Abstract:

An architectural membrane structure preferably includes an aerogel material disposed, for example, between two outer layers. The aerogel can be in monolithic or granular form or can be present in an aerogel composite. A method for manufacturing an architectural membrane structure includes securing an insert, e.g., an aerogel blanket, composite or granular aerogel, between a first and second layer. The architectural membrane structure can be used as a tensioned panel in envelopes such as roofing, overhangs, canopies or in other architectural or structural fabric applications.

Abstract:

A float system comprised of modular units assembled to form relatively rigid floating assemblies in a plurality of configurations is provided. In a preferred embodiment comprising a basic two-tier assembly, the modular units form upper and lower layers which combine to define a buoyant, protected shell. The units are preferably interchangeable so that they may be used for either the upper or lower layer and are assembled in a staggered manner to form overlapping connections. The modular units may be assembled using a buoyant lower layer and a non-buoyant upper layer, or using more than two buoyant layers if desired. Preferred embodiments for unevenly loaded structures include multilayer portions at locations on the structure corresponding to increased loads.
