Abstract
Description
Technical Field
[0001] This utility model relates to the field of system window technology, and in particular to a high-efficiency energy-saving system window thermal insulation strip. Background Technology
[0002] Current aluminum alloy door and window profiles rely on a central nylon thermal break strip for insulation. However, the air gap between these strips allows for air convection, making it a weak point in energy efficiency. In traditional structures, the thermal break strips are separated only by an air gap, which allows for heat transfer and reduces the window's insulation performance. Furthermore, existing thermal break strip connection structures often use simple fixing methods, resulting in insufficient structural stability and difficulty in adapting to automated production. For example, conventional anchor bolt arrangements can lead to direct contact between the thermal break strips, creating thermal bridges, and the filling material is prone to cracking due to structural deformation, affecting long-term insulation performance. Therefore, there is an urgent need for a new thermal break strip structure that can effectively block heat convection, improve structural stability, and facilitate mass production.
