Abstract
The Messeturm (“Trade Fair Tower”) in Frankfurt is currently adjusted to the requirements of a modern office building. The lobby area has been enlarged by a highly transparent facade consisting of oversized insulating glass (IG) units. The IG units are curved and have a size of up to 17 m $$\times $$ 2.8 m. To obtain a perfectly curved facade, the IG units were fabricated with laminated cold-bended glass panes. Horizontally the IG units are supported by tapered stainless steel fins. Inclined steel beams connect the top of the facade fins with the tower structure creating a rounded roof. The vertical facade with its glass roof allows maximum transparency for people inside the lobby as well as for people passing by outside to the nearby trade fair grounds. The glass was fabricated by sedak. The facade was installed by seele on behalf of the owner OFFICEFIRST, the asset-management of Blackstone.
