Thin Triple Glass: Performance Without Compromise

Across North America, energy code requirements are becoming increasingly stringent. In some areas, stretch codes can require fenestration systems with U-factors as low as 0.25. With U-factors for ultra-thermal storefront systems generally around 0.3 -0.45, this can make meeting local codes both challenging and expensive. In addition to demanding energy code requirements, green building certifications, utility rebate programs and corporate ESG commitments are all driving demand for storefront solutions that reduce building energy consumption. 

The good news is that advanced glazing solutions can now improve U-factors without the need for costly replacements of curtain wall or framing systems. Through advanced thin triple glazing technology, ultra-thermal storefront systems, such as Kawneer’s Trifab® 451UT Framing System, can achieve U-factors of 0.25 or better while maintaining design flexibility and staying within budget. 

Enhancing Ultra-thermal Performance 

When paired with ultra-thermal storefront framing systems, thin triple glass can help projects meet or exceed even the most demanding stretch codes. With center-of-glass U-factors as low as 0.10-0.12, systems can achieve overall U-factors between 0.19-0.22. This enables compliance across all climate zones, while maintaining the transparency and aesthetic expected of a modern storefront design. 

Specifying & Installation Made Simple 

At around 30% lighter than conventional triple glazing, thin triple units reduce structural loads and open new possibilities for larger glass sizes. They fit seamlessly into standard 1″ IGU-compatible systems, requiring no frame modifications or special reinforcements, greatly simplifying specification and installation. 

Thin triple glass center-of-glass values can be plugged directly into Kawneer’s thermal calculator to quickly and reliably calculate the overall system performance.
