摘要

Claim 1:– the components, due to the use of thermally inert material, as well as its construction and arrangement, a u - value (heat transfer coefficient) u of at least [1,5 w / (m²·K)] havecharacterized in that– all of the individual components (with the exception of mechanical connecting parts such as screws, nuts, bearings) a u - value of at least [1,5 w / (m²·K)] or have better. This can be both by the choice of the material (wood, plastics, etc.), the cross-section of the material (hollow chamber profiles) and / or the construction depth of the individual components can be achieved
