Customer Questions & Answers

Please provide me a list of specific grout, caulk, and any other supplies I need for installing this window in an exiting window space. Thanks...

I need to purchase everything at once so that the installation will go smoothly. Thanks...
Asked by: Ranchgal
Our installation calls for these windows to be mortared at the sill and jambs and then expansion material at the head and that joint caulked. So in additon to the window,you will need a bag of Type S Glass Block Mortar, three 16" Expansion Strips and a tube of caulk.

looking for a 43.5 x 27 window

I noticed you had a 27 x 43.5 window available but no 43.5 x 27 with no vent. why is this and can it be installed backwards. Also the color states green? are the blocks green or does it have a green hue when lit. Im a professional mason by trade but also like to choose the easy route when messing with glass block. Thanks, Mason Louisville, Kentucky
Asked by: Mason
The actual size of a 44x28 inch GuardWise window is 42-1/2" x 27" - the width is listed first. For a 44x28 (actual 42-1/2" x 27") Decora Pattern without a vent the item number would be S4428DC. This window is 42-1/2" wide and 27" high. Some glass has a green tint due to the iron content in the sand used to make the glass. Our goal is to remove as much iron content as possible making the glass as clear as possible. (Note: we are addressing the size correction on this item)

how do I install a prefabed block window into a wooden frame, bricked exterior

it looks like your instructions are only for bricked opening. I am installing two windows together in one opening. Its a framed house that has a brick exterior. I understand motoring the exterior of the perimeter of the window but how do I secure the interior which will be wood?
Asked by: russ
To install a GuardWise window into a wood opening, you can follow the same instructions as for an installation into a cmu opening, however, since mortar does not adhere well to wood, you should apply a "stop" around the perimeter of the window on the inside and outside of the window after it is installed. You can use 1/4 round or other type of trim to accomplish this.

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)

Dimensions to Order

What dimensions should I order....I know I measure the opening of the basement window. But do I order a window exactly with those dimensions? In other words, how does the space needed for mortar play into the ordering process?
Asked by: Anonymous
The actual size of a 32x24" GuardWise window is 31x23-1/4" - so if your opening is 32x24" the 32x24" window will fit with enough space for your mortar joints.

If my rough opening is 28.5in x 41in is this 27in x 39.5in selection allowing for enough mortar to set the window?

Asked by: Jay

Can the windows be used to build a shower wall?

The wall needs to be 78in x 90 in tall and will be adjacent to a staircase, thus a frame can built to secure the window panels. Is there a limitation on the number of window panels that can be stacked/installed on top of each other?
Asked by: Anonymous
To build a shower wall, the Premiere Series 4" blocks would be recommended and the wall would be built on site block by block. You could use the ProVantage (silicone sealant) installaiton finishing the joints with grout. For a glass block panel near a staricase, the glass blocks would need to be attached at all four sides.

I have an opening 24" high x 72" wide. Can I put this two together? Will I need a special joiner? It will replace a 2x6 window, is it rated fireproof

Asked by: Anonymous
To attache two GuardWise Windows together, run a double bead of the Pittsburgh Corning Glass Block Sealant along the side of the window, install a ThinLine Track Spacer, run another double bead of the Glass Block Sealant on the spacer and install the second window. Allow the sealant to cure for 24 hours and the finish the joint on the interior and exterior with a bead of the Glass Block Sealant. Note: the rest of the window does not have spacers between the blocks and the spacer you use to connect the two panels may be visible through the blocks.

46.5 in. x 35.5 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 product as explained window came as stated and installation was a breeze, quality was tops. appearance after install was better than I had hoped for.

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.
