ADVANCED INTERLAYER SOLUTIONS
Aesthetics and safety were the basic premises for the specification of SentryGlas® ionoplast interlayer in the guard rails of Barueri Arena, considered one of the most modern sports facilities in Brazil today.
More than a municipal soccer stadium, it is a multi-purpose arena used for various entertainment and sport events. Satio Tomita, architect of the Barueri Arena project sought to replace the original metal guard rail with a glass solution that would provide maximum visibility and safety.
SentryGlas® enabled the use of a thinner, lighter laminated glass solution, one with better impact resistance, higher transparency, and less sensitivity to moisture and other weathering effects. The laminated glass also complies with ASTM E 2353 and ASTM E 2358 standards for glass in railing systems.
SentryGlas® also enabled the use of larger glass panels, meeting the required pressure loads and creating a transparent barrier around the football field.

Using finite element analysis, it was possible to prove that self-supporting PVB solutions would require thicker and heavier glass. In addition, SentryGlas® weathering data supported an exposed edge design, thus, enabling a total obstacle- free view.
The post-breakage performance of SentryGlas® laminated glass increases safety and protects people below the glass from the danger of falling glass. The higher the tension, the greater the risk of glass breakage. The ASTM standard allows a maximum tension in the glass according to a specified time duration and exposure temperature.
