Optional cutout
Layered build‑up
Add glass and interlayer plies. Weight equals area multiplied by total areal density (Σ thickness × density).

Example Data
| Example | Description | Inputs | Expected weight (approx.) |
|---|---|---|---|
| 1 | Rectangular panel | 2000×1000 mm, 6 mm, soda‑lime | ~30 kg |
| 2 | Laminated panel | 2500×1200 mm, 6+6 with 0.76 PVB | ~95 kg |
| 3 | Round tabletop | Diameter 1000 mm, 10 mm, soda‑lime | ~49 kg |
Values are indicative; actual weight varies with material densities and tolerances.
Formula used
Weight = Area × Areal density × Quantity × (1 + Waste%/100)
Areal density (kg/m²) = Σ(thicknessi in m × densityi in kg/m³)
- Rectangle area = L × W
- Circle area = π × (D/2)²
- Half circle = ½ × π × (D/2)²
- Quarter circle = ¼ × π × (D/2)²
- Triangle area = ½ × base × height
- Net area = Panel area − Σ Cutout areas × quantities
Densities used (defaults): soda‑lime 2500 kg/m³, borosilicate 2230 kg/m³, aluminosilicate 2600 kg/m³, PVB 1100 kg/m³, SGP 950 kg/m³.
How to use
- Choose Simple for single‑ply panels or Advanced to build laminates.
- Select your unit system and panel shape, then enter dimensions.
- For cutouts, select shape, provide size, and quantity if applicable.
- Pick a glass type and thickness, or add layers in Advanced.
- Set quantity and optional waste allowance to cover breakage or offcuts.
- Click Calculate to update results; Add to table to save.
- Use Download CSV for spreadsheets or Download PDF to share.
FAQs
No. Tempering alters strength and breakage behavior, not bulk density. Use soda‑lime density unless specified by supplier.
Very close. We sum each glass ply plus interlayer mass. Tolerances and moisture can introduce small variations.
Usually negligible compared to glass mass. For critical lifts, add manufacturer‑provided spacer weights.
Metric and imperial. Inputs support mm, m, in, and ft. Results show both kg and lb automatically.
We multiply total weight by (1 + waste%/100). Use it for breakage, trimming, and handling contingencies.
Yes. Use the cutout controls to subtract circular or rectangular openings. For complex patterns, approximate by summing several cutouts.
Defaults: PVB ~1100 kg/m³, SGP ~950 kg/m³. Adjust if your supplier provides specific data.
Select circle, half‑circle, or quarter‑circle shapes. For arcs or more complex geometries, estimate their area and enter equivalent dimensions.
Yes. Use “Add to table” after each calculation. Then export the table to CSV or PDF.
Check units, thickness entries, and cutouts. Also verify whether waste allowance is set above zero.
Not usually. Most coatings add minimal mass compared to the glass substrate.
Use this for weight estimation and logistics. For structural design, consult applicable codes and a qualified engineer.
You may add their mass manually by increasing waste allowance, or calculate separately and add to totals.
You can model them as layers using densities: polycarbonate ~1200 kg/m³, acrylic ~1180 kg/m³.
No software limit. Practical limits depend on handling capacity, equipment, and transport.
We convert to ft² for area and pounds for weight, alongside metric values for clarity.
