This scheme looks at the integration of alpolic with (waterproof) fabric.  The alpolic base serves as a frame (U-shaped or C-shaped; U-shape pictured below), which the fabric is pulled over and wrapped around to secure.  The fabric forms the roof (and/or wall) of the structure and splits into strips where it hits the alpolic.  These strips anchor down in various places, clinging to the face of the alpolic and around its edges.  The alpolic face has a faceted system under the fabric-covered areas which give the fabric a triangulated and more spatial form.  Perhaps the exposed alpolic has an additional complex – but separate – system, the bounds of which are defined by the path of the fabric “fingers.”
