What Customers Are Saying

The glass block window is generally well-received, with customers praising its quality, ease of installation, and ability to provide privacy while allowing natural light. However, some users have reported issues with the alignment and construction, as well as concerns about the silicone quality and lack of detailed installation instructions. Overall, the product is considered a good value, though some suggest assembling the individual blocks themselves may be preferable.

My opening is fairly large so they delivered the window in two pieces. I wish they had an option for me to buy the glue to bond the two pieces together, but i bought an adhesive which worked fine.it is a beautiful high quality window.

Should have been better

It was a glass block window. Whoever built the window wasn't very careful aligning the blocks. Each row is skewed at least an eighth of an inch, so it is about 1/4 off top to bottom. Now, i have to decide if I return it, cut it apart and fix it or just use it the way it is. If I do use it like that, I still have to buy some more silicon to fix all the gaps they left everywhere. maybe next time I will just buy the blocks. the pickup was fine though.
