Questions & Answers

My current window and frame is 37.5 W and 37 H. Would the window I need be 36.73x36.75?
ByOct 7, 2026
1 Answer | 
Answer This Question

This would be a very tight fit on your height and would suggest a next size down with 3836VDC. Window size would be ~ 36.75 x 34.75 and more room to finish off and secure in opening.

    my rough in is 20in x 20in will the 19.25x19.25 size work?

    Answer This Question

    A 19.25 inch x 19.25 inch glass block window will fit in your 20 inch x 20 inch rough opening. Be careful with tight fits and double measure to ensure square openings.

          I need to buy five of these for my cement basement. My window openings are mostly 31.5” x 18.75”; however, one is 30.75” x 18. Would the 31 x 17.25” Home Depot window be perfect or too big?
          ByApr 13, 2026
          1 Answer | 
          Answer This Question

          The 31 in. window would be a tad too big. The window assembly measures at 31 inches wide and physically won't fit into your 30.75 inch opening, unfortunately.

            I want this same type of window. I don’t see it in your product, but I’m sure I bought this one from you.

              Answer This Question

              Yes, this window can be installed in a wood frame. Please refer to the "Installation Guide" pdf in the Product Details section for guidelines regarding this type of installation.

                Can the window be installed sideways, to operate like a casement?
                ByApr 19, 2025
                1 Answer | 
                Answer This Question

                The vent in this window will open if the window is installed sideways. However, any trim that overlaps the edge of the vent will most likely impact the ability to open the vent. We also cannot guarantee the performance of this vent in severe weather if installed sideways, since the vent was manufactured with horizontal installation in mind.

                  The width of my tiled shower window opening is 23.50 inches. The old glass block windows were 23.25 inches wide. Grout was used to fill in the .25 gap on both the left and right sides combined. Will a new 23.25 inch wide glass block window work?
                  BySep 21, 2024
                  1 Answer | 
                  Answer This Question

                  You can use a new 23.25 inch wide glass block window, but the fit will be very tight. We generally recommend between 0.5 - 2 inches of room between the rough opening and glass block window, due to more leeway during installation.

                    The Clearly Secure glass block pre-assembled windows with air vent are beautiful. We had our mason install them for us. They let in light, but do not allow a person to see in clearly. The glass-block assembly are well-made and very secure. We purchased four for our new build and they exceed our expectations.

                    Awful quality
                    Just received today held together by tiny globs of caulk you’d think it would be a little more install ready when you’re paying the price to be able to just slap it in out of the 2 I received one needs major repair and other is ok but still need repair before I can install so I don’t recommend just get the blocks and you’ll be able to do a better caulk job for 1/3 of the price

                      Shipping damage
                      Unfortunately this product arrived with damaged silicone seams. The silicone used to hold the blocks came loose and half of the window was not connected to the other half. Home Depot graciously discounted the item and recommended a product so that could repair the damaged seams. I thought that reconnecting the seams would solve my problem, but when installing the block, the seam popped apart again and shattered all over my concrete floor. I was not successful in installing this product, likely due to the shipping damage.

                        Window came in great condition. Sat in the rough opening very nicely. Used Mapei brand glass block window mortar for the install. Couldn’t find this specific size window at any other retailer. Let’s a lot of light in and the hopper window operates smooth

                        Nightmare project finished today. Ordered window and it arrived with the blocks not glued together. Returned. Reordered. Since defect asked for an expedite through store and Home Depot customer service. Denied wait 2 weeks. Received replacement order. One block separated and not glued on. Asked for expedite through Home Depot Facebook page. Also denied by company. Contacted company directly ( Pittsburgh glass block). No relief. Ordered replacement arrive 2 week later. Front edge of window not glued. Looked like a hinge. Returned to store. Again contacted the company and Home Depot corporate compliance to expedite. Received a good product two weeks later. 3 defective orders and could not get them to expedite Before some one ask, needed to get matching window for the other 3 in my basement.

                          Bad packaging lead to multiple damaged orders
                          The windows themselves are great. It's getting them in one piece that seems impossible. The packaging is a major issue. We ended up having to return a whole order because of damage and the replacement process was a hassle. We ended up just reordering and picking up in the store where we checked over everything, and found three more windows had broken silicone seals and some scratched yet again. We ended up getting them discounted and had to buy silicone caulk to fix the broken seams. They really need to package these windows better if they can't even make it to the store in one piece.

                              We like that the window lets light, yet provides privacy. We purchased the window to replace a solid window in a shower, as we were remodeling. We like that it has an opening, which will allow better ventilation than we had previously. It was just installed within the past week and we'll be using the shower for the first time today. We are pleased with the appearance. The only issue we had was needing to return the first one, due to damage during shipment. The replacement order came sooner than expected and was all in one piece. It did need to have more silicone added when the workers put it in the wall, but otherwise seems to be what we hoped it would be.

                              Exceeded ecpectations. Heavy duty glass panel, exact measurements, installed easily, should have done it a long time ago. Made a huge difference in keeping the basement warmer!
