Abstract
The invention presents a composite profile for use in the production of windows, doors, facade elements or the like, having inner and outer metallic profiles spaced at a specific distance from each other by a plastic profile. The invention further proposes that the plastic profile contain a surface of a solid, non-porous first plastics material, in a core region, a fine-pored cellular structure of a second plastics material. Additionally, the plastic profile may either be a solid, multilayer profile or a hollow profile. Such plastics profiles are particularly adapted to absorb tensile, bending and/or pressure loads.
Claims23
A heat insulated composite profile having an inner and an outer metallic profile, wherein the metallic profiles are interlinked by a solid or hollow plastics profile-comprising a surface layer of a solid, non-porous first plastics material and a core region comprising a fine-pored, closed-cell cellular structure of a second plastics material, the cellular structure in the core region having an average cell size ranging from 0.005 to 0.15 mm, which keeps the inner and outer metal profiles at a specified distance from each other.
A heat insulated composite profile having an inner and an outer metallic profile, wherein the metallic profiles are interlinked by a hollow plastics profile, comprising a surface layer of a solid, non-porous first plastics material, a core region comprising a fine-pored, closed-cell cellular structure of a second plastics material, and an inner surface layer of a solid, non-porous third plastics material, defining a hollow chamber, which keeps the inner and outer metal profiles at a specified distance from each other.
