KINGSTAR GLASS
Bronze Float Glass | Body-Tinted Solar Control Architectural Glass from KINGSTAR BUILDING GLASS
KINGSTAR BUILDING GLASS Bronze Float Glass is a premium body-tinted architectural glass manufactured by incorporating carefully selected metal oxides into the glass batch during the float production process. The result is a uniform, distinctive bronze color that permeates the entire glass thickness—with color intensity that naturally deepens as thickness increases. Bronze float glass offers excellent solar control performance while delivering a sophisticated warm aesthetic that harmonizes with b
What is Bronze Float Glass?
Bronze float glass is a body-tinted soda-lime silicate glass produced by adding metal oxides to the glass batch during the float manufacturing process. Unlike surface-coated glass, the color is integral to the entire glass thickness—ensuring that the aesthetic and solar control properties remain consistent even after cutting, edging, or processing. The bronze tint provides effective solar control and glare reduction while delivering a distinctive warm aesthetic that is highly prized by architects and designers.
The glass is produced in compliance with EN 572-1, EN 572-2, and EN 572-9 standards, and is CE-marked for use in building applications. KINGSTAR BUILDING GLASS bronze float glass is available in a full range of thicknesses and can be processed into tempered glass, laminated glass, insulating glass units, bent glass, coated glass, and mirrors.

Frequently Asked Questions (FAQ)
Q1: What is the SHGC and visible light transmittance of bronze float glass?
A: For bronze float glass, performance varies by thickness. 4mm bronze glass provides 63% VLT with SHGC of 0.70; 6mm provides 50-53% VLT with SHGC of 0.60-0.63; 8mm provides 41-43% VLT with SHGC of 0.53-0.61; 10mm provides 37% VLT with SHGC of 0.52; and 12mm provides 27% VLT with SHGC of 0.46. As thickness increases, color intensity deepens and both VLT and SHGC decrease. The visible light reflectance ranges from 5% to 7% depending on thickness.
Q2: How does bronze float glass compare to other tinted glass options?
A: Bronze float glass delivers a warm aesthetic with effective solar control—offering VLT of 50-53% and SHGC of 0.60-0.63 for 6mm glass. By comparison, grey float glass provides 44% VLT with SHGC of 0.58, green float glass provides 77% VLT with SHGC of 0.61, and dark grey provides only 9% VLT with SHGC of 0.29. Bronze offers a unique balance: superior solar control compared to clear glass, with a warm aesthetic that grey and green tints cannot match. Bronze is well known as a key product in the furniture world and is widely used in several types of secondary processing, especially mirrors and acid-etched glass.
Q3: Can bronze float glass be tempered or combined with other glass products?
A: Yes. KINGSTAR BUILDING GLASS bronze float glass is fully compatible with tempering (EN 12150), laminating (EN ISO 12543), and insulating glass unit fabrication. It can also be heat-strengthened, bent, coated, silvered, sandblasted, or acid-etched. When combined with Low-E coatings or used in insulating glass units with argon gas fills, bronze float glass can achieve significantly improved thermal performance while maintaining its distinctive warm aesthetic and solar control properties.
Tinted Glass is produced by the float process with the addition of small
quantities of metaloxides to color the normal clear glass mix. This coloration is achieved
through adding metaloxides at the smelting stage. Addition of color does not affect the
basic properties of the glass, even though visible light reflectance will be slightly higher
than clear glass.
tinted float glass can reduce transmission of the sun's harmful rays by up to
80% thus minimizing fading to interior furnishings .
The comprehensive range of soft natural colors compliments and harmonizes with
modern building materials to provide an exciting and different look to new or existing buildings .
Could be easily cut, bent, insulated, lami nated, lacquered, coated, tempered or heat
strengthened and in addition can be silk-screened.
