Providing Unparalleled Architectural Freedom: Saflex™ Structural PVB Receives French National Approval

Eastman, the leading manufacturer of Saflex™ PVB for architectural applications, is thrilled to announce the prestigious French national approval granted to laminated glass featuring Saflex Structural (DG) interlayer. This remarkable development paves the way for enhanced project flexibility and design durability, opening new horizons for architects and glass laminators in France.

A Game-Changing Breakthrough for French Building Architecture

For years, the utilization of specialty interlayers, even for non-structural glass design, faced significant limitations in French building architecture. However, the landscape has undergone a transformative shift with the recent French national approval (Document Technique d’Application or DTA) bestowed upon Saflex Structural (DG) interlayer.

Unparalleled Approval for Saflex Structural

While stiff PVB interlayers have been embraced by the European architectural market for nearly a decade, their acceptance and adoption in France have remained elusive due to stringent qualifications governing the use of nonstandard interlayer products in glass design. Saflex Structural stands apart as the sole stiff PVB interlayer approved for application in France. This prestigious approval stems from exhaustive testing conducted by the Scientific and Technical Center for Buildings, complemented by registration with the esteemed French certification body CEKAL.

Empowering Architectural Creativity with Enhanced Flexibility

Oliver Osborne, the commercial director of AMI architecture at Eastman, expressed his enthusiasm, stating, “Glass serves as a pivotal design element in architecture. The endorsement by the French Scientific and Technical Center for Buildings (Centre Scientifique et Technique du Bâtiment; CSTB) of laminated glass incorporating our Saflex Structural PVB interlayer presents a remarkable advantage for French architects, facade engineers, and glass laminators. They will now enjoy greater freedom and an expanded array of product options to realize sustainable designs.”

Unlocking New Design Possibilities

This approval empowers the creation and utilization of laminated safety glass utilizing Saflex Structural as the interlayer, capitalizing on its enhanced mechanical properties. Facade engineers benefit from the provision of interlayer modulus values for various load scenarios, unlocking architectural flexibility and a wider range of options. Notably, reducing glass thickness in laminated glass contributes to embodied carbon reduction in sustainable construction—a feat made possible by special stiff or structural interlayers such as Saflex Structural.
