Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to a prefabricated building thermal insulation wall panel. Background Technology
[0002] When using prefabricated building wall panels, regulating indoor temperature can present challenges with seasonal changes. While these wall panels offer advantages in rapid construction and structural stability, their material and structural characteristics mean the walls may not effectively prevent heat transfer from the outside. Especially in hot summers, high external temperatures can easily penetrate the walls, requiring air conditioning and cooling equipment to operate for extended periods, increasing energy consumption. Conversely, in cold winters, insufficient wall insulation can lead to rapid heat loss, increasing the heating burden and making it difficult to maintain a comfortable indoor temperature. This can result in significant temperature differences within the building, particularly in areas without adequate protective layers, where condensation can easily form on the wall surfaces, leading to mold growth and aging. Furthermore, the long-term exposure to temperature fluctuations can accelerate material aging, affecting the wall panels' durability and ultimately reducing the overall building's lifespan.
[0003] To address the aforementioned issues, we have made improvements and proposed a prefabricated building insulation wall panel. Utility Model Content
