Abstract: In order to provide a thread (4, 5) for producing fabrics (2) for insect screens (1), comprising a core, the core having a coating (11) which comprises a heat-activatable adhesive for integrally bonding to itself or to other threads of the fabric (2), and said core having a higher melting point than the adhesive, to provide a fabric (2) for insect screens (1) with a stitch/web structure (7), comprising warp threads (4) and weft threads (5) which are interconnected at node points (6) by means of adhesives, to provide an insect screen (1) comprising a frame (3) and a fabric (2) which is clamped by means of the frame (3), and to provide a method for producing fabrics (2) for insect screens (1), comprising the steps of a) providing threads (4, 5) as warp threads (4) and weft threads (5), b) weaving a fabric (2) using the warp threads (4) and weft threads (5), and c) heating the fabric (2) to a temperature that is higher than the melting point of the adhesive and lower than the melting point of the core so as to c

Abstract: A pyramidal-shaped living structure, having a triangular base plan, includes a pyramidal-shaped solar heating unit which forms the apex of the living structure. The heating unit contains a heat conducting chamber having a transparent wall. Solar rays enter the heat conducting chamber and impinge upon heat conducting elements disposed therein. The heat conducting elements absorb the heat energy in the solar rays causing the temperature of the elements to rise. The elements in turn heat air contained within the chamber. The heated air is then distributed to the interior of the living structure or to a subterranean heat exchange and storage unit, where the heat is extracted from the air and stored for use within the structure during those periods when there is not enough solar energy available to produce the heat required in the living areas.
