Glass Specifications

How to define a complete architectural glass specification for accurate technical review and production.

Specification framework

Define the complete glass make-up.

A buildable specification identifies every material and process in the order it will be manufactured. Dimensions alone are not enough: the application, performance, safety, appearance and destination standard all affect feasibility.

Information to include

Glass build-up

Substrate, nominal thickness, heat treatment, laminated plies, interlayer, cavity, spacer and gas fill.

Processing

Finished size, edgework, holes, notches, cut-outs, printing, coating surface, orientation and shape.

Project criteria

Application, design loads, safety function, thermal and optical targets, standards, quantity and delivery.

Typical production references

Tempered glass3–19 mm250 × 250 mmUp to 3,300 × 14,500 mm

Laminated glass6–60 mm overall300 × 300 mmUp to 3,300 × 12,000 mm

Insulating glass3–19 mm panes; 6–20 mm cavity200 × 300 mmUp to 3,300 × 7,000 mm

Curved glass5–19 mmRadius dependentUp to 2,400 × 5,000 mm

These are typical capability references found in the Chinese architectural-glass supply market, not automatic production guarantees. Final limits depend on make-up, geometry, fabrication, coating and available equipment.
