| Laminated glass with standard PVB | Two or more glass sheets bonded with a polyvinyl butyral (PVB) interlayer. | When broken, the interlayer helps hold many glass fragments together and can reduce the risk of pieces falling out of the opening. The level of protection depends on the complete glass construction and its tested performance. | Widely used; offers a practical balance of safety, clarity, UV filtering, and cost for many building applications. | Edge exposure, moisture, glass thickness, interlayer thickness, and installation details matter. It should not be assumed to provide security or hurricane protection unless the complete system is designed and tested for that purpose. | Windows, doors, skylights, overhead glazing, and other locations where retained fragments are important. |
| Laminated glass with acoustic PVB | Standard laminated construction using a specially formulated PVB interlayer intended to improve sound reduction. | Provides the fragment-retention behavior of laminated glass when correctly specified and manufactured. | Can improve sound insulation compared with a similar construction using standard interlayer, particularly when the glazing is part of a well-designed sound-control system. | Acoustic results depend on the full window or façade, including glass thickness, air gaps, seals, framing, and installation. Check tested sound ratings for the complete assembly. | Buildings near roads, railways, airports, or other noise sources; offices and residences requiring better sound control. |
| Laminated glass with ionoplast interlayer | Glass sheets bonded with a stiff ionoplast interlayer rather than conventional PVB. | Can retain broken glass and, in specifically engineered and tested assemblies, support greater post-breakage stability than more flexible interlayers. | Higher interlayer stiffness can be useful where structural performance, reduced deflection, or post-breakage support is important. | Performance varies with the glass build-up, temperature, support conditions, and design. It is not automatically impact-, security-, or hurricane-rated; use project-specific engineering and test data. | Structural glazing, canopies, overhead glazing, balustrades, and applications with demanding design requirements. |
| Laminated glass with EVA interlayer | Glass sheets bonded with an ethylene-vinyl acetate (EVA) interlayer, commonly used in decorative and specialty laminates. | Can hold fragments together when the finished laminate is properly made and suitable for the intended application. | Can be used with decorative inserts and specialty materials; properties depend on the specific formulation and manufacturing process. | Do not assume all EVA products are suitable for exterior or structural use. Confirm long-term exposure suitability, adhesion, and compliance for the exact glass-and-interlayer system. | Decorative glazing, interior partitions, and selected specialty applications with verified product performance. |
| Laminated glass made with heat-strengthened or fully tempered plies | A glass construction choice, not a separate interlayer type: one or both glass sheets are heat-treated and then laminated with a suitable interlayer. | Heat-treated plies change how the glass breaks; the interlayer helps retain fragments. Fully tempered plies generally break into smaller pieces, while heat-strengthened glass typically breaks into larger pieces. | Can combine laminated fragment retention with the strength characteristics of heat-treated glass. The appropriate ply type depends on loading, thermal stress, and safety requirements. | Heat treatment does not by itself make glazing a certified safety-glazing assembly. Check the finished laminate, edge quality, heat-soak requirements where applicable, and project-specific standards. | Doors, façades, balustrades, overhead glazing, and locations where design loads or thermal conditions influence glass selection. |
