31 in. x 11.5 in. Diamond Pattern Glass Block Window is rated 4.0 out of 5 by 6.
Rated 5 out of 5 by from Closet window replacement At 69 I decided to install these myself. This is one of two windows. Started at 9 am, removing all glass from the old casements and then with a saws all, removed the aluminum frames. Cleaned and wedged 2 new glass block windows in position and cemented joints. You may need a second hand inside to help position and wedge in place. Used 1-60 pound bag of Quickrete Mortar Mix. . Completed at 2 with a good lunch. Some prep work for wedges and spacers the day before. Trimmed inside the following day. What an improvement. No more cold air this winter. Lets the light in, with privacy. Sorry, I would have taken a before picture if I would have known of this review earlier.

Rated 5 out of 5 by from Easy install, quick shipping. Product was easy to install and the blocks were caulked together well. Easy to install with type S mortar mix.

Rated 4 out of 5 by from Much better Follow Up Review: Received the second window which was much better than the first, with all segments of the block aligning with each other. It appears these windows are constructed too order. Once again the order was received in a timely manner and the window was well protected with bubble wrap. Unfortunately the caulk must not have been dry prior to packaging so the bubble wrap had to be torn and cut off the window, not too big of a deal but a little annoying.

Rated 1 out of 5 by from Disappointing I ordered this window and it was received in a very timely manner. Unfortunately after it was unpacked we discovered that the 8 individual glass block units weren't aligned with each other. Instead of the joints being straight, the glass blocks were offset up to 3/8". We ordered a second window since the wall opening had all ready been constructed to receive this size piece...My fingers are crossed. Automated robot must have had a late night

Rated 4 out of 5 by from Functional solution for lighting a dark area We build a frame around this glass block to install in a hallway that needed some light but also privacy. It was fairly easy to do and effective.
