The demands for high performance façade, where the infill glazing material plays an expanded functional role, are continuing to drive the selection of laminated glass in modern architectural projects.
Ionoplast (ionomer-based) interlayers have been in existence for several decades now. However, the most significant market introduction was in 1998 with the launch of SentryGlas® interlayer. This was developed specifically for construction applications, with the focus on improving the structural properties and weather resistance of the laminated glass, rather than PVB.
Over the last 15 years, this interlayer has seen several improved developments. Initially developed for the building envelope protection required for hurricane glazing in the USA and large missile testing requirements, the use of SentryGlas® interlayer has now expanded considerably as structural engineers have recognized that the performance benefits developed for hurricane applications could also be beneficial for many other aspects of a building, including façades, overhead glazing, balustrades, glass floors, staircases, doors and partitions.
Compared to PVB interlayers, SentryGlas® ionoplast interlayer is tougher, 100 times stiffer and performs better over a wider temperature range.
