The Challenge
Why This Product Exists
Single-pane glass offers virtually no thermal or acoustic insulation, making buildings uncomfortable, noisy, and energy-intensive. Even basic double glazing with aluminum spacers leaves significant room for improvement, with edge condensation and thermal bridging reducing overall window performance by 20-30%.

Common Questions
Frequently Asked Questions
Double glazing has two glass panes with one air/gas cavity. Triple glazing adds a third pane and second cavity, providing approximately 30-40% better thermal insulation. Triple glazing is recommended for cold climates, Passive House projects, and applications requiring maximum energy efficiency.
Air is the most economical option. Argon improves thermal performance by ~15% over air at minimal additional cost — it's the most popular choice. Krypton provides ~40% improvement over air but at higher cost, recommended for ultra-high-performance applications where cavity width is limited.
With standard spacer systems, IGUs typically last 15-20 years. With TPS/4SG warm edge technology, unit lifespan extends to 25+ years with minimal gas loss and no edge seal degradation.
Yes. Asymmetric configurations are common — for example, tempered Low-E on the exterior and laminated clear on the interior. We engineer each unit to optimize performance for the specific application.
