Convection in Glass Lamination: Future-Proofing Your Process

Lamination has become an essential process in modern glass processing, helping to enhance glass strength, stability, and sound insulation. Its popularity has surged not only because it allows for creative and innovative glass designs but also due to increasingly stringent safety regulations within the glazing industry. Lamination is a straightforward way to add more value to glass, offering processors an opportunity to provide safety, durability, and design flexibility, with a guaranteed return on investment in most cases.

However, as the market and regulations continue to evolve, the lamination technology currently in use is struggling to keep pace with these changes.

The Evolving Demands of Design and Regulation

While lamination offers more design possibilities, today’s architecture demands even more complex glazing solutions. This includes the use of coated glass, painted glass, and irregularly shaped glass. The variety of glass types required is far more diverse than what lamination technologies were originally designed to handle, posing a challenge for glass processors.

In addition, safety regulations are constantly being updated to ensure that glass products meet the highest standards. Lamination technology must, therefore, evolve to process glass in compliance with these changing regulations. Unfortunately, many of today’s lamination technologies are not equipped to handle these increasingly complex demands.

Outdated Radiation Technology in Lamination

Many of the lamination furnaces in use today still rely on radiation technology. However, radiation efficiency is highly dependent on the type of glass being processed. Different glass types, especially Low-E glass with edge deletion, absorb radiation differently, making it difficult to laminate effectively using traditional radiation methods.

One of the biggest drawbacks of radiation furnaces is that they often lead to waste—either by applying too much or too little heat during the lamination process. This becomes even more problematic as the range of glass types continues to expand, adding complexity to machines that were designed with traditional radiation technology in mind.

Convection: The Future of Lamination

So, how can glass processors ensure they’re future-proofing their lamination processes?

The answer lies in convection technology.

Research has shown that convection-based lamination systems can maintain consistent temperature control regardless of the glass type. Unlike radiation, which is dependent on the specific characteristics of the glass, convection heating provides uniform heat distribution, minimizing waste and ensuring more efficient processing. Even challenging materials like Low-E glass with edge deletion behave just like standard clear glass when exposed to convection heat, eliminating one of the biggest hurdles of traditional radiation methods.

This transition from radiation to convection is backed by decades of successful use in glass tempering technology. For years, convection heating has been a proven method for processing various types of glass with different thicknesses and properties. Now, this technology can be leveraged to laminate clear, Low-E, painted, and even irregularly shaped glass with ease and precision.

A Game-Changer for Glass Processors

By adopting convection technology, glass processors can future-proof their operations. The ability to process a wider range of glass types with greater efficiency and fewer resources will make lamination processes more versatile and less wasteful, all while meeting the evolving demands of both design and regulation.

With convection heating, glass processors no longer need to worry about adjusting their processes to suit each specific glass type. This new approach offers greater flexibility, energy savings, and improved results across a broader spectrum of glass materials.

In the competitive world of glass processing, staying ahead of technological advancements is crucial. As lamination technologies continue to evolve, convection heating offers a reliable, efficient, and cost-effective solution to ensure your business can handle the glass challenges of tomorrow.
