Hi Scott, you can use a silicone seam kit (model # SEAMKIT) with window model # 2232SDC and model # 2224SDC to create a symmetrical combined window. The finished product will have nominal 8x8 glass blocks on the left and right columns, and nominal 6x8 glass blocks in the center column.

        Answer This Question

        Hi Jeff, you only need glass block silicone to join glass block windows vertically. A glass block spacer is only required when you stack the windows and connect them at a horizontal joint. You can find glass block silicone with Internet # 301277556 | Model # R2BSILT. We would also recommend using two 28.75 in. x 17.25 in. windows to create a total combined window of 57.5 in. x 17.25 in. so that you have room to mortar the window into the opening. This can be found with Internet # 206754365 | Model # 3018SDCA closer fit in width is possible, however the 28.75 in. x 17.25 in. windows use uniform block in the assembly, which will create a symmetric finished product. Please give us a call if you would like further detailed assistance. Thank You!

                  I was looking at just buying the glass block and saw this assembled window. It's installed and looks great. It was well packed and arrived without a chip or broken glue joint. I'd buy it again! I just have to drywall and trim and paint.

                  Glass block window came packaged very well. Once we opened it up, we realized it wasn’t strapped together. Only the blocks were siliconed together. One row was broke apart before we took it out of the box. We had to take tie wire and strap the window together. Which should have been done by the factory. Once installed, it looks amazing.

                  I bought 3 of these windows, one with an integral dryer vent, and they are great. The windows are sized exactly, which makes planning and installing easier. They can be framed or mortared in (I did both) and they bring so much light into the space. Best of all, they are sturdy, heavy duty windows that provide significantly more protection than older, single pane windows.

                  Window was ordered and installed. It wasn’t until after it was installed that I noticed the blocks were not the same size. The four down on the left side are much larger than the rest of the blocks. It isn’t noticed until I point it out. I’ve never seen this type of window on any other home have different size blocks. It was easy to install and not very heavy. The blocks are not solid glass as they are hollow on the inside.
