Class A: Organic thermal insulation system, which adopts thermal insulation strips made of organic composite thermal insulation materials with thermal conductivity not greater than 0.3 W/(m*K) and installed in the keel of curtain wall, with ordinary thermal insulation function.
Class B: inorganic thermal insulation system, which adopts thermal insulation blanket made of inorganic composite thermal insulation material with thermal conductivity not greater than 0.02W/(m*K), and is installed in the keel of curtain wall, with high-efficiency thermal insulation function.
2. The birth and development of two curtain wall insulation systems.
In the last century, two kinds of thermal insulation technologies, casting and threading, were born in the world. After decades of development, an organic thermal insulation system has been formed, which is represented by polyurethane casting type of Azon company in the United States and polyamide nylon threading type of Technoform company and Schueco company in Germany. Until the end of 20 14, almost all curtain wall insulation systems in the world were based on this technology.
At the beginning of this century, high-performance inorganic thermal insulation materials for buildings have been initially developed. In 2007, the first generation products were first used in civil construction projects in the United States, and relevant data were collected for testing and formula adjustment. At the beginning of 20 15, the inorganic composite curtain wall insulation blanket material was successfully applied to super-high-rise curtain wall buildings for the first time in China through the systematic design of Warmframe company adopting mature technology and related patented technology. This curtain wall insulation system is also called warm frame system. By the end of 20 19, Warm Frame Technology Co., Ltd. has successfully provided warm frame system solutions, thermal testing of related systems and engineering quality assurance services for more than 400 landmark curtain wall buildings in more than 25 central cities around the world. At this point, a new generation of high-efficiency inorganic insulation system represented by the warm frame system of warm frame technology company has gradually formed.
What is more striking is that the market performance of high-efficiency inorganic thermal insulation system is eye-catching, and at the same time, due to its excellent performance in greatly reducing building energy consumption, the building projects designed and used inorganic thermal insulation system in 20 18-20 19 almost won all the important awards of green energy-saving innovative buildings in Asia, including Bree Am Awards 2065438, Asian Green Building Award of the Year. 20 18 sustainable architecture award; 20 18 Asian Innovative Green Building Award; China 20 18 Times Innovation Award; BREEAM, the first office building in China, with four-star certification; BREEAM four-star certification of the first residential building in China; LEED and Weir Building, Double Gold Certified Office Building and many other award-winning projects.
At present, organic insulation system and inorganic insulation system have gradually become two parallel curtain wall insulation systems in the world.
3. The main differences between the two insulation systems
The innovation and development of new materials and new technology is undoubtedly the main driving force to promote the upgrading of curtain wall insulation system. In addition, the thermal insulation performance of inorganic composite curtain wall blanket material itself is 10 times higher than that of polyamide-nylon thermal insulation strip, which opens a window for curtain wall energy saving and building external wall design freedom.
The technical feature of inorganic thermal insulation system (warm frame system) of Warm Frame Technology Company is that designers use the ultra-low thermal conductivity of inorganic composite thermal insulation materials and the flexible design characteristics of curtain wall thermal insulation blanket, and by blocking heat conduction, convection and radiation at the same time, the heat transfer coefficient (U value) of curtain wall is greatly reduced, so that the energy-saving performance of curtain wall is improved by 30%, and the risk of dew condensation on cold and hot bridges of curtain wall is completely solved. Because the curtain wall structure of warm frame system is simpler and more compact, the use of aluminum strip and high-specification glass is reduced, thus the comprehensive cost of curtain wall is greatly reduced.
In addition, what is even more amazing is that curtain wall designers and constructors found that the new generation of warm frame system adopts carpet-like high-performance inorganic materials with high processability, which is completely different from the organic material characteristics of the previous generation of polyamide-nylon insulation strips, thus bringing ultra-high aging performance with a service life of 50 years, which is almost the same as that of buildings. At the same time, it breaks many designs of traditional organic heat insulation strips, such as high temperature resistance, moisture deformation resistance, structural stress safety and poor flame retardancy.
