About This Product

Clearly Secure individual glass blocks combine the qualities of beauty, performance and practicality in a material that permits the flow of light. Glass blocks are a special building material made of glass and laid similarly to brick or concrete blocks. Used in partitions, shower walls, curtain walls and room dividers, glass block permits light from one space to travel to another, helping to save on illumination costs. Glass block's properties lend style and privacy while also helping to muffle sound. Additionally, individual glass block may be combined with other Clearly Secure glass blocks and Clearly Secure hopper and dryer vents to build enhanced privacy and security windows for basements, bathrooms, kitchens, garages, transoms, door sidelights, offices and much more.

    Rough opening 36x60 can you suggest the size to order
    ByFeb 24, 2026
    1 Answer | 
    Answer This Question

    We currently do not offer a single panel assembly that fits a 36 in. x 60 in. opening. However, you may use two separate window panels to build a combined panel that fits your opening. Two panels of Internet # 206974567 | Model # 3630SIC would result in a 34.75 in. x 58 in. panel assembly, and you can use glass block silicone to adhere the panels together.

            My rough Opening is 48 inches X 48 Inches Exactly. Which Model Type Block n X n do I buy?
            ByMay 27, 2025
            1 Answer | 
            Answer This Question

            We generally recommend a gap of 0.5 to 2 inches around the window for room to mortar the window in the opening. Currently, we do not offer a model that properly fits a 48 inch x 48 inch rough opening. However, you could assemble the glass blocks piece by piece. If you want to stick to pre-assembled windows, then we generally recommend buying two smaller windows and combining them during installation using a silicone seam kit (Internet # 301230204 | Model # SEAMKIT). Combining two of the 46.5 inch x 23.25 inch windows (Internet # 300502102 Model # 4824SIC) during installation will result in a 46.5 inch x 46.5 inch finished window. Please be mindful that glass block windows weigh considerably more than their vinyl counterparts, due to glass blocks being made of real, thick glass.

              If the blocks are 8 X 8 how can a 4 X 6 block only be 31 inches X 47 inches?
              ByAug 18, 2024
              1 Answer | 
              Answer This Question

              Glass block sizes are referred to by nominal sizes according to industry standards - similar to lumber standards of referring to 1.5 in. x 3.5 in. lumber as 2x4. The nominal 8 in. x 8 in. glass block used in this window have actual dimensions of 7.75 in. x 7.75 in. So, the four by six configuration of nominal 8x8 glass blocks in this window give an actual finished dimension of 31 inches by 46.5 inches.

                For a space 14.5" W x 48" H rough opening, what size of bricks should I use? 8x6? 6x6? what is the end-cap piece for? Should I allow extra space for the mortar or channel?
                ByJun 14, 2024
                1 Answer | 
                Answer This Question

                We typically recommend the rough opening be 0.5 in. - 2 in. larger than a glass block window that you plan on mortaring in place. For a 14.5 in. x 48 in. rough opening you could use Internet # 300502105 Model # 4814SIC. This glass block window is 13.5 in. x 46.5 in. and consists of six 6 in. x 8 in. x 3 in. and six 8 in. x 8 in. x 3 in. nominal glass blocks. Please refer to the video section & Product Details section PDFs for further details regarding glass block window installation. Feel free to give us a call if anything is unclear and you would like more clarification on what window or glass block configuration is appropriate for your opening. Thank You!

                  Worked fairly well for what we were looking for. We had an old leaky bathroom window and we didn't want a custom vinyl window. We have a brick house. Install was easy, used mortar to install Should last us a long time

                  The windows were as expected. They are nice. The assemblers could do a bit better job with the assembly adhesive but all in all they are very nice.

                  Great 1930's Bathroom Window Replacement
                  Our 1935 build home had the classic wooden window over the tub. This is a great replacement window for when the space is converted to a shower-tub combo. I was on the fence on the style, because these were so popular in the 80's but vinyl windows look so cheap I think this is the better choice. It's great how many sizes this window comes in, ours was a perfect fit. Pickup at the store was awful (took almost an hour for no reason) but otherwise recommend.

                    Good Window for the Price
                    Good window, but one of the seams was loose when it arrived. Now that it is mortared in it wont go anywhere and the seam was filled, but more frustrating than anything else hence the docked star.

                      I like that these now these windows have silicon between the panes so they are less likely to crack like my old cement glass block windows did.

                      My UPS man was in awe that this was available in a window. Mine was 70 lbs., after 4 days it was time for the install. Mid-top was not siliconed on one side and it tiled, and I freaked a bit. luckily I had clear silicone on hand and it went in great. My suggestion: Use nails to support, the wedges are kinda hard to remove. HIGHLY RECOMMEND.

                      PERFECT!
                      Were remodeling our bathroom and hemmed and hawed as to whether we were gonna replace the window in the shower. Decided to go for it. Had a panick thinking it was two inches too big for our opening and thought we had to exchange it but once the installer got here we quickly realized it was actually the perfect size once he removed the old window frame. Were not done yet but its transformed the space. So so so happy i went with my gut and ordered this window. Even if it did delay our bathroom completion almost two weeks

                        This pre-fab glass block window is the perfect solution to remodel a walk-in shower with an old double-hung wood sash window above an old cast iron tub. This window size was close to the old window rough opening size. After tear out, I used PVC trim lumber (water proof) to frame in the finished opening to the window size plus 1/2-inch allowance (1/4 -inch all around the window perimeter). At 160 pounds (about the same as a 15.5-gallon keg of beer) it’s heavy, but I used 2-inch wide strap around the window and a wind-up hoist to lift it into position (with a little help from grandma). I think using a pre-fab glass block unit is much better than attempting to build a similar unit one block at a time, and probably costs less overall, plus you get perfect grout lines guaranteed.
