36 Post Breakage Performance at room temperature Performance at +21 C / 70 F Standard PVB 1.52mm Trosifol ES 1.52mm SentryGlas 0.89mm Only SentryGlas (0.89 mm and 1.52mm) and Trosifol ES sustained loads of 400 Kg. PVB could not sustain a 100Kg load 36

37 Post Breakage Performance at elevated temperature Performance at +50 C / 131 F Standard PVB 1.52mm Trosifol ES 1.52mm laminate SentryGlas ionoplast 0.89mm Only SentryGlas ionoplast (0.89 mm or 1.52 mm) could sustain a 100 Kg load for 30 minutes 37

38 Trosifol family of Structural Interlayers Trosifol Extra Stiff (ES) Application requires a structural interlayer Design temperatures up to 30 C Lower cost may be possible When to use? SentryGlas Ionoplast SentryGlas is specified in the application because of its unique properties Application requires the highest structural performance over a wide temperature range Open edge applications or sealant compatibility Thinner glass construction is highly possible Open Edge Applications SentryGlas interlayer and Trosifol ES interlayer are both high modulus stiff interlayers which provide a range of performance to meet all of your structural glazing demands 38
