SGP Laminated Glass

SGP (SentryGlas Plus) is another popular security interlayer used in laminated glass, with increased strength and security. AJJ offers SGP laminated glass for commercial and residential glazings.

What is SGP Laminated Glass

SGP interlayer for external frameless glass balustrades.

SentryGlas Plus is an ionoplast interlayer that is used to laminate glass and boasts extremely high weather resistance and strength levels.

The two are usually manufactured using the same process of applying heat and pressure to the glass to melt the layer in between which then acts as a glue, bonding the panes together.

The glass that uses this tough plastic interlayer is more costly than glass that uses PVB, however, it has many advantages such as greater clarity.

Benefits of Sentry glass

Why choose Sentry glass

Enjoy uninterrupted views

Using a SentryGlas™ interlayer allows unobstructed views, which means that you can enjoy the view without seeing a handrail, or interlinking clamps in your way.

Peace of mind

If safety is a priority for your loved ones, choose a SentryGlas™ interlayer. Its unique design allows for the glass to remain erect and intact – even if both panes of glass break.

Different applications – same result

Whether it is a glass canopy, windbreak, balustrade, or floor – SentryGlas™ interlayers offer the ultimate protection.
