Rated 4.6 out of 5 by 48 reviewers.
Rated 5.0 out of 5.0 by Great product The window arrived quickly and was packed tight so no damage at all.It looks great in my garage and allows light it. Tip for install: I used the glass block mortar. It was a little more expensive but looks great and was easy to work with. GET A MORTAR BAG! if you don't know it's a bag similar to a cake decorating bag. Makes the job way easier than trying to stuff the mortar in there. Also, do a search on the internet for installing glass block windows for additional installation directions. Take you time positioning the window and putting in the mortar. I saved $150 by doing this project myself. I plan to order a couple more for the laundry room. Another thing: THESE ARE MADE IN THE USA! September 1, 2012
Rated 5.0 out of 5.0 by I ordered & installed 2 of the Decora glass block windows. They have a very durable look & feel to them. Once I made up my mind on how to install them, they installed quickly & easily. I probably spent as much time mixing up the glass block mortar as I did actually putting the windows in. After the mortar cured, the windows are very strong & solid. I put them in the basement, which didn't have much of a view, just the window well really. But the Decora block reflects the green of plants growing around the window well, the blue sky and the window well, which I had painted white to add brightness to the basement, and creates a little mosaic pattern. Each block reflects the same image so it creates a repeated pattern. You can't tell exactly what you're looking at, but the pattern that is created is interesting so now there is a view where there used to be none. I know the windows are much more secure now and the Decora block offers privacy without the use of any window coverings. I'm seriously thinking about ordering 2 more, and the free shipping promotion you have going is what got me to order the first 2. Keep doing that sort of thing and I'll shop online more. June 2, 2006
Rated 5.0 out of 5.0 by nice product Nice windows. I am replacing 60 year old, metal frame, basement windows, so, of course they look a lot better. It takes me 2- 3 hours to remove and replace each window from start through cleanup. I set these windows with S type mortar and a grout bag. I bought both solid block and vented block and they both look outstanding installed. Pry bar to remove old window and shims, level, grout bag, and mortar to install. Great DIY job. October 23, 2012
Rated 5.0 out of 5.0 by Great value Received window quickly and was just right. Has made a great improvement on the looks of the window in the basement. No more drafts coming in. December 12, 2014
Rated 5.0 out of 5.0 by Easiest style window to install I bought this window to replace an old, cracked and dated sliding basement window. Despite being nearly the same size as the old window, this one lets in much more light and brightened the entire room, making it seem larger than it is. I knew I had no interest in the hassle of conventional windows or individual glass blocks, so I was glad to find this product. If you are a novice window installer, you can do this. The only reason I didn't rate the ease of install as "Excellent" was because you still have to deal with mortar (be sure you get mortar for glass blocks, not regular mortar). I rated the quality as "Good" rather than "Excellent" only because it looks to be put together with silicone caulk, which makes sense for something transported assembled, though. I will try to use the style window from now on, anytime I have to replace a basement or bathroom window. You will not regret your decision to use this. March 6, 2013
Rated 4.0 out of 5.0 by Windows arrived just as I imagined they would Easy to install, be sure to read other reviews for installation, grout bag was key May 28, 2013
Rated 5.0 out of 5.0 by Decora Pattern vented block glass window. This product gives the perfect visability that we wanted, along with improvement on the lighting in the room. We will be ordering a few more to finish out our basement. July 17, 2012
Rated 5.0 out of 5.0 by Quality product The window is of very good quality and was easy to install. Much easier than installing individual glass blocks and no more expensive. October 1, 2013
