Door and window solutions

Warm protection, rain or shine

Europe developed high-performance systematic doors and windows as early as the 1980s, which far surpass ordinary doors and windows in terms of energy efficiency, safety, and comfort. In 2003, the European door and window standard required that the K (heat transfer coefficient) value should not be greater than 1.3. At present, high-performance systematic doors and windows have been basically popularized in Europe, and the market application has reached 70% of the total number of doors and windows, while the average K value of doors and windows in China is about 3.5. According to calculations, d on the existing urban construction area of about 43 billion square meters in China, if the current European door and window standard K value is implemented, it can save 430 million tons of standard coal per year, which is about 20% of China's annual coal production, and the energy-saving effect is significant.

In recent years, with the rapid development of the construction and door and window industries, national policy guidance and people's pursuit of quality of life have greatly promoted the popularization of high-end energy-saving doors and windows and systematic doors and windows in China. High performance doors and windows are a perfect organic combination of performance systems, with characteristics such as energy conservation, environmental protection, safety, and comfort, and their performance far exceeds that of ordinary doors and windows in all aspects. The various components of high-performance doors and windows are indispensable for the performance of the entire door and window system. Corners are the weakest link in energy-saving areas of doors and windows [1]. As one of the main auxiliary materials for high-performance door and window corner bonding and sealing, corner bonding adhesive has a significant impact on door and window structure, service life, safety, and other aspects.

In order to solve the corner problem of aluminum doors and windows and produce aluminum doors and windows that meet performance requirements, an effective method is to use a specially designed corner sealant for doors and windows to bond the corner code or plug-in with the cavity wall of the profile, and at the same time, use a section anti-seepage adhesive to seal the 45 ° section. The corner adhesive mainly plays a role in strengthening and sealing the structure, avoiding the misalignment and deformation of the door and window frame caused by temperature difference and external force deformation. The function of the cross-sectional anti-seepage adhesive is to improve the waterproof and sealing performance of the joint, thereby ensuring the airtightness, heat insulation, sound insulation, dust insulation and other properties of the door and window.
