Understanding the Marks of Quality: The Certified Glass in Every Yoowindows Door and Window

At Yoowindows, we believe that excellence lies in the details. From the sleek profile of our aluminium frames to the seamless operation of our hardware, every component is chosen with precision and purpose. But one of the most critical elements of any window or door is the one you look through: the glass.

Today, we’re pulling back the curtain on the certified glass we use, explaining what those little codes on the label truly mean for your comfort, safety, and investment.

A Closer Look at Our Certified Glass

The stamp on our glass isn't just a manufacturer's mark—it's a badge of certification and quality. Let's break down the key standards you'll find, like the ones shown in the image:

  • AS/NZS 2208:2016 & AS/NZS 4666:
    These are the cornerstone Australian and New Zealand Standards for glazing in buildings. Compliance with AS/NZS 2208 ensures the glass is fit for its purpose, covering aspects like optical quality, and freedom from unacceptable flaws. AS/NZS 4666 relates to the quality and durability of organic coatings on glass (like certain types of tinting or low-emissivity coatings). Using glass that meets these standards is non-negotiable for us; it’s our commitment to delivering products that are not only beautiful but also reliable, durable, and built to last in our unique climate conditions.
  • AS/NZS 4666:
    This standard specifically addresses the quality requirements for organic coatings applied to glass. It ensures that any coated glass we use maintains its performance and appearance over time, resisting degradation from environmental factors.
  • SMK 40795:
    This is a unique identifier from our glass supplier. It represents a specific product line that has undergone rigorous testing and quality control to meet the demanding standards we require. It’s our way of tracing quality back to its source.
  • TULLIAN CLASS:
    This designation points to the specific performance characteristics of the glass, often relating to its safety rating. "Tullian" typically indicates a type of laminated safety glass. This means the glass is constructed from two or more layers bonded together with a tough interlayer. In the unlikely event of breakage, this interlayer holds the glass fragments together, dramatically reducing the risk of injury from sharp edges and helping to maintain the integrity of the building envelope.

Why This Matters for Your Home or Building

Choosing Yoowindows means you are getting more than just a window. You are investing in a product that embodies:

  1. Uncompromised Safety: The use of certified safety glass, like laminated "Tullian Class" glass, is crucial, especially in large panels, doors, and areas where impact is possible. It protects your family and property.
  2. Guaranteed Performance: Adherence to AS/NZS standards means the glass will perform as expected in terms of thermal efficiency, noise reduction, and structural resilience, contributing to lower energy bills and a more comfortable living environment.
  3. Total Peace of Mind: These certifications are your assurance that every component has been independently verified. We don’t cut corners, so you can be confident in the quality and longevity of your installation.

At Yoowindows, we are transparent about the materials we use because we are proud of them. The certified glass in every one of our aluminium windows and doors is a silent promise—a promise of quality, security, and a clearer view to the world outside.
