Customer Questions & Answers

actual dimenstions

Rough opening is 42.5" width x 27" high. Will the 42.5" x 27.5" window fit?
Asked by: ghgh
The actual dimensions of the 44x28" Guardwise window is 42-1/2 x 27-1/2 ans os, it will not fit into your openin. You would need to go to the next size smaller. 42x26 with an actual dimension of 40-3/4" x 25" for that opening.

does it come as one unit, or do you have to install each block individually?

Asked by: John
The GuardWise Windows are premade frameless wintows. The blocks are siliconed together.

Customer Reviews

20 in. x 48 in. x 3 in. GuardWise Vented IceScapes Pattern Glass Block Window is rated 4.6 out of 5 by 25.
Rated 5 out of 5 by from Perfect product. I needed a window for a bathroom we are remodeling. I wanted the block glass, but also liked the way this one would vent. It has been a perfect choice.

Rated 5 out of 5 by from 24 In. X 24 In. Glass Block Basement Window/Vent We had planned to install individual glass blocks for a window into our wood frame house for privacy. This fully assembled window was a dream to install. Very high quality with excellent jointing material made the install a breeze, even into a wood framed home. The Icescapes design has excellent light transmission as the light can easily pass through but visibility is deterred, exactly what we wanted. The vent is an added bonus.

Rated 5 out of 5 by from These windows are solid as a rock and heavy. These windows are exceptional. It feels warmer in the basement and I feel safer and more secure with them installed!

Rated 5 out of 5 by from Love the look of this window! We were looking to replace the old cracked aluminum windows in our basement but wanted some privacy as well as energy efficiency. This meets all our requirements. Installation wasn't quite as easy as indicated by some of the other reviews. One said 30 minutes. We got the closest size replacement for our opening, and by the time we leveled the window and mortared all around, we had spent close to two hours per window. The hardest part was getting mortar into the low clearance of the opening. We are experienced DIYers. Once finished though, we are quite happy with the results!

Rated 1 out of 5 by from questionable size I had a opening of 36" x25" so I ordered this window. The window came, however the over size is 30.5" x 19". Disappointing! I needed to make another trip to Home Depot to purchase 2x6 to fill the opening so that the windows would be secure. Then of the glass blocks were a little larger than the rest so I needed to grind off a little so that it fit into the opening.

Rated 2 out of 5 by from disappointed this window was order thinking it was the actual size of the product, it was not. The product was two (2) inches shorter in length and one (1) inch shorter height wise. I needed to go back to the store to purchase more materials to fit the opening of 36" x 22".

Rated 5 out of 5 by from Easy to install The window installed easily and looks good. It was my first time installing a glass block window and went smooth. The vent is nice to have. Have already bought another of the same window and will buy more

Rated 5 out of 5 by from Just what I Needed This was the perfect choice for a bathroom window I needed to replace. Since the window is in a shower area, the privacy this window afforded was excellent and the screened vent that opens up will allow fresh air in after a steamy shower. I would definately recommmend this window.
