Curious About Invisible Shield® Pro 15 Nano Tech Coating? 

Quick Take: Every Glass Office Chair Mat by Vitrazza is protected with Invisible Shield® Pro 15 Nano Tech Coating. This professional-grade treatment helps resist fine scratches and etching, repels water and surface contaminants, and makes the glass easier to clean. It does not make the Glass Chair Mat unusually slick or cause an office chair to roll faster. Smooth chair movement comes from the flat, rigid tempered glass, while the coating helps protect its appearance. 

If you have been researching Glass Chair Mats, you may have come across the term Invisible Shield® Pro 15 Nano Tech Coating. 

It is one of several details that distinguish a Vitrazza Glass Chair Mat, but it is also easy to misunderstand. Some people assume it is simply a scratch-resistant finish. Others wonder whether a coating makes the glass slippery, especially when shoes are wet, or whether it is responsible for the smooth way an office chair rolls across the surface. 

Invisible Shield® Pro 15 helps protect the glass, improve cleanability, and preserve its appearance. The smooth rolling experience comes from the strength and rigidity of the Glass Chair Mat itself. 

Here is what the coating does, what it does not do, and how it works alongside the other features that make a Vitrazza Glass Chair Mat a lasting office upgrade.

 

What Is Invisible Shield® Pro 15 Nano Tech Coating? 

Invisible Shield® Pro 15 Nano Tech Coating is a professional-grade protective treatment applied to every Vitrazza Glass Chair Mat. 

It creates an invisible barrier on the glass that helps repel water, soil, grime, fingerprints, and other everyday surface contaminants. It also helps the glass resist fine scratches and etching that could otherwise affect its appearance over time. 

The treatment does not visibly change the glass. A Vitrazza Glass Chair Mat remains clear, polished, and designed to showcase the flooring underneath. What changes is how the surface responds to water, dirt, routine cleaning, and everyday contact.

 

Why Does Vitrazza Apply a Protective Coating to Tempered Glass? 

Tempered glass is already exceptionally strong, but strength and surface appearance are two different considerations. 

The 1/4-inch tempered safety glass provides the structural durability needed to support an office chair without denting, curling, or developing wheel tracks. Invisible Shield® Pro 15 helps protect the visual appeal of that glass through years of daily use. 

A Glass Chair Mat is not meant to be a temporary accessory. It becomes a highly visible part of the office, so its long-term appearance matters. That is why Vitrazza combines durable tempered glass with a protective surface treatment rather than relying on the glass alone.

 

What Does Invisible Shield® Pro 15 Actually Do? 

It Helps Resist Fine Scratches and Etching 

Chair wheels, shoes, dust, grit, and small particles come into contact with a chair mat every day. Invisible Shield® Pro 15 adds another level of surface protection by helping resist fine scratches and etching. This does not make the glass completely scratch-proof, but it helps preserve its clarity and polished appearance through normal office use. 

That distinction matters. No responsible manufacturer should claim that a glass surface can never be scratched. The purpose of the coating is to improve resistance to the fine surface blemishes that can gradually affect untreated glass.

 

It Repels Water 

Untreated glass attracts water. Instead of remaining in isolated droplets, moisture tends to spread across the surface. Invisible Shield® Pro 15 changes that behavior by encouraging water to bead. 

Those droplets are easier to see and wipe away than a thin film spread across the glass. This makes spills and moisture easier to manage because the water remains concentrated in droplets rather than spreading across the surface.

 

It Makes the Glass Easier to Clean 

A Glass Chair Mat naturally collects some of the same things found on any frequently used floor surface: 

• Dust 
• Pet hair 
• Shoe marks 
• Fingerprints 
• Food crumbs 
• Coffee and other spills 

Because water and common surface contaminants are less likely to spread and cling to the treated glass, routine cleaning is quick and simple. For the best results, use a microfiber cloth and Repel® Glass & Surface Cleaner. Its dual-action formula cleans to a streak-free shine while helping maintain the Invisible Shield® Pro 15 coating and repel water, soil, grime, and fingerprints.

 

It Helps Preserve the Appearance of the Glass 

The value of the coating extends beyond easier cleanup after a spill. By helping resist fine scratches, etching, grime, and surface buildup, Invisible Shield® Pro 15 supports the long-term clarity of a Vitrazza Glass Chair Mat. It helps the glass continue looking polished and refined instead of gradually taking on the worn appearance common with many plastic chair mats.

 

Does Invisible Shield® Pro 15 Make a Glass Chair Mat Slippery? 

No. Invisible Shield® Pro 15 is not applied to create a slick or unusually slippery surface. 

One of the most common concerns about any glass floor product is what happens when someone steps on it with wet shoes. Because glass looks smooth, it is easy to assume that moisture will automatically make it dangerously slippery. 

The way water behaves on the surface is important. On untreated glass, water is attracted to the surface and tends to spread outward, creating a more continuous film between the glass and the bottom of a shoe. Invisible Shield® Pro 15 helps prevent that spreading by causing water to bead into separate droplets instead. 

By reducing the continuous layer of moisture across the glass, the coating helps reduce slipperiness when water is present rather than increasing it. A Vitrazza Glass Chair Mat is therefore not made slick by the coating. Water from shoes should not pose a problem during normal use. 

As with any hard flooring surface, visible spills should still be wiped up promptly. No surface should be treated as completely slip-proof when a large amount of liquid is present.

 

Does the Coating Make an Office Chair Roll Faster? 

No. Invisible Shield® Pro 15 protects the surface, but it is not what creates the smooth rolling experience. 

A chair rolls easily on a Vitrazza Glass Chair Mat because tempered glass remains: 

• Flat 
• Rigid 
• Stable 
• Free from dents 
• Free from wheel tracks 
• Resistant to compression under normal office use 

Many plastic chair mats gradually develop depressions beneath the chair wheels. The casters settle into those ruts, requiring additional effort each time the user wants to move. 

Tempered glass does not respond that way. It remains consistently flat, allowing chair wheels to travel smoothly across the surface without repeatedly climbing out of soft spots or grooves. The coating protects the glass. The rigidity of the glass supports chair mobility.

Is Invisible Shield® Pro 15 a Wax or Temporary Polish? 

No. Invisible Shield® Pro 15 is not a household wax or temporary shine product. It is applied as a professional-grade protective treatment before the Glass Chair Mat reaches the customer. It does not need to be polished onto the glass every few weeks or reapplied as part of normal routine maintenance. 

Proper cleaning helps maintain the treated surface. That is one reason Vitrazza recommends Repel® Glass & Surface Cleaner, which is formulated to clean the Glass Chair Mat while maintaining the Invisible Shield® Pro 15 protection.

 

Does Invisible Shield® Pro 15 Prevent Every Scratch? 

No surface treatment can make glass completely scratch-proof. Invisible Shield® Pro 15 is designed to help resist fine scratches and etching. It reduces the likelihood of small surface blemishes caused by everyday use, but sharp objects, abrasive debris, or improper cleaning materials may still damage glass. 

To protect the surface: 

• Remove gritty debris before wiping. 
• Use a clean microfiber cloth. 
• Avoid abrasive scrubbers. 
• Do not drag sharp metal objects across the mat. 
• Use a cleaner appropriate for treated glass. 

The coating increases surface protection; it does not make the Glass Chair Mat indestructible.

 

Nano Tech Coating Is Only One Part of the Vitrazza Difference 

Invisible Shield® Pro 15 is an important part of the Vitrazza experience, but it's only one of several engineering decisions that contribute to the performance and longevity of every Glass Chair Mat. Glass thickness, tempering, edge design, stability, and surface protection all work together to create a product built for years of everyday use.

 

1/4-Inch Tempered Safety Glass 

Every Vitrazza Glass Chair Mat is made from solid 1/4-inch tempered safety glass tested to support more than 1,000 pounds. 

While some lower-cost Glass Chair Mats are manufactured using thinner 4 mm glass, Vitrazza uses thicker 6 mm tempered glass to provide greater rigidity and long-term durability. The additional thickness helps the Glass Chair Mat resist flexing under load while providing the solid, stable rolling surface people expect from a premium Glass Chair Mat.

Vitrazza Glass Chair Mats are manufactured using glass certified by the Safety Glazing Certification Council and tested to meet ANSI Z97.1 safety-glazing standards. These independent standards verify that the glass has been properly tempered and meets established requirements for strength and safe breakage behavior.

Tempering makes glass significantly stronger than ordinary annealed glass of the same thickness. The rigid construction prevents the mat from denting or developing the wheel ruts that commonly interfere with movement on plastic chair mats. 

The strength comes from the glass. The surface protection comes from Invisible Shield® Pro 15. Together, they support both long-term function and appearance.

Furniture-Quality Mini-Bevel Edges 

Every Vitrazza Glass Chair Mat is finished with polished, furniture-quality edges and a subtle Mini-Bevel. 

Not all beveled edges are designed the same way. 

An extra-wide tapered bevel creates a long ramp by progressively thinning the glass toward the outer edge. Although that profile may look appealing, it also leaves less glass at the perimeter-the area most vulnerable to edge impact. 

Vitrazza takes a more balanced approach. 

The Mini-Bevel uses a slight chamfer of approximately 1/8 inch to soften the transition and make it easy to roll a chair on and off the mat. At the same time, it avoids unnecessarily thinning the edge of the Glass Chair Mat. 

The result is: 

• A refined, furniture-quality appearance 
• A smooth, polished transition at the edge 
• Protection against the nicks associated with rough square edges 
• Greater glass thickness near the perimeter than an extra-wide tapered bevel 

Vitrazza's edge is not simply flat-polished. The Mini-Bevel is an intentional design choice that balances chair movement, visual refinement, and edge durability.

 

Stabil-a-dot Bumper System ™

Every Vitrazza Glass Chair Mat includes the Stabil-a-dot Bumper System™, a set of clear rubber bumpers designed to keep the mat firmly positioned on a variety of flooring types.

Different bumper sizes are included for: 

• Hard flooring 
• Standard carpet 
• High-pile or shag-style carpet 

The clear rubber bumpers help keep the Glass Chair Mat securely in place on virtually any flooring surface. Whether on carpet or hard floors, they provide the grip needed to help prevent the mat from shifting during everyday use. They also provide slight clearance between the Glass Chair Mat and the floor so the surface underneath can breathe without trapping moisture. 

The office chair moves smoothly across the top. The Glass Chair Mat remains stable underneath.

 

Two Glass Clarity Options 

A Glass Chair Mat protects the floor without hiding it, but the glass composition can affect how clearly flooring colors and textures show through. 

Vitrazza offers two clarity options: 

Chiaro™ Standard Clear Glass provides a classic clear appearance with the slight green undertone commonly associated with standard glass. 

Luminoso™ Low Iron Ultra Clear Glass contains significantly less iron, creating a brighter and more color-neutral appearance. It is especially effective over light flooring or in spaces where maintaining true floor color is a design priority. 

Both options receive the same Invisible Shield® Pro 15 protection.

 

Transferable Lifetime Warranty 

Vitrazza Glass Chair Mats are built as lasting products rather than disposable office accessories.

Vitrazza has built a reputation for delivering quality products and standing by those products with a satisfaction guarantee, meaning if you’re not completely excited to eliminate plastic chair mats from your life, we’ll give you a full refund and provide a pre-paid shipping label for you to return your Glass Chair Mat to us. 

We are so confident in our Glass Chair Mats that each one comes with a Transferable Lifetime Warranty that covers and defects or design flaws that would cause it to break.

 

Why Doesn't Every Glass Chair Mat Include Nano Tech Coating? 

Glass Chair Mats can look similar in product photos while differing significantly in their finishing processes. Some manufacturers rely on tempered glass alone. Others may offer basic polishing or make broad claims about scratch resistance without identifying a specific protective treatment. 

Vitrazza applies Invisible Shield® Pro 15 to every Glass Chair Mat as a standard feature. It is part of a broader belief that a long-lasting product should not merely remain functional. It should continue looking beautiful and remain easy to care for throughout its life. 

The coating is one of several details that may be invisible at first glance but become meaningful over years of ownership.

 

Why the Details Matter 

A chair mat may seem like a simple product: a flat surface placed beneath an office chair. 

But the daily experience depends on details that are easy to overlook: 

• Whether the surface dents 
• Whether chair wheels become trapped in ruts 
• Whether the glass is easy to clean 
• Whether water spreads or beads 
• Whether the perimeter retains its strength 
• Whether the mat remains stable on the floor 
• Whether the flooring underneath remains visible 
• Whether the product is supported for its lifetime 

Invisible Shield® Pro 15 Nano Tech Coating does not replace the need for strong tempered glass or thoughtful product design. It complements them. 

The glass provides the strength and smooth rolling surface. The Mini-Bevel refines and protects the edge. The Stabil-a-dot Bumper System™ keeps the mat in place. Invisible Shield® Pro 15 helps protect the clarity and appearance of the surface. 

Together, those details help create a Glass Chair Mat designed to perform beautifully for years.
