Rated 4.2 out of 5 by 33 reviewers.
Rated 5.0 out of 5.0 by Beautiful window - Heavy! Purchased the 48" x 48" window on line. It arrived earlier than promised, which was right on time for our renovation project. The guys at the local HomeDepot put it into my truck, and then my wife and I took it out once we got home. This is a beautiful window. But all that glass is heavy. Shipping weight, (free to my local HD store) was 199 lbs. We had to be creative in moving and installing the thing. While the window is beautiful, it is also slightly bowed out (about 1/4") at the center. That is why I gave it four stars for quality. Once it was installed, the bow became unnoticeable. But when installing, the bow plus non-square window rough opening in my house, made things a little challenging. At the end of the day, the thing looks great. I would purchase this again.

Rated 5.0 out of 5.0 by Great-looking unit very simple to install Without reservation I would recommend this product. Yes it was very heavy but with a little help from friends the window went in very simply. January 21, 2015
Rated 4.0 out of 5.0 by Good easy to install window! Nailing strips worked perfect for my installation, Vary easy to install. April 4, 2013
Rated 5.0 out of 5.0 by Excellant quality. Easy to install. Dilevery was great. Very nice product. It was delivered by UPS right to my house with no problems. (it was a little heavy). I mounted it easily with the included nailing strips. The only thing I found out is that you need to tell them when you order wich way it will be mounted. I guess this is because there are drain holes drilled in the frame during the assembly of the blocks. Overall a great product. June 26, 2011
Rated 5.0 out of 5.0 by glass block window It was so nice to be able to purchase whole windows instead of individual glass blocks that require some knowledge or talent to assemble into a whole window. This was the perfect solution to replacing broken traditional basement windows. They provide more security than basement windows & still let in the light. You can't open them but the look is nicer & they provide privacy traditional basement windows do not. It is also nice the windows come in a couple different styles. December 18, 2014
Rated 1.0 out of 5.0 by Window a joke & delivery a joke The vinyl trim around it is uneven The blocks edges are not flush to each other If you are an installer, and your customer is picky They will turn it down in a heart beat Please find another window The first one I got was horrible I reordered. The second one was no different I ate the cost of the window. Installed blocks one at a time Because, it has to look good for me to walk away From a job. If a ugly window is ok. Than This is the one for you Ups rolled it out of their truck twice February 15, 2012
Rated 5.0 out of 5.0 by Nice solid window.. This looks great! We bought this to replace our large bathroom window with a small privacy window and very happy with results. Don't bother ordering the video from the window company about installing. The video is the same very basic video that is on the internet. Easy installation. March 13, 2012
Rated 4.0 out of 5.0 by solid product for very reasonable price After installing four windows and looking at the finished product, I must say it is an outstanding value for the money. Good quality product when installed properly (easy install) creates a very good aesthetic effect. December 30, 2014
