Wallington High School In Wallington, NJ Gets An Upgrade

In the Summer of 2016, Wallington High School located in Wallington, NJ was undergoing some renovations. The small Bergen County town had planned on doing some useful and much needed upgrades/renovations to the Jr/Sr High School. The school district’s architect on the job, Blase Weimer of The Architects Alliance, had given us a call about some glass block windows for part of the renovation project, specifically a stairway they were redoing. Not only did they want more light inside, but they didn’t want to sacrifice security or safety; it is a school after all. We told them not to worry and that we could (and did) fabricate for them 12 glass block windows to be easily installed on the jobsite when the time came.

As you can see, the glass block panels we prefabricated for them use the PC Vue glass blocks and were assembled with mortar. Most of the time the glass blocks people want to sue are somewhat distorted to add some privacy. The amount of light getting in is at a maximum when using the Vue glass blocks as opposed to the much more common Decora/Wavy style. These glass block panels were built frameless as opposed to using a white vinyl frame so the contractors on the job could seal them with a frame of their own as you can see above. Not only do the glass block panels let the most light in while being secure, they are also much more energy efficient when compared to regular single-pane windows that are typically used in schools.



School officials put this renovation project in works a few years back with the objectives being to replace the original roof which was deemed to have “outlived its usefulness” by Weimer, get new windows, fix masonry leaks in the foundation, safety upgrades and some re-painting. The renovation project is completed now and we were happy to be a part of it. The glass block windows we made came out excellent and the jobsite contractors did a wonderful job installing them.

What To Do If Your Plans/Specs Call For Vistabrik

In light of Pittsburgh Corning’s closing, there have been many changes in the glass block industry. Among the many glass block styles that are no longer made, there are also a number of glass blocks themselves no longer made. There are alternatives available from other manufacturers to keep homeowners and contractors from completely freaking out when a plan/specs calls for the use of Vistabrik, a solid glass block make by PC. On the other hand, for the glass blocks that aren’t available even from other manufacturers it often leaves people asking “What am I supposed to do now?”. Pittsburgh Corning’s Vistabrik solid glass block was a major part of the commercial glass block industry. It’s popularity stemmed from its high fire-rating and its durability all while being completely transparent for light transmission. There have been many instances over the past few months where I’ve had to help people figure out what to do when their project calls for Vistabrik. In this article I’ll go over some fire-rated glass block alternatives and a solid glass brick alternative to use in place of Vistabrik.

If you’re familiar with glass blocks you know what the Decora pattern looks like. The first and most important difference between Vistabrik and Decora glass blocks is this: Vistabriks are solid glass blocks while the Decora and every other pattern are hollow glass blocks. Even if you’re unfamiliar with glass blocks you’ve probably seen the Decora pattern somewhere since it’s the most popular style. Decora Thickset glass blocks (the fire-rated version of glass blocks) have fire-ratings of 60 and a 90 minutes. The 60 minute fire rating meets the requirement of most fire-rating applications, where the 90 minute fire-rating is more for a zero lot-line application. If you’re in need of a closer substitute to the solid glass block, then there is also Vue glass blocks.

These specific “Thickset” glass blocks have thicker faces than normal glass blocks to give them their fire-ratings. Vue Thickset glass blocks also come in 60 and 90 minute fire-rated. The difference between Vue and Decora is simply the pattern. The Decora glass block is slightly wavy and slightly distorted where the Vue glass blocks are completely transparent, like the Vistabrik solid glass blocks. The Thickset glass blocks are viable fire-rated substitutes for solid glass blocks that are no longer made.

If your project calls for Vistabriks but not for a fire-rated application, then there may be a another product for you. A solid glass block that is made by Seves is called a Vetropieno. These are smaller than other glass blocks and shaped most like a real brick. They come in 4 colors: Clear, Blue, Amber and Black and come in two sizes: square (4.5″x 4.5″x 2″) and rectangle (4.5″x 9″x 2″). These Vetropieno glass bricks can be used just about anywhere and are the perfect substitution for a plan that specified Vistabrik for its brick shape.

Often, switching between Vistabrik and these Thickset blocks above is barely a problem and we wish help those who feel their project is dead in the water. Feel free to give us a call if you want some more information or to discuss your project and how thee alternatives can help you.

The Glass Block Possibilities Using Seves Glass Blocks

With the closing of Pittsburgh Corning earlier this year, a lot of the glass block industry was changed. The ripple effects of their exit from the industry are still being felt, but it isn’t the end of glass blocks. Seves Glass Block, a division of The Seves Group, a well-known company that manufactures glass and composite insulators for electrical systems, as well as glass block, has been the go-to in the glass block industry all over Europe. The Seves Group is based out of Italy and their market reaches all the way to the Western hemisphere. Seves Glass Block offers many different colored glass blocks, 3-D glass blocks, trapezoidal glass blocks and more. Their glass block products have been used all across the world which can be seen in the videos on our YouTube channel.

Seves Glass Block offers many different types of glass blocks, not only in different styles but also different little tweaks among styles. For example, they offer what is called “satin” that can be on one or both faces of the blocks. Their selection of color blocks come in both a wavy style and a completely see-through style simply named Clearview. The different combinations of glass blocks that is offered by Seves is something that is unmatched. An international trade show for construction materials and building solutions called Construtec took place in Madrid, Spain in October 2016. Seves Glass Block had a beautiful exhibit that highlighted much of what they offer used in different ways. In the next video below you can see the video highlight 3-D glass blocks, their solid glass bricks called Vetropienos, trapezoidal glass blocks, the Clearview in both color and non-color, the wavy style in both color and non-color, color glass blocks with the satin finish, circular glass blocks and much more. It’s really a cool video with lots of glass block uses in just a few minutes and limited space!
