A special logistics and transportation system, high-performance raw materials and outstanding know-how as a result of more than 40 years“ experience in the sector: these are the secrets of Henze-Glas for the design and manufacture of the largest insulating glass unit in the world. The production, assembly and transportation of remarkably large insulating glass units, with a variety of shapes and sizes, have become the Henze-Glas hallmark over the years. This Lower Saxony German company has challenged the current technological and logistical frontiers by exhibiting a record-sized insulating glass unit at the recent Glasstec event. Many weeks of intense work by 45 specialized engineers led to the installation of a one-of-its-kind glass structure at the fair: this special insulating glass unit not only guarantees top performance in terms of thermal insulation (Ug-Value: 1.6 W/m2), it is also the largest ever in its category with a record size of 3,300 x 18,000mm, weighing 4,455kg and a triple-sheet structure of float glass with each sheet being 10mm thick. Even though this product was manufactured for demonstrative purposes only, Henze-Glas was able to exhibit the true potential of its technological know-how with regards to the safety and quality of the company“s other, smaller-sized products. Dietmar Henze, chief executive officer of Henze-Glas, comments: With this panel we“ve taken an important step towards increasingly extreme formats. We“ve accomplished something others believed to be impossible or would never have imagined, and we“re quite proud of it. With its unique insulating glass units, Henze-Glas makes a major contribution to the possibility of manufacturing large glass faades with the utmost transparency, creating new uses for glass in buildings and state-of-the-art architectonic designs. The company is equipped with a logistic service complete with delivery and on-site assembly of these high-tech glass units by qualified and specialized workers. The sizeable glass units reach the construction site by special company-owned vehicles, where Henze-Glas specialists provide for its professional installation. An important contribution to the production of this insulating glass unit was made by Fenzi, chemical leader for secondary processing of flat glass. Henze-Glas chose Thiover, Fenzi“s top-selling sealant worldwide, as the edge sealant due to its excellent mechanical properties which are capable of maintaining the rigidity of such a large system. These characteristics are further enhanced by Chromatech Plus, the spacer bar particularly suited for large, remarkably complex insulating glass units which is produced by Rolltech, a company which, together with Fenzi and Alu-Pro, forms the International Glass Alliance network.
