Rated 5.0 out of 5.0 by Windowless Wall?? I was looking for ways to increase sunlight coming into my home on the southern sides. I have two original windows on the southern side but I have four rooms. Two of the southern rooms has windowless walls that face to the south. However, I did not feel right about adding more of the same type of windows I have in two of the rooms. I was looking for a different kind of inlet for more sunlight and warmth during the wintertime. I was thinking about a sliding glass, but I already have one on the other side of my house. Glass blocks came to my mind and I wanted to install some on the bottom of the wall . I start investigating online and found one at Home Depot in a ready to install type of glass block window without any need to do any masonry work and stuff. I decide on this one because it comes with a small vent window in the middle. I will see how it turns out and I may install another identical one in another windowless room in the future.

Rated 5.0 out of 5.0 by i LOVE this window in my new bathroom I cannot attest to installation, as I paid my contractor to do it :) I had him install the vent section 'upside-down' so the opening is at the bottom which allows steam to escape and doesn't allow water to enter the opening. I LOVE glass cubes, and that is the FIRST and easiest decision I made in my bathroom upgrade. August 13, 2015
Rated 5.0 out of 5.0 by Good purchase the vented glass block windows arrived quicker then I expected, the installation was easy, they look nice, I am very happy with these windows. Glass block windows give me plenty of light, air and security all in a low maintenance package. September 6, 2015
Rated 5.0 out of 5.0 by Fantastic replacement windows for our basement These are substantial, quality windows that arrived quickly and safely at our little three-unit condo building. (Keep in mind the delivery is a sidewalk drop.) Our contractor was impressed and so were we, plus we're happy they're made in the USA. Our building is old so it wasn't a matter of just removing old windows and popping in new ones. There was crumbling old mortar and deteriorated wood to deal with. Even so, it was not a difficult process. The Decora pattern is beautiful and we get both the light and privacy we wanted. February 5, 2013
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 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 Looks better than I expected. The glass block window looks great in place of the old single pane aluminum framed crank out style window. I installed it in my basement bathroom. It adds more security, privacy and efficiency. The small window in the middle allows air circulation when wanted and looks good too. December 12, 2013
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
