FAQ: Professional FAQ on Ultra Clear Glass

Q1: What material composition sets ultra clear glass apart?

A: The key is ultra-low iron content (Fe₂O₃ ≤ 120ppm), achieved by selecting purified silica sand. This nearly eliminates the greenish hue found in standard float glass.

Q2: Which international certifications does your clear float glass meet?

A: Our glass is certified to ISO 9001:2015 (quality management), ANSI Z97.1 (safety glazing), and is compliant with EN12150 (tempered), ASTM C1036 (quality standards), and RoHS environmental directives.

Q3: Can you explain what "light transmittance" and "color rendering index" mean in glass selection?

A: Light transmittance (LT) is the % of visible light that passes through. Color Rendering Index (CRI) measures color accuracy as seen through glass—high CRI (≥97%) ensures true color perception, essential in display and daylighting applications.

Q4: What defines "ultra clear tempered glass," and when is it used?

A: It’s ultra clear glass heat-treated for 4-5x higher strength, required in safety glazing (showers, facades, balustrades) to meet ANSI Z97.1 and EN12150 break safety standards.

Q5: What is your maximum glass sheet size and dimensional tolerance?

A: Up to 3300x6000mm; tolerance typically ±0.2mm on length/width, ≤0.1mm/m² for flatness, after CNC edge finishing.

Q6: What installation standards or best practices apply to ultra clear glass?

A: Always align with ASTM C1048 (installation), use proper gasket/sealant compatible with low iron glass, and support edges fully to prevent spontaneous breakage, especially for large area applications.

Q7: Is the product suitable for chemical, petrochemical, or corrosive environments?

A: Yes; ultra clear float glass is highly resistant to acids/alkalis (except HF acid), making it ideal for industrial viewports in refineries, laboratories, desalination plants, and corrosive process lines.
