💡 6mm is the "everyday workhorse" of the tempered glass family — the most widely specified thickness for residential and light commercial applications. It offers the perfect balance of strength, weight, and affordability. While it lacks the stiffness of thicker options, it is more than adequate for standard windows, doors, canopies, balcony infill panels, and small shower enclosures. Its lightweight (~15 kg/㎡) makes it easy to handle, install, and transport.
6mm Tempered Glass — also known as 6mm Toughened Glass or 1/4 Inch Tempered Glass — is a lightweight safety glass produced by controlled thermal treatment. Quality 6mm float glass is heated to approximately 580-620℃ and then rapidly cooled with high-pressure, uniformly distributed air jets (rapid quenching). This creates a surface compressive stress layer (≥ 69 MPa) while the interior retains compensating tensile stress, delivering 4 to 5 times higher impact and bending strength than ordinary annealed glass.
6mm's unique positioning is: "the thickness that makes everyday architecture safer." It is the entry point into tempered glass — affordable enough for mass-produced windows and doors, yet strong enough to meet building code safety requirements for many applications. It is the default choice for residential projects where budget matters, but safety cannot be compromised.

This is one of the most-searched long-tail queries from procurement managers. The unit weight of 6mm glass is approximately:
| Glass Area | Approx. Weight |
|---|---|
| 1 m² | ~15 kg |
| 2 m² | ~30 kg |
| 5 m² | ~75 kg |
| 10 m² | ~150 kg |
| Single panel 1200×2400mm (2.88 m²) | ~43 kg |
💡 6mm is the lightest common tempered glass thickness — 25% lighter than 8mm and 58% lighter than 12mm. This makes it the easiest to handle, cut, drill, and install. For large-volume projects like residential window replacements or hotel balcony infills, the weight savings translate directly into lower shipping costs and faster installation.
Maximum Size: Up to 3300 × 13200 mm. Because 6mm is thin and lightweight, it can be produced in very large sheets — ideal for curtain wall spandrels, large storefront windows, and architectural glazing where weight must be minimized.

| Project Type | Typical Panel Size | Panel Count | Notes |
|---|---|---|---|
| Storefront window | 2150 × 4550mm | 100+ | Clear, polished edge |
| Curtain wall spandrel | 1575 × 3950mm | 500+ | Tinted, heat-soaked |
| Hotel balcony infill | 1680 × 2840mm | 300+ | Low-Iron, arrissed edge |
| Residential window replacement | 920 × 1530mm | 2000+ | Clear, seamed edge |
⚠️ The "non-cuttable" nature of tempered glass means all fabrication must be completed before tempering. 6mm is the easiest thickness to process.
Per the principle that each thickness page must have its own Search Intent + Application Intent + Procurement Intent, 6mm's unique positioning is "Everyday Safety Glass — the affordable, lightweight choice for standard architectural applications."
6mm tempered glass is the standard safety glass for residential windows in most building codes. It provides impact resistance, thermal break resistance, and meets safety glazing requirements for windows within 600mm of doors or floors.
For interior and exterior glass doors in residential and light commercial settings, 6mm tempered glass is the most cost-effective compliant option.
6mm tempered glass is widely used for entrance canopies, walkway covers, and awning panels where wind load is moderate and span is limited.
For balcony railings where the glass is fully framed (not frameless), 6mm tempered glass provides adequate strength at the lowest cost.
For compact shower enclosures in apartments and hotels, 6mm tempered glass is a budget-friendly option.
6mm tempered glass is the standard thickness for kitchen backsplashes and bathroom splashbacks — lightweight, easy to install, and available in any color via ceramic digital printing.
For museum display cases, retail showcases, and picture frames, 6mm tempered glass provides safety without excessive weight.

A:
A: Yes, but must be laminated (6mm+PVB+6mm) for safety. Monolithic 6mm tempered glass is not recommended for overhead applications due to the risk of falling glass if broken.
A: 6mm glass weighs approximately 15 kg/㎡. A 1.2m × 2.4m panel (2.88 ㎡) weighs about 43 kg — easily handled by two people.
A: No. Once tempered, all sizes and edges are fixed. 6mm tempered glass cannot be cut, drilled, or ground. All processing must be done before tempering.
A: Maximum single-panel fabrication size is 3300 × 12300 mm. 6mm can be produced in very large sheets because it is lightweight and easy to quench uniformly.
A: Yes — but only before tempering. We support lock holes, hinge holes, handle holes, and other standard openings. Hole edge distance ≥ 2× glass thickness (≥ 12mm).
A: Clear 6mm tempered glass offers ≥ 92% light transmittance; with an Ultra-Clear (Low-Iron) substrate, transmittance reaches ≥ 94%. 6mm has minimal green tint due to its thinness.
A: Yes. 6mm tempered glass is commonly used as the inner or outer lite of laminated glass (6mm+PVB+6mm) for safety glazing, and as one lite of an IGU (6mm tempered + spacer + 6mm tempered) for double-glazed windows.
A: Standard MOQ is 50 ㎡. Larger orders (500+ ㎡) receive volume discounts. Lead time is 15-20 days standard; 15-20 days for panels with holes or cutouts.
