IG Moves Forward: Smarter Manufacturing Lines and Thinner Units Drive Efficiency
by Dave Cooper
The insulating glass (IG) sector of our industry continues to advance. New technical upgrades focus on automation, vacuum insulating glass (VIG) and thinner, more efficient triple-pane units. These developments help meet stricter energy codes and improve final product offerings.
Automation now defines modern production lines. One tempering oven manufacturer offers a tempering line that operates on autopilot. This system manages mixed production without an operator. It eliminates human error and increases equipment effectiveness.
Robotic systems also automate furnace loading and integrate quality control sensors for final product topographical imaging. These systems monitor clear, tinted and low-E glass processing in real time. They adjust parameters automatically to prevent defects and reduce waste.
Artificial intelligence (AI) will also come into play for predictive control of processes to maximize volume and minimize costs—all while producing the highest quality products.
Meanwhile, VIG is gaining crucial market acceptance globally. Europe leads the way in constructing new production lines. One company received a certification that allows use in vertical glazing without project-specific approval. It simplifies the specification process across Europe.
A few companies now offer turnkey VIG production lines for glass in and VIG out. One study calculated the need for 250 VIG production lines to supply the base requirements in North America.
Thinning Out
At the same time, the thin-triple segment is transforming manufacturing methods. With a center lite that’s less than a few millimeters thick, entire IGUs approach the thickness and weight of a standard double-pane unit. This solves a major window fabrication problem. High-performance IG can be installed in existing frames without modification. Major window manufacturers are now scaling production. This increased volume will help lower costs.
IG integration with smart glass is another key advancement. Production lines are now developed to accommodate electrochromic glass. Leading equipment companies have demonstrated automated assembly of these dynamic IG units. This progress makes smart windows more viable for large projects. They can be integrated into building management systems for optimized daylighting and solar heat gain control. Imagine combining this technology with VIG—all the benefits of solar heat gain control plus unprecedented thermal insulation. Only when manufacturing is sufficiently scaled up will this technology’s cost be sufficiently lowered for the value to be realized.
These technical upgrades focus on practical benefits. Automated lines increase production consistency and hence quality. New VIG and thin-triple units provide options for high-performance projects. Together, these innovations help deliver the energy efficiency that modern construction demands.
