Customer Questions & Answers

Do they have a hole?

I am wanting them for a craft and I was wondering if they are hollow and if they have any kind of a hole in them?
Asked by: Our7crazykids
No..we drill the hole ourselves with a special glass drill bit. The blocks are hollow.

How do I give the top a finished look when building shower wall

I'm building a shower wall and wondering how to give it a finished look at the top. Meaning how to cover the lips of the block
Asked by: kelkel
Thank you for your recent inquiry with The Home Depot. We have contacted the manufacture .They tell us you have the frame that goes around the glass block to hold in place to use as the finish look at to top. Just as long as your shower has straight panels supported on at least 3 sides We appreciate your business and look forward to serving you in the future. Thank you for shopping Home Depot.

Can I use Decora blocks to top a concrete block wall?

I have a garden wall roughly 43 feet long that's constructed of 8X16X6 concrete block. For the first roughly 27 feet the Decora would be only 1 high and for the remaining 16 feet the Decora would be 2 courses high. This is a norther California climate without freeze concerns. Is this a reasonable idea, and what would be the recommended construction method?
Asked by: LarryL
Glass Blocks can be used for exterior applications, however, we recommend that they are structurally attached at all four sides due to windloads. Glass Blocks are non load bearing so adequate provisions must be made for support of construction above the glass blocks. The maximum recommended width for glass blocks in an exterior application is 25'

Customer Reviews

Premiere 8 in. x 8 in. x 4 in. Decora Glass Blocks (8-Pack) is rated 4.7 out of 5 by 63.
Rated 5 out of 5 by from Beautiful when installed - let's in a dancing rainbow to a small bathroom Let's in light while still providing privacy. Installation in an old wall can be time consuming given the precision required to keep everything true for a single column. Had to purchase more rails and spacers than I needed due to only being sold in packs. Overall I'd do it again but question my idea of doing a whole shower wall sometime in the future. Bit pricey. Pittsburgh Corning provides excellent, detailed instructions on their website. Be sure to read them and watch the videos. Their app for creating a shopping list is great!

Rated 5 out of 5 by from Pittsburgh Premiere Decora Blocks in 8" x 8" x 4" I use the Pittsburgh Premiere Decora Glass Blocks in making my Lit Glass Blocks. I've been making these for a number of years. I've never had a problem with any of the blocks I have bought.

Rated 5 out of 5 by from The glass blocks are well made. The first thing about the Pittsburgh glass blocks is that they are made in America! I use them in a craft project and they are the perfect size and shape for my craft. I have found no blemishes and they stand up well to hot glue and transporting around to craft fairs.

Rated 5 out of 5 by from Good Glass Block for the price I used my Glass block to infill some old basement windows. The Glass is clear and lets lots of light in the basement. And they are distorted just enough to maintain privacy.

Rated 5 out of 5 by from Great product for my craft project! My mom and I got an idea for a Christmas craft project and were unable to find the 8"x8"x3" glass blocks anywhere within a 100 mile radius of where we live! I got onto Home Depot's website, ordered a couple of cases of exactly what I wanted and had them delivered right to my door FREE! The blocks are of excellent quality and were exactly what I was looking for!

Rated 5 out of 5 by from Very easy to work with The product was very easy to work with, and was very quick to install once you have a square opening. The whole thing is extremely strong, and the adhesive also a great idea.

Rated 5 out of 5 by from was better then expected All went well, arrived 2 days ahead of schedule. items were as expected.

Rated 5 out of 5 by from Easy to work with The block was easy to install using the Provantage track and spacer system and the Corning silicone. Was able to put up a U shape bar base of 10 wide with Hedron corners and 2 blocks on the sides, by 5 high in a matter of hours. The Hedron spacer system is a little clunky. Ensure the spacers are fully snapped together to avoid any extra space. They still result in a few 'sixteenths' higher than the square block at each row. The full strength of the structure is not reached until the grout (silicone in my case) is in place and dried which takes a few days.
