AI Technical Summary
Existing building exterior wall insulation structures are prone to thermal bridging due to their single material and unidirectional heat conduction path, resulting in poor thermal insulation performance and difficulty in maintaining indoor thermal stability and energy-saving performance under complex environmental conditions.
The material employs a multi-layer composite structure, including a rubber layer, a first polyurethane board layer, a heat insulation layer, a second polyurethane board layer, and a rock wool board layer, combined with tree-like ridge strips, an aerogel layer, and a hollow foamed ceramic layer, forming multiple thermal resistance barriers that disrupt heat flow paths and reflect heat radiation, thereby enhancing the tightness and adhesion between materials.
It achieves multiple barriers to conduction, convection and radiation heat, significantly improving the thermal insulation performance of the exterior walls, and enhancing the building's energy efficiency and thermal comfort.
