Stepped Glass – The Ultimate FAQ Guide

Do you know what stepped glass is? Or is this your first time hearing what it is? Should it sound familiar to you in a sense where you really don’t know where you heard it, don’t worry! In fact, many people don’t even know that there exists such a thing!

Today, we’ll be walking you through understanding what is stepped glass. We’ll go about the different functionalities of stepped glass, where you can use it and its applications, and many more!

So, when you’re finished reading this guide, you’ll be a master of stepped glass. Not only that, you’ll also know where you can find the best stepped glass manufacturer, too!

What is Stepped Glass?

Stepped glass, also known as offset glass or an insulated glass unit (IGU), is the glass that has either two (2) or three (3) layers of insulating glazed units.

Stepped glass

                         What’s stepped glass looks like?

It is labeled “stepped glass” is because the outer layers are larger than the one before it. Thus, creating a step-like figure or structure on the glass.

What Are in Spaces in Between Layers of Stepped Glass?


To help you understand it further, let us break the anatomy of stepped glass.

We’ll list down the parts and the composites of stepped glass, as well as what they’re for.

Toughened Glass or Outer/Exterior Glass

This is the glass that’s used to be on the outer-end. It’s the glass you’ll want to use to meet sunlight, air, rain, snow, or any other type of external substance.

Spacer or Space Bar

The spacer is the thing that separates and divides two (2) or three (3) of the glasses. Unlike regular spacers, spacers in stepped glass usually contain a type of hygroscopic material to prevent fogging.

Low E-Glass

Low-emissivity glass, low e-glass for short, is the type of glass you use in the second layer. What this does is it’ll keep ultraviolet rays that come through your glass at the minimum.

The low e-glass capability is thanks to the special coating that reduces heat gain and loss.

How Does an Insulating or a Stepped Glass Work?

The magic of stepped glass is still unknown to many, but when you know it, it’s a simple idea.

We know that stepped glass is “stepped” because it has many different layers, right? Well, the space between these layers is comprised of gas. More often than not, you’ll have krypton or argon in there for better and more effective insulation.

This gas is the one responsible for the process of insulation since they’re a lot denser than air, therefore restricting the activity of it passing through the glass.

Is Stepped Glass Expensive or Costly?

If you were to purchase stepped glass in retail rates and prices, it’ll be somewhere around $10 to $25 per square foot.

There are even some cases where it can reach up to $45, depending on the layers, the gas used, and overall the quality of the glass.

That rate is for insulated, thermopane, and thermal glasses.

Insulating glass or stepped glass flats or plates cost anywhere upwards of $25 up to $100.

Can You Print Color on Stepped Glass?

Yes, you can print color onto insulating or stepped glass if you deem it to be necessary.

Colored insulating or stepped glass

And how do you add color to glass? – You can actually use the traditional method of adding a mixture of metal powders or metal oxides to glass.

But, in modern times, screen printing is the one that’s considered the simplest and the easiest. You would also use this for applications and printing that requires a high volume of work.

In this method, you’ll have to use the following:

  • Ink
  • Mesh screen
  • Stencil

8mm stepped glass

When you have the ink ready, you want to spread it across the mesh screen using a squeegee. Then, you can also choose to use a stencil to block areas of the glass so that the ink could pass through.

After you finalize the colors you want, you would have to fire the ink so that it sticks fast to the glass.

What is the Common Size or Measurement of Stepped Glass?

Manufacturers consider thicknesses that range between 1/8” and 3/8” or 3 and 10 mm.

While this is the most common, you can specify a particular thickness or size of stepped glass depending on the business needs you have.

For instance, if you need it to use it as a type of roof, you can purchase it in larger sizes to save money because purchasing 10 different pieces of glass in almost the same sizes can cost twice compared to you purchasing it as one big part.

Is Offset Glass the Same as Stepped Glass?

Yes, offset glass is also stepped glass. The only reason why you’d recognize it as offset glass is because of the outside or the toughened glass is usually covered for aesthetic reasons.

Offset glass wherein the inner glass is slightly smaller in size compared to the outer one

So, don’t be confused when you encounter offset glass – it’s the same as insulating glass units (IGUs) or stepped glass.

Double-Glazed vs. Triple-Glazed Stepped Glass

Since IGUs or stepped glass can either be double-glazed or triple-glazed, which one should you choose?

Image of what a triple-glazed stepped glass is

A lot of people speculate that getting triple-glazed IGUs wouldn’t actually do anything more than what a double-glazed stepped glass can. When, in reality, you can use them for something different.

Let’s start by understanding that a double-glazed mirror is something that only has two (2) glasses and a triple-glazed mirror is something that has three (3).

For comparison purposes, let’s pretend that both the double-glazed and the triple-glazed glasses have the same spacers, the same gas, the same glass type, as well as attributes and characteristics.

Weight and Performance

In weight, double-glazed stepped glass obviously weighs less than that of the triple-glazed. Basically, what this means is that you’ll find it easier and simpler to install.

Triple-glazed stepped glass weighs more than double what double-glazed glass does.

Double-glazed stepped glass also gives a little bit more light than triple-glazed windows, while triple-glazed windows are better in filtering ultraviolet rays.

Thermal Insulation

Should you use it for your windows and roofs, the triple-glazed stepped glass will be the best and the most efficient in insulating.

You can find better results in filtering UV rays with triple-glazed glass than double-glazed.

Cost and Price

Of course, since double-glazed stepped glass performs less than triple-glazed, you can expect the price of the latter to be more expensive.

However, you would find the rates of triple-glazed stepped glass to have more value than that of the regular double-glazed.

Where Do You Usually Use Stepped Glass?

The best applications of IGUs or stepped glass are in the architectural or the engineering sector or industry.

You can find stepped glass in many different applications

Moreover, you would often find them in tropical countries to deflect heat and to keep the temperature indoors comfortable and convenient.

Besides those applications, a couple of other applications where you can find stepped glasses useful for include:

  • Factories to keep humidity and temperature
  • Entertainment centers
  • Conference rooms and meeting locations
  • Recording studios
  • Buildings and establishments (to hide frames)
  • And many more!

Overall, the point is simple – and it is to prove that insulated stepped glass isn’t only for the residential industry. You can actually make use of it in the industrial and commercial sectors, too!

What is the Purpose of Stepped Glass Being Stepped?

Many people think that the reason behind a stepped glass’s appearance is for aesthetic purposes only.

How the steps or layers of glass look like with its border

However, there are sources that say that the smaller the area is for the absorption of heat, the more focused it is. So, the farther and the smaller the glass, the more that it traps heat from entering or from escaping.

This can also be another reason for its physicality being like this.

What Are the Benefits Should You Choose to Use Stepped Glass?

Stepped glass can independently be placed in any situation

There actually are quite a few advantages of using insulated or stepped glass.

Below is a quick list for you to be aware of what these advantages are:

Conservation and Preservation of Energy

The first benefit or advantage of using stepped glass is that you’ll be able to conserve energy. The thermal insulation of stepped or offset glass can control the heat that comes in and that goes out.


Another benefit or advantage that you can get with stepped glass is that it’s a lot more reinforced, stronger, and more durable compared to regular glass.

Usually, IGUs are sealed, this what makes it difficult to break from its external side. Add the fact that it contains two (2) or three (3) layers of glass, it’ll be extremely challenging to damage or crack.

Insulation (Heat and Sound)

Since it has two (2) or three (3) glass panes in a stepped glass unit, you can expect it to provide better sound and heat insulation.

You can find it beneficial if you’re going to use the stepped glass in the industrial and the residential settings, where there are a lot of people as it can block out the sound circulating, as well as the heat that’s generated by the vehicles and the people.

Flexible and Versatile

The most common misconception that people have with stepped glass is that it needs to be float glass 100% of the time.

However, that isn’t true all the time. The only reason why people choose float glass is that it’s the cheapest and the most modest when it comes to the price and rate.

Should you have other types of glass in mind, you can use it, too!

  • Heat Strengthened Glass
  • Reflective Glass
  • Patterned Glass
  • Laminated Glass
  • Tinted or Stained Glass
  • Toughened Glass
  • Ceramic Printed Glass

Stepped glass is versatile – you can use whatever type of glass you have in your possession.

Other than these benefits, here are some of the lesser talked about:

  • More comfortable space (low humidity)
  • Reduced noise
  • Decreased levels of glare
  • Retaining of heat
  • Reduction of fading of the glass

While you may find these benefits to be almost perfect, you’ll experience a couple of drawbacks in using stepped glass, too.

What are the Drawbacks of Using Insulated or Stepped Glass?

Some of the most notable disadvantages of using stepped glass are:

Higher Initial Cost

One of the cons and disadvantages of using stepped glass is the fact that it’s priced more expensive and more costly than regular monolithic glass.

Many people see it as a burden, but if you look at it in the longer term, it’s practical and more economical than using traditional glass. But since we’re talking about the initial cost, it’s something that you need to consider too.

Not Repairable

Another drawback that stepped glass has is that it’s not repairable. So, when a piece gets broken, you need to replace the unit entirely.

Possible Leakage

Since only a spacer or a space bar separates the panes, you have to make sure that it’s sealed properly.

An improper seal can result in a possible leakage, which can be harmful to you (since it contains gas) and can let air escape. Furthermore, it can place the glass into condensation, which can damage the glass unit.

Cloudiness and Fogging

Last but not least is the chance that it can cloud and fog. Depending on the type of gas in between the steps, fogging can occur. So, it is imperative that you’re knowledgeable in terms of managing and handling it.

Due to the moisture in between, transparency can be reduced and decreased, which can therefore be the cause of cloudiness and fogging.

These are the drawbacks and the cons of using insulated or stepped glass for your establishment. You can consider the benefits more than the disadvantages that it has.

Insulated or Stepped Glass Specifications

For the specifications of these stepped glass units, it’ll depend on the product that’s manufactured by the supplier.

Images of stepped glasses stacked up against each other

However, there are specs and characteristics that are standard. They include:

  • Standard Thickness: 14 mm to 24 mm (commercial use)
  • Maximum Thickness: 50 mm
  • Maximum Size: 2440 mm x 3660 mm
  • Gas: Can be filled with Dry Air (Argon), Sulfur Hexafluoride (SF6), Krypton

When it comes to the glass type, you’re not just limited to one (1) type. As a matter of fact, you can utilize multiple types of glass, including frosted glass, clear glass, reflective glass, heat-strengthened glass, toughened glass, and so on.

These are some of the specifications that you can get if you choose stepped glass!

How Are Stepped Glass Units Tested?

You can’t just rely on the spacer that you see and how the other back-end of the glass looks. There are a couple of assessments and evaluations you can perform to ensure that it’s built properly.

NOTE: These tests are usually done within the manufacturing process. But, it’s still better if you know about these evaluations.

  • Absorption Test
  • Dew Point Test
  • Delta “T” Test
  • Moisture Vapor Contents Test
  • Ultra-Violet Ray (UV Ray) Test
  • Leakage Test

Since newer and more updated glasses are roaming the market, you’re not only limited to these evaluations and assessments.

What are the Different Types of Stepped Glass?

Insulated or stepped glass isn’t just limited to one (1) type. In fact, there are a few different types of stepped glasses in the market today.

Image of a low-E stepped glass unit

NOTE: More and more types of stepped glass are born in the market on a regular basis. So, don’t be confused when you find out that there are more than ten (10) already!

Dual-Seal Silicon IGU

You can consider this type of stepped glass to be the most modern-looking. What separates dual-seal silicon stepped glass is its durability and longevity.

It’s designed to withstand time and it’s considered to last longer than the traditional forms of stepped glass.

In addition to that, you can also expect it to have low levels of moisture penetration. This is responsible for the maintenance of the insulation capacity and property of the glass.

Low-E Stepped Glass

As we all know, this is the usual type of glass used in the second layer of the step – it’s what’s responsible for keeping ultraviolet (UV) rays from penetrating the glass, creating the hot and humid temperature within your space.

E-coating or emissivity coating is done via deposition of metal oxides. It’s also the procedure done to give a greenish tint on a glass surface.

FACT: Did you know that emissivity coatings can cut energy consumption by up to 50%? Moreover, it is the factor that makes energy conservation true.

Argon-Filled IGU

In a stepped glass, we know that argon is used as one of the gases enclosed by the spacer. This is because of the fact that argon is a gas that does not have any odor, color, and it’s a non-toxic type of gas.

Therefore, you can use it to increase and heighten the performance of the stepped glass in restricting heat to enter or exit the pane.

Using Laminated Glass to Replace Stepped Glass

While laminated glass isn’t exactly a type of IGU or stepped glass, you can consider it as an alternative to them. Besides, their main function is to keep a structure’s stature straight and strong.

Akin to stepped glass, laminated glass isn’t singular; it’s actually comprised of multiple glass sheets pasted together.

Unlike stepped glass, though, these sheets are combined and mixed with an interlayer of plastic. While it’s not as effective as the stepped glass that we know, it’s actually cheaper, more affordable, and also easy-to-work-with.

Can Stepped Glass Be Tempered?

Yes! As a matter of fact, before they’re even built or assembled, they have already undergone tempering; it’s ready and it’s just waiting to be built and assembled.

Example of a tempered glass being used as insulating or stepped glass

The tempering is done to make sure that it’s safe from regular impact; that it has high levels of insulating properties, and that it has strength and durability.

It’s basically a reinforcing or a strengthening type of procedure.
