Eastman - Interlayers
laminated glass


Solutia’s Saflex business is the most trusted name in polyvinyl butyral (PVB) interlayer technology for laminated glazing - delivering outstanding performance and durability, backed by reliable and knowledgeable service. As a result, it is found in nearly 40 percent of laminated architectural and automotive glass worldwide.

Residential and Commercial Architectural Markets
Saflex interlayers are valued in architectural applications for the safety, security, acoustic and solar benefits provided. From hurricanes to bomb blasts, Saflex provides safety and security from shattered glass by holding the glass to the interlayer on impact. Saflex interlayers provide protection from damaging ultraviolet solar rays, in addition to acoustic sound dampening benefits that are valued in spaces such as airports, restaurants and industrial complexes.

Security image


Burglars, bombs and bullets are no match for laminated glass made with Saflex interlayer

The desire for living and working in open, sunlit, glass-clad buildings has come face-to-face with the need to assure that building structures provide occupants with optimal security. Properly designed and installed laminated glazing systems made with Saflex interlayer can provide remarkable protection from forced entry, bomb blasts and ballistics.

Storm/Hurricane image


While no single product offers complete protection from hurricanes, typhoons and violent storms, laminated glass windows and doors made with Saflex , Saflex HP or Saflex Storm protective interlayers can be a critical first line of defense.

In properly designed systems, laminated glass effectively withstands these natural forces to help maintain the critical exterior envelope. If broken by impact from wind-borne debris, the glass fragments bond firmly to the protective interlayer, continuing to safeguard building occupants and contents.

Designing for Sound Reduction

Modern design trends emphasize the liberal use of glass in building exteriors and interiors, while building owners and occupants still demand the highest level of environmental comfort. Sound transmission into building spaces generally occurs through the weakest element typically, glazing constructed of ordinary window glass.

In response, architects and designers must consider protecting a buildings environment from increasing noise levels when specifying glazing materials for new and renovated structures. The proven sound-damping performance of Saflex acoustic interlayers offers architects and specifying engineers a clear and compelling alternative for addressing these complex demands.

UV Control image

UV Control

Laminated glass made with Saflex interlayer absorbs solar radiation. As with monolithic heat-absorbing glass, if design conditions such as high solar radiation intensity or absorption increases thermal stress, heat strengthening the glass plies is a desirable option. Laminated heat-strengthened glass is ideal for spandrel and other applications where the fallout of glass after breakage is a safety and security concern.

Solar and thermal energy controls must be carefully considered when designing and specifying a glazing system. This is because the amount of energy transferred through glazing impacts the costs of heating, cooling and lighting a building. That's where Saflex interlayer can help.

Saflex interlayer in combination with appropriate glass types, can effectively manage heat build-up, as well as help reduce fading and damage from ultraviolet (UV) radiation. Much like sun block, Saflex interlayer screens out and virtually eliminates most harmful and damaging UV rays. In fact, Saflex interlayer filters out almost 99% of these rays which is the equivalent of Sun Protection Factor (SPF) of 50+. Unchecked these rays can cause health concerns and cause fade damage to interior furnishings, fabrics, drapes, wall coverings, photographs and artwork.

Color image


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. But now, architects and designers have an innovative option to expand their creative boundaries and fulfill their vision without sacrificing structural integrity: Saflex Earth Tones, a collection of polyvinyl butyral (PVB) color interlayers that add value to glass.

Select from a range of 11 Earth Tones in shades of blue, grey, green, brown, and bronze�colors that are all similar to industry standard glass tints when laminated in clear glass. Saflex color interlayers allow architects and designers to achieve varying light transmissions without having to vary glass thickness or sacrifice structural performance.
