Doublewall
Doublewall refers to a design concept in which two walls are arranged in parallel with a gap or insulated cavity between them. This configuration is used to reduce heat transfer, improve thermal performance, and sometimes enhance structural rigidity or acoustic isolation. The term is applied across various industries, including consumer goods, architecture, and industrial storage.
Construction methods vary. The gap can be filled with air to rely on still-air insulation, or evacuated
Applications span several sectors. In consumer products, double-wall designs appear in vacuum bottles, insulated flasks, and
Advantages include reduced heat loss or gain, condensation control, improved acoustic isolation, and increased safety in
