PVB interlayers

Incorporate soothing colors into your architectural designs. When laminated between two sheets of glass, Vanceva interlayers enhance the safety and UV protection in architectural glazing. Now available in an array of natural earth tones, these polyvinyl butyral (PVB) films also bring greater aesthetics, warmth, and serenity to any architectural space. Traditional methods of making colored glass can be costly, particularly when the volume of colored glass is small. And not all colored glass may be appropriate for building codes and requirements. With Vanceva EarthTones, architects and designers have an innovative option to expand their creative boundaries and fulfill their vision without sacrificing structural integrity. Select from a ran...

Solar absorbing solutions for laminated glass Saflex® Solar PVB interlayers are high-visible light transmittance, infrared (IR) radiation-absorbing interlayers designed to enhance solar heat gain performance in laminated glass compared to monolithic clear glass and laminates made with conventional polyvinyl butyral (PVB) interlayer. They have the capability to meet or exceed many regulations for laminated safety glazing when properly selected, laminated, and installed. The ideal solar product eliminates UV and NIR energy while allowing as much visible light transmittance as possible. As shown in the below chart, Saflex Solar has the transmittance of a highly effective high-visible light transmittance solar product. Plus, Saflex Solar... More

Designed for extra strength in laminated glass Providing superior structural capacity versus conventional PVB, Saflex® Structural interlayer is a PVB interlayer designed for applications where interlayer rigidity and high glass adhesion requirements for laminated glass are critical.  In properly designed systems, Saflex Structural is capable of containing glass shards at high and low temperatures after impact and under load—even in open edge laminated glass.  Due to the strength and stiffness of the Saflex Structural interlayer, laminated glass can either sustain a higher uniform load for a given configuration or the glass thickness can be reduced while keeping the same load and area as compared to conventional laminat...

Enhanced safety for architectural laminated glass Globally, architects and designers rely on Saflex® Clear PVB interlayers in laminated glass to help meet regional standards for safety glass. Protecting people and property, Saflex interlayer adds post-breakage safety and security to laminated safety glass applications. Unlike monolithic glass, properly designed laminated glazing made with Saflex interlayer reduces the risk of injury from broken glass because the glass adheres to the interlayer after impact.  By holding glass in place, the interlayer provides protection by preventing the release of glass shards from becoming dangerous flying or falling glass fragments.  This may also help keep the system integral once broken&...

Blocks up to 99% of harmful UV rays up to 400 nm* In architectural design, natural light is visually appealing because it’s dynamic. It’s emotionally appealing because it connects us with the outside world. And it’s practical because many sustainable designs now call for effective daylighting. But natural light also brings damaging UV rays.  With Saflex® UV PVB interlayers, you can design to let sunshine in without worrying about UV radiation prematurely fading drapes, curtains, carpet, furniture, hardwood floors, wallpaper, photographs, framed documents, artwork, and anything else your clients like to show off indoors . . . including their skin**. Conventional Saflex PVB interlayers have a 99% UV screening cap... More

Storm and cyclone resistant interlayer for laminated glass Saflex Storm interlayers are specifically designed and formulated to meet the exacting building requirements for laminated glass in severe wind and windborne debris markets.  These are tough, resilient interlayers that provide rigidity, strength, glass adhesion, and protection against windborne debris and flying objects.  Laminated glass made with Saflex Storm PVB interlayer is designed to retain glass shards in post breakage scenarios.  Whereas no single product offers complete protect from a powerful cyclone or storm, these solutions can be used to help maintain the building envelope and aid in keeping the structure intact throughout the duration of severe wind st...

Innovative acoustic interlayer for laminated glass Modern building designs emphasize liberal use of glass.  However, sound transmission can be significant through ordinary glass.  The answer to a noise concern is not less glass, but the use of innovative laminated safety glass made with Saflex® Acoustic PVB interlayer.  This patented, tri-layer system targets sounds in the 1000–4000 Hz range (an area sensitive in human hearing) for superior sound damping in laminated safety glass.  As a result of Saflex Acoustic PVB interlayer availability, architects and engineers can design elegant spaces that reduce perceived loudness by up to 50%—decreasing transmitted sound up to 10 decibels versus non-laminated gl...
