Bronze Glass: warm tone, cooler interiors

I’ve walked more job sites than I can count, and one material keeps cropping up on façades that want style without glare: tinted glass. Our Bronze Glass adds that quiet, light-brown warmth architects keep asking for—subtle, not shouty. It softens sunlight, calms lobbies, and frankly makes late-afternoon meetings a little kinder on the eyes.

What’s trending (and why it matters)

Across North America and the Gulf, demand for tinted glass with baked-in solar control is rising—less fiddly than films, more durable than on-site coatings. Bronze tones sit in a sweet spot: warm color rendering, privacy in broad daylight, and a SHGC that helps beat energy targets without turning a building into a cave. Many customers say the lobby looks “finished” even before the furniture arrives.

Technical snapshot

Substrate: soda‑lime float glass tinted with metal oxides during the melt. Available from ShottGlass in standard and custom cuts, produced in Shahe City, Xingtai (North Second Row, East Side of Dadong Logistics).

Note: IGU performance improves SHGC/U-factor; ask for project-specific simulation (EN 410 / ISO 9050).

How it’s made and tested

• Materials: high-clarity silica, soda ash, limestone; bronze tint from controlled metal-oxide dosing.
• Process flow: float forming → online tint → annealed output → optional tempering/heat soak (EN 14179) → lamination → edgework → IGU assembly.
• Standards: ASTM C1036 (flat glass), EN 410/ISO 9050 (optical/solar), EN 12150 & ANSI Z97.1 (safety), EN 1279 (IGU).
• Service life: around 25–40 years in façades; sealant selection and drainage detailing drive longevity.

Where it shines (use cases)

Offices needing glare control without blinds, hospitality lobbies after that golden-hour ambience, residential bays that want privacy in daylight, and transit hubs where maintenance is… let’s say “sporadic.” In fact, a recent mid-rise retrofit in Doha reported ≈12% HVAC savings year one, with measured glare reduction ≈30% at 3–5 p.m. It seems that tinted glass paid for itself faster than the lighting redesign.

Customization and feedback

Pick your thickness, edge polish, heat treatment, and IGU build-up; we’ll run EN 410/ISO 9050 calcs so you can hit energy models without guessing. Many customers say the bronze reads “classic” from the street but modern inside—privacy without feeling boxed in. To be honest, that’s hard to pull off with clear low‑E alone.

Origin: North Second Row, East Side of Dadong Logistics, Economic Development Zone, Shahe City, Xingtai City, Hebei Province.
