Coated Glass
LOW‑E GLASS
Low-emissivity (Low-E) glass carries a microscopically thin metallic or metal-oxide coating that reflects infrared heat while allowing visible light to pass through, reducing heat transfer without significantly darkening the glass. Available in single-, double-, and triple-silver configurations for different climate performance targets.

Key Features
Reduces heat loss in cold climates and heat gain in hot climates, maintains high visible light transmittance versus tinted or reflective glass, and is available in offline (sputtered/soft-coat) and online (pyrolytic/hard-coat) formats.
Where This Glass Is Used
Curtain walls, windows, doors, and any glazing application targeting energy code compliance or thermal comfort.
Manufacturing Process
- Magnetron sputtering (offline/soft-coat) — Multiple ultra-thin metallic and dielectric layers, including one or more silver layers, are vacuum-deposited onto the glass surface.
- Pyrolytic coating (online/hard-coat) — Metal oxide coating is applied during the float process while the glass is still hot, producing a more durable, temperable coating.
- Silver layer configuration — Single-, double-, or triple-silver layers are selected to balance visible light transmittance against solar heat gain rejection.
- Temperability — Soft-coat Low-E requires tempering-compatible formulations; hard-coat Low-E is inherently more durable and scratch-resistant for handling.
Applications & Use Cases
- Curtain Wall & Window Glazing — Standard specification for commercial and residential energy code compliance.
- Green / Net-Zero Buildings — Core component of high-performance building envelopes targeting LEED or net-zero energy goals.
- Cold-Climate Glazing — Higher-SHGC coatings selected to admit passive solar heat while retaining warmth.
- Hot-Climate & Solar Control Glazing — Lower-SHGC, triple-silver coatings selected to reject solar heat while maintaining daylighting.

Technical Service
We support your project from drawing review to delivery, not just order fulfillment.
- Drawing & Spec Review — Shop drawings and project specs are reviewed before production to confirm sizes, tolerances, and edge/hole details match your requirements.
- Testing & Documentation — Mill test certificates, thickness/strength test reports, and compliance documentation provided for project submittals.
- Technical Consultation — Our team advises on coating, thickness, and configuration selection to meet your project's structural and energy code requirements.
Customization
- Custom Cut Sizes & Shapes — Curved, notched, cut-corner, and irregular shapes fabricated to your CAD drawings, not limited to standard rectangles.
- Edgework & Drilling — Polished, beveled, or seamed edges, plus precision hole drilling and cutouts for hardware and fittings.
- Coating & Printing Options — Combine with Low-E coating, tinting, or ceramic silkscreen/digital printing on the same order.
Packaging & Shipping
- Export-Grade Crating — Reinforced wooden A-frame or flat crates with edge protection, built for ocean freight handling.
- Container Loading — Load plans optimize container utilization while maintaining safe glass spacing to prevent transit damage.
- Shipping Documentation — Packing lists, certificates of origin, and mill certificates prepared in advance for smooth customs clearance.
- Lead Time — 7days in 12'' sample; 15days in mock up sample; 35days in project order.
