Rated 4.4 out of 5 by 23 reviewers.
Rated 4.0 out of 5.0 by Good (standard) glass blockwindow, no instructions I purchased these windows over other similar windows based on vendor's claims it offered more flexible installation options (nail or silicone, outside or inside). While it does come with optional nailing strips, that's about the only feature included. The window is pretty much standard (no complaints), but the installation instructions are non-existent. The instructions are a sticker on the window that says "can be installed with nailing strips or silicone" and that's about it. I've installed a couple of dozen windows in my house to date and I still would have appreciated a page or two of installation instructions/hints/suggestions. February 8, 2010
Rated 5.0 out of 5.0 by Good Quality well built I purchased one of these windows to replace my existing standard metal/glass basement windows along with 4 others that did not have a vent. Product was well made and the quality of the glass block was very good. I found no defects and while some of the outside shipping boxes were damaged the inside product was very well protected with its own cardboard box and plenty of additional bubble wrap. (Lots of bubble wrap!) Glass blocks were made of very clear & clean looking glass with no internal or surface defects. TIP: Instructions that came with my windows did not point out that there are two weep holes in the bottom of one side of the frame. These holes must not be covered by frames, caulk or mortar.

Rated 5.0 out of 5.0 by Great Value! Purchased for my bathroom. Was everything that I wanted. Great window for the price. Love the vent w/screen. May 2, 2012
Rated 5.0 out of 5.0 by Better than I expected Based off of the other reviews we bought three of these windows to replace the old, dated, metal framed ones in our basement. My husband and father in law put all three of these plus one regular window in, in one day. They said they were a breeze! They went right in! The frames of the old windows were cemented into the walls so we had to leave the old frame and cement these windows in, which was kinda what they planned for anyways. We also noticed, compared to the old windows, that these are much more energy efficient. The old windows you could walk by and feel the heat coming in from the outside. These you feel nothing. They are fantastic! We've even put the little window to good use feeding in the hose for the compressor as they are doing some framing as well. Father in Law loved the ease of the installation and my sister in law is now going to be ordering some for her house as well. Great, great buy! Would recommend 100%. July 8, 2013
Rated 5.0 out of 5.0 by A very practical replacement for my bathroom window. While looking for a replacement window for my bathroom (shower) I came across this one on the website. This unit turned out to be a wise choice for my particular application. The installation was very simple and although this window is designed for basement applications it worked great in the shower area. The glass block design lets in far greater natural light than the previous opaque window and the vented opening helps in venting damp air from the bathroom. July 13, 2011
Rated 5.0 out of 5.0 by Good quality windows Installed them myself in the basement as a replacement for original 14 years old windows. Very nicely made. Installation was done with mortar. They look great. Nothing negative to say about them. October 13, 2011
Rated 5.0 out of 5.0 by glass block window, with or w/o vent great value, extremely well built & very nice to look at January 14, 2015
Rated 5.0 out of 5.0 by wonderful windows Good window. simple and easy install. Top quality in my opinion. Very heavy for its size. My wife is happy with these replacement windows, and so am I. We will order two more for the other basement windows shortly! May 15, 2012
