Customer Questions & Answers

is this solid glass block window waterproof?

If I use this window in a wall I am building in the wall of my shower, is it waterproof?
Asked by: summerdays
This window is ok to use in a shower. It will need to be attached at all four sides to structural framing with a complete seal around the perimeter.

can i use these glass blocks in a shower wall? If so, are they a "clear" color with grout?

Asked by: summerdaze
A shower wall should be built on site block by block using the Premiere Series (4" thick) glass blocks with either the ProVantage II or the Mortar II Installation. the GuardWise windows are clear glass with patterns and adhered together with Pittsburgh Corning Glass Block Sealant (silicone)

Can two windows be installed side by side to make it appears as one large window

Asked by: Square
To install two windows side by side, we recommend applying two beads of Pittsburgh Corning Glass Block Sealant along the one window, insert a Thinline Track Spacer (item number 120610), apply two beads of sealant along the spacer and then the second window. Allow the sealant to cure for 24 hours and then apply a bead of sealant along the joint on the interior and exterior of the window.

21.25 in. x 21.5 in. x 3 in. GuardWise Decora Pattern Solid Glass Block Window is rated 4.5 out of 5 by 28.
Rated 5 out of 5 by from Glass Block This was an excellent buy for our remodeling of a bathroom. Ordered online and received within a week, plus they had free shipping. Great construction and good directions on how to install. They should have mention to use their premiere mortar spacers to get the proper fit without error. But all and all this was a great investment. Looks great in the bathroom. Ready to use again.

Rated 3 out of 5 by from Looks Good The window looks good, but it's bowed in the middle. The window deviates 3/8" from the middle to sides. The window specifications are incorrect in the description. I called the manufacturer before I framed the opening and he confirmed 46.5 x 35.5 assembled dimensions, but when the window arrived, it was 46.5 X 34.5. I had to modify the sill and weatherproof again. Between the bow and wrong advertised dimensions, window was more difficult to install than it should have been.

Rated 5 out of 5 by from Other than price this product met or exceeded all expectations. Beautiful window! Had it installed in our bathroom. Let's in tons of light and will not rot like the window I replaced. Contractor had no issues installing. I ordered 2 more windows from a different company because of a vent feature that this one did not have. They were cheaper but my contractor said they were not as good quality because of the type and amount of silicon used. You get what you pay for.

Rated 1 out of 5 by from Fell apart due to poor construction I was really excited to receive this already assembled, until I received it. I had already built 7 glass block windows for my basement, so I have a good idea of strong, quality construction. This window fell apart at the silicone seams when I opened the box. Yes, it was shipped; however, it had no spacers between the blocks only a slight amount of silicon. I accidentally dropped a well constructed glass block window from a basement window to the basement CONCRETE floor, it didn't break.

Rated 5 out of 5 by from Great for DYI These blocks come pre assembled and that makes it easy to install. The only drawback is that not all windows are exactly the same size. The dimensions for the same window can vary as much as 1/2". So measure every window to make sure you make the correct rough in. I didn't and had to move a stud 1/2" to make the two windows fit the space.

Rated 5 out of 5 by from Perfect fit window panel The glassblock window panels were made exactly to the online specs and fit perfectly in my basement casement windows. The factory silicone joints between the blocks are strong and neat.

Rated 5 out of 5 by from 34.75 IN. X 25.5 IN. X 3 IN. GUARDWISE DECORA PATTERN SOLID GLASS BLOCK WINDOW Very well pleased with quality, construction, and ease of installation of the glass block window. I was a little apprehensive reading about the quality of the construction of the windows, but no issues here. Also, I had to order online since it appears they do not carry this in many stores now. That was a little inconvenient since I like to see and touch what I am working with. They were shipped and received in about 10 days.
