Tambest Oy – certified manufacturer of SentryGlas® laminated glass, experts in complex glass structures

SentryGlas_sertifikaatti_Tambest

Tambest Oy is a certified manufacturer of SentryGlas® laminated glass, and our machinery and expertise allow us to create even the most challenging glass structures.

The SentryGlas® interlayer from the Kuraray’s AIS Structural product family is five times stronger and up to 100 times stiffer than conventional laminating materials.  With this kind of strength, the glass can be a more active structural element in the building envelope, opening up design possibilities that didn’t exist before.

Besides its strength, SentryGlas® ionoplast interlayer retains its clarity – even after years of service. Unlike other interlayers, SentryGlas® ionoplast interlayer is much less vulnerable to moisture exposure or yellowing over time.
