Groglass coating technology

Our technology

Honoring the past shaping the future.

For more than 20 years, Groglass has been transforming the way the world experiences glass and acrylic. Our innovative coatings turn ordinary surfaces into extraordinary works of art.

Greatness starts with the right foundation

The journey begins with selecting the purest base materials — from low-iron glass for true color clarity to premium acrylic for lasting durability. Because exceptional coatings start with exceptional surfaces.

  • Precision at the atomic level

    Just as stars are born in the silent void of the cosmos, our most advanced surfaces are shaped inside our vertical vacuum coater. There, we manipulate light at an atomic level, transforming pure substrates into high-performance products.

    • Vertical orientation

      By processing glass upright, we ensure that microscopic particles fall past the surface, resulting in a flawless finish.

    • Single step process

      We coat both sides of the substrate simultaneously, ensuring perfect optical symmetry and maximum efficiency.

    • Surface integrity

      Our system eliminates direct contact with the glass surface, keeping the substrate in its most pristine state from start to finish.

  • Engineering the behavior of light

    Light behaves as a wave, and our technology manipulates those waves with absolute precision — maximizing transparency while eliminating unwanted reflections.

    • AR COATING: How we make glass invisible

      Our coating works exactly like noise-canceling headphones, but for your eyes. We engineer coatings nearly 400 times thinner than a human hair that create an “anti-reflection” wave, canceling glare from the surface and making reflections disappear.

    • HR COATING: How we turn glass into mirrors

      Using the same accuracy, we align light waves to reinforce each other rather than cancel out. This allows us to create high-performance mirrors and semi-transparent surfaces where light is intentionally reflected and directed to specific technical requirements.

  • The science of protection

    Light does more than reveal the world; high-energy photons can also destroy it. As wavelengths shorten, they can break the chemical bonds holding pigments and materials together. We call this the “silent eraser” because the damage is permanent and often invisible until it is too late.

    • How we transform glass to UV shield

      Our specialized coatings block up to 100% of harmful UV radiation. By preventing bond-breaking at the atomic level, they help preserve vibrant colors and structural integrity for decades.

  • Our signature is quality

    To ensure visual perfection, every single sheet undergoes a systematic quality inspection upon exiting the coater. This automated process is reinforced by detailed "close tests" performed on every 10th sheet. This multi-stage system helps us ensure quality as our signature.
