3.22 meters is the maximum width available for Saflex® PVB interlayers.
Yes, it is possible in simple curved glazing. Please contact the laminators who can provide price quotations for a specific project. Click here to go to our Glass Manufacturer Locator.
All architecturally targeted Saflex PVB interlayers will screen out 99% UV radiation up to 380 nm (including UV-A, B, and C).
Only a glass manufacturer can offer a warranty on the final glass construction.
Testing conducted in both natural (Florida) and accelerated xenon weathering exposures have confirmed that—by all measurement systems—when properly laminated and installed, glass laminates produced with Saflex PVB interlayer will provide acceptable quality when the edges of the laminate are exposed to normal weathering.
Eastman cannot and does not recommend specific sealants. Eastman has extensive experience with sealants using Saflex® PVB interlayers. The thoroughness of the application of sealants is just as important as the chemical interactions between the sealants and the PVB. The least reactive sealant poorly installed will perform worse than the most reactive sealant properly installed. Other effects, such as physical performance, weathering, paintability, and application ease, enter into the decision of which sealant to use. Often the framing will hide any cosmetic effects that may appear at the edge of the glass.

Most sealant suppliers will give information on which of their sealants is compatible with PVB interlayer.
Eastman advises the use of strengthened laminated glass to avoid thermal breakage. Thermal breakage may occur everywhere, from hot countries (e.g., Spain) to cold regions (e.g., Scandinavia).
Consequently, it is recommended to assess the risk of thermal breakage for EACH project where Saflex will be used for exterior applications (facades, roofs, sunscreens, balconies, etc.). If the simulation shows that there is a risk, heat-strengthened or fully tempered glass should be used in place of annealed glass. Of course, for indoor applications (partition walls, balustrades, etc.) the risk of thermal breakage is slight, as there is usually no direct sun radiation on the laminated glass.
The Vanceva color system is a range of colored PVB (polyvinyl butyral) interlayers. The Vanceva color interlayer system can produce a broad spectrum of colors and atmospheres that are unachievable using stock selections of glass. With this system, interlayers can be combined to produce over 17,000 transparent, translucent, or opaque color options to help you create the perfect tone and intensity.
Laminated glazing is formed by permanently bonding these protective interlayers between two or more sheets of glass, creating a product that can meet or exceed some of the most stringent safety and security standards worldwide.
No, Eastman is a manufacturer of glazing interlayers; Saflex is a brand name for those interlayers.
Vanceva® is a brand within the Saflex® polyvinyl butyral interlayers business unit of Eastman Chemical Company. The products we manufacture are used by glass companies to fabricate laminated glass. These glass companies then sell the laminated glass to manufacturers of insulated glass windows and doors, furniture and interior glass-wall systems, curtain walls, and skylights so that they can fabricate the glass into the finished installed product.
