SGP
IONOMER, RIGID, SAFETY INTERLAYER

SGP is yet another type of interlayer film (ionomer), suitable for applications where human well-being and property protection against natural or man-made threats is of outmost importance. SGP (or SentryGlass), offers the durability and protection of a rigid interlayer, combined with the benefits of “standard” interlayers, such as UV screening, light transmission and noise abatement.

VAS GLASS offers SGP interlayer laminate glass certified according to the architectural and safety European Norms EN 12600, EN 356, and EN 1063.

SGP interlayer offers five times the shear strength and up to 100 times the rigidity of conventional PVB interlayer , for endurance in heavier loads and stronger impacts. This makes it an excellent candidate for demanding architectural and structural applications.

Contrary to other interlayer films, SGP, due to its ionomer composition is less susceptible to moisture penetration and changes in color (haze) over time, even when the edges are exposed to the elements.

VAS R&D EXPERIMENT
FOUR POINT BENDING, ACCORDING TO EUROPEAN NORM ΕΝ 1288-3

The results of measuring the safety glass strength and deflection using VAS GLASS in-house specialized apparatus and software are shown below. For a given effective bending stress level, SGP laminate is equivalent to float glass.

MAIN BENEFITS OF SGP:

Protection

In the event of breakage, the glass fragments, independent of their size, remain rigidly attached on the SGP interlayer, prohibiting their scattering and therefore reducing the risk of injury.

Safety

Can be used in laminate applications designed for resistance to bullets, cyclones/typhoons and bomb blasts.

Radiation control and transparency

Can be applied on low-e coated glass for achieving energy efficiency, while maintaining high transparency levels. The superb transparency of the SGP safety glass interlayer allows for its combination by architects and designers with extra-clear, low-iron float glass.

Durability

It exhibits excellent structural strength (higher than that of float glass), as well as resilience against discoloration and development of haze, even when exposed to the elements for very long periods of time.

Flexibility in design

Can be combined with any type of float glass for a wide range of applications, leading to thinner and lighter solutions (up to 40% lighter than float glass with similar characteristics). Its use with lighter support fixings leads to a much lighter system than ever introduced before. This architectural glass factor can result in longer panels, a reduced number of support fixings and lighter-weight support structures, reducing their visual impact as well as providing cost savings.
