Intercept LiteLock™ Sealant Bead Application System

What is Intercept LiteLock™?

Intercept LiteLock™ is a new extruder tip and sealant bead application system developed by Vitro Architectural Glass for Intercept® insulating glass technology. Licensees of Intercept® technology that upgrade to Intercept LiteLock™ will benefit from enhanced efficiency, performance and quality improvements in the manufacture of insulating glass units (IGUs).

The patent-pending Intercept LiteLock™ nozzle tip applies sealant in a unique bead geometry that results in robust adhesion to the spacer metal substrate at near-finished bond line width. This reduces the amount of required squeeze-out during the roll-pressing process, so Intercept® spacer systems can run faster and at lower post-heating temperature. Intercept LiteLock™ also reduces energy consumption and consumable parts costs, making it the most energy-efficient upgrade to Intercept® technology.

Maximizing Efficiency and Quality

With Intercept LiteLock™, GED’s Intercept® Oven & Roll process can run at 30% to 50% faster processing speeds while also creating a wider manufacturing process window. This results in a more consistent, uniform and secure seal between the Intercept® spacer and the glass lite.

Intercept LiteLock™ Technology

Other benefits of the new Intercept LiteLock™ sealant bead application system include improved glass adhesion, enhanced service life of Intercept® IGUs and a reduction in sealant material used during the application process.

In addition to standard double glazed IGUs, the Intercept LiteLock™ system has been rigorously tested with triple glazed IGUs across multiple oven and roll press speeds and temperatures to establish effective processing recommendations that will ensure robust glass and spacer adhesion, including the center lite, which is traditionally difficult to bond.

Upgrading to Intercept LiteLock

Residential window manufacturers can upgrade their existing GED Intercept® spacer systems to Intercept LiteLock™ with a minimally invasive process. Intercept LiteLock™ is compatible with all generations of Intercept® technology as well as all current sealant and spacer types.
