Purpose

This document ensures consistent and accurate labeling of insulated glass (IG) units. Proper labeling is significant because:

• Quality Control: Labels identify critical unit characteristics—tempered, wildfire-rated, hard-coat, etc.—affecting installation, handling, and performance.
• Safety: Labels communicate safety information to installers and end users about glass properties and handling.
• Traceability: Barcode labels enable tracking of glass-only and overfill orders through production.
• Operational Efficiency: Standardized labels help production teams quickly identify units and route them correctly through manufacturing stages.
• Customer Communication: Labels ensure correct specifications reach installation crews and meet customer requirements.

This process maintains manufacturing consistency, reduces errors, ensures compliance with safety standards, and enables efficient order fulfillment.

Definitions

Original Label: A label placed on the clear side of the IG unit, approximately 2-3 inches from both edges of the top right corner, identifying the glass unit.

Wildfire Label: A sticker applied to units designed to withstand extreme heat without shattering, where one lite is tempered and the other is annealed.

Tempered Label: A sticker applied to units where both lites have been heat-treated to increase strength and safety, causing the glass to break into small pebbles rather than sharp shards.

Hard-coat Label: A sticker identifying units with a hard-coat low-e coating (a touchable energy-efficient coating) that requires special cleaning considerations.
