What Are Insulated Glass Units?
Insulated Glass Unit Facts are essential for understanding how modern windows deliver superior comfort and performance. An Insulated Glass Unit (IGU)—also called double-pane or triple-pane glass—consists of two or more panes of glass separated by a metal spacer and sealed airtight. Between the panes is an inert gas, like argon, that dramatically reduces heat transfer.
This system not only minimizes heat loss during Ohio winters but also blocks excessive heat during summer months. The result? Lower energy bills, improved indoor comfort, and reduced condensation on interior glass surfaces.
Why Cardinal IG Units Lead the Industry
When it comes to performance, few manufacturers match the precision and reliability of Cardinal IG Units. With over 500 million insulated glass units under warranty, Cardinal has proven their products can stand the test of time.
Inside each Cardinal unit, you’ll find four core components that define excellence:
- Primary Seal: Polyisobutylene (PIB) creates a moisture-resistant argon gas barrier that ensures long-term protection.
- Secondary Seal: A durable silicone adhesive reinforces the bond, maintaining structural integrity against temperature fluctuations.
- Spacer System: A stainless-steel spacer eliminates chemical fogging and reduces condensation stress.
- Desiccants: Moisture-absorbing beads that prevent fog and frost at subzero temperatures.
These design elements help achieve an incredible 0.2% seal failure rate over twenty years—far better than the industry average of over 9% in just fifteen years. That’s precision engineering at work.
Energy Efficiency and Comfort Benefits
One of the most valuable Insulated Glass Unit Facts is how much they can save homeowners in energy costs. Up to 30% of heating and cooling energy can escape through inefficient windows. By upgrading to Cardinal IG technology installed by Thrush & Son®, homeowners benefit from:
