Building a Glass Block Wall

If you have been considering using glass block as a building material in a wall, installing glass block is easier than you may think. Here are some facts and ideas to help you get started.


Considerations, Myths and Facts about building a Glass Block Wall

You usually do not need a special support under the wall, unless there is a problem with the floor already standard subfloor framing is usually enough to support the block wall.

The walls can be prefabricated. Straight prefabricated walls make the project easier and less costly to perform. Rounded walls are generally built at the job site.

The walls are sturdy. Most block walls are tied into surrounding wall(s) using panel anchors or vinyl stack anchors every 3rd course (or 24″). Panel reinforcing or horizontal vinyl stack pieces provide additional stability.

With the development of glass blocks with angles, corners, and finished ends there is usually no need to use dissimilar materials to finish the sides and tops of your project.

Why Vistabrik Is A Great Idea In A Commercial Setting

A majority of commercial building structures have regular, single pane windows with a frame usually of aluminum or vinyl. They are very common among commercial structures due to their inexpensiveness and the fact that they are easy to get a hold of. However, single pane glass windows can easily break and need to be constantly maintained which in turn costs the commercial entity money to do so. Choosing to get rid of single pane windows and go with glass bricks, specifically Vistabrik, is the better choice with many benefits.

Vistabrik is a solid 3″ thick piece of glass that is as identical as it gets to a regular brick, but obviously glass. These solid bricks don’t diminish the the amount of light coming in either and in fact let in more light that further brightens up the room. Vistabriks are also a great choice for a building structure in an area that leaves it vulnerable to damages. Vistabrik has inherent characteristics that make them graffiti resistant, flame resistant sot can hold up with fire codes and they are also bullet proof. These offer the best protection from almost anything a commercial building will encounter.

Vistabrik solid glass blocks also have noise reduction characteristics which single pane windows do not. This will help keep an excess of noise outside and not bothering your business. These solid glass bricks in the end save you money from not needing to continually pay for maintenance costs as you would with regular windows as well as a huge increase in energy efficiency. Vistabrik blocks offer much more insulation than single pane glass windows which will lower heating and cooling bills. Vistabrik solid glass bricks are commonly used in schools, public transportation stations like trains, prison systems and even airports and it continues to become increasingly popular.

Fire Rated Glass Block In a Zero-Lot Line

Having Fire Rated Glass Block installed may be a requirement depending on where they will be going or it can be for personal reasons. When houses or buildings are very close together, that is what’s considered a zero-lot line. When structures are in a zero-lot line, the danger and risk of fire spreading from structure to structure is much higher. There are ways to help limit the risk of catching a fire from a structure in very close proximity. One great way to consider is to get Fire Rated Glass Blocks.

Fire Rated Glass Blocks come in fire ratings of 45, 60 and 90. Along with traditional fire rated glass block, there is also Vistabrik, which is 3″ of solid glass block and the toughest product. There is a great variety of styles of block available that are fire resistant and also a few different sizes to choose from. Some fire codes require a fire resistant wall or window when the structures are close. Fire Rated Glass Block will give you ample protection when such a scenario is present. Fire Rated Glass Block is also resistant to graffiti and has added noise resistance. Vistabrik blocks have both of those qualities as well, plus the added benefit of being bulletproof for the highest level of protection.
