well packaged and in good shape when delivered. Silicone glue used to assemble blocks much sturdier than conventional grout and did not require a band around the assembled window. Close fit of individual blocks make slight irregularities in the assembly obvious up close but not noticeable from a distance. Installation instructions were great except would have helped if they had mentioned that Type S mortar is recommended. October 27, 2015
Rated 5.0 out of 5.0 by basement window with Dryer Vent Easy to install good window Nice looking this is what i want September 8, 2014
Rated 5.0 out of 5.0 by Decora Glass Block Window with Vent I bought this window to be used in my bathroom that I am remodeling. It is in our shower area and I thought it would look good with the ceramic tiles surrounding it. I was right! It looks great and the vent makes it perfect for a bathroom. It lets in all the light you could possibly want without the neighbors being able to see in. The vent allows the steam from the shower to be vented out even while your in the shower. According to my carpenter it is the perfect depth for the wall and it was easy to frame in. I've already recommended it to a couple people I know that are also remodeling. December 27, 2007
Rated 5.0 out of 5.0 by Great Quality and Versatile! I'm so happy with my window now. This prefab is such a great idea. I turned it sideways for a bathroom narrow window and it looks good. The vent is next to the shower and it has an elegant finished look. We framed it out and stuck it in the old metal casing from a louvered window. Just silicone and paint. Perfect custom fit. Love it.

Rated 5.0 out of 5.0 by basement window let's the light in The windows are sturdy and fairly easy to install. They provide light and privacy. We were able to remove old and install new in one afternoon. Love the small vent screen built-in. July 16, 2014
Rated 5.0 out of 5.0 by Does its job without frills I had previously purchased and installed two of these units which I picked up at the Home Depot in Delafield WI. I was really satisfied with the way they were easily installed. They provide a much tighter seal from the elements than did the original storm and screen wood windows. I would be willing to pay a slightly higher price for a better and higher quality operating window being a part of the glass block unit.. Overall, I am very satisfied with this product and would recommend it to others. January 24, 2012
Rated 4.0 out of 5.0 by Replacement of a damaged basement window Was exact size to replace damaged window and of good quality. April 22, 2015
Rated 5.0 out of 5.0 by This product is great for basements. We love the nonvisibility so we don't have to have curtains and yet, we can let in fresh air! May 22, 2012
