Description

Technical Field

[0001] The utility model belongs to the technical field of building environmental protection structures, and in particular relates to an external wall thermal insulation layer structure. Background Art

[0002] The sun shines directly on the building's exterior wall, transferring heat to the interior through radiation and conduction, causing the indoor temperature to continue to rise. In order to reduce the indoor temperature, people usually use equipment such as air conditioners, which not only increases energy consumption and carbon emissions, but also aggravates the urban heat island effect. In addition, long-term exposure to the sun will cause the exterior wall materials to age, affect the appearance and durability of the building, increase maintenance and repair costs, and are not conducive to the sustainable development of the building and environmental protection. Therefore, taking effective insulation measures and green building design can reduce energy consumption, improve indoor comfort, and extend the life of the building, which is in line with the trend of green development and promotes sustainable urban development.
