Decorative Patterned Glass ndash The Perfect Solution for Adding Style and Functionality to Your Interior Design Project

​​Decorative Patterned Glass – Technical Specifications & Design Guide​​

Patterned glass is a translucent decorative glass manufactured by passing molten glass through patterned rollers to create permanent textured surfaces. This specialty glass combines aesthetic appeal with functional light diffusion properties.

​​Manufacturing Process & Technical Specifications​​

1. ​​Production Method:​​

   • Roller-pressed float glass process (continuous ribbon)

   • Pattern embossed while glass is in semi-molten state (≈900°C)

   • Annealed for stress relief (not temperable in patterned state)

2. ​​Standard Specifications:​​

   • ​​Thickness:​​ 3mm, 4mm, 5mm, 6mm (±0.2mm tolerance)

   • ​​Pattern Depth:​​ 0.1mm to 1.2mm (varies by design)

   • ​​Light Transmission:​​ 50-85% (depends on pattern density)

   • ​​Max Sheet Size:​​ 3300mm × 2140mm (standard production)

3. ​​Material Composition:​​

   • Soda-lime-silica base glass

   • Optional low-iron formulation for higher clarity

​​Pattern Classification System​​

​​Performance Characteristics​​

1. ​​Optical Properties:​​

   • Diffuses light evenly (haze 60-90%)

   • Reduces glare while maintaining brightness

2. ​​Structural Properties:​​

   • Can be laminated for safety applications

   • Post-processing options:

     • Sandblasting (additional texture)

     • Acid-etching (smoother finish)

     • Ceramic frit printing (color patterns)

3. ​​Thermal Behavior:​​

   • Coefficient of expansion: 9×10⁻⁶/°C

   • Annealed only - cannot be heat-strengthened

​​Industry Standards Compliance​​

• ​​EN 572-5​​ (European patterned glass standard)

• ​​ASTM C1036​​ (US specification for flat glass)

• ​​AS/NZS 2208​​ (Australian safety glazing)

• ​​GB 15763.2​​ (Chinese safety standards)

​​Advanced Applications​​

1. ​​Smart Glass Integration:​​

   • PDLC film lamination for switchable privacy

   • Electrochromic interlayers

2. ​​Acoustic Performance:​​

   • Laminated versions achieve STC 35-42

3. ​​UV Control:​​

   • Optional UV-blocking interlayers (blocks 99% UV)

​​Selection Guide​​

​​Maintenance Protocols​​

• Clean with pH-neutral detergents

• Avoid abrasive tools on textured surfaces

• Special considerations for:

  • Exterior applications (more frequent cleaning)

  • Food service areas (antimicrobial coatings)
