The promotion and application of building energy-saving doors and windows is to choose energy-saving doors and windows that meet the design standards and implementation rules of energy-saving buildings in the region. Energy-saving doors and windows focus on the development and promotion of the following eight technologies:


1.High-performance sealing technology for building doors, windows and building curtain walls


Reduce air permeability heat loss and improve main physical properties such as airtightness, watertightness, sound insulation, heat preservation, and heat insulation. Great breakthroughs have been made in sealing materials, sealing structures and indoor ventilation structures.


2. High-performance insulating glass and economical double glass series products must have a major breakthrough in process technology and product performance


Focus on solving heat reflection and low-radiation insulating glass, high-performance safety insulating glass and economical double glass structure temperature, impact resistance and installation technology, to achieve the scientific combination of heat insulation and effective use of solar energy.

3. Thermal insulation technology for special profiles for aluminum alloy and special profiles for galvanized color plates


Focus on solving the problems of localization of thermal insulation materials and safety of fire resistance and prevention of harmful asphyxiating gases, reduce material costs, and expand the scope of promotion.


4. Development and application technology of special materials for composite doors and windows


Focus on the development of special materials for aluminum-plastic, steel-plastic, wood-plastic composite doors and windows, as well as composite supporting accessories and sealing materials.


5. Door and window type and wall thermal insulation technology


It is necessary to use building energy-saving technology as the driving force to carry out technical transformation and innovation in the window structure, opening form and window structure of our country's residential buildings. Change the single sliding window type and develop casement windows, especially composite inner windows and multifunctional windows. Improve the ventilation function and safety performance of high-sealing windows, and develop luxury aluminum alloy windows with thermal insulation, high efficiency and energy saving, and luxury multifunctional doors.


6. Complete technology for doors, windows and curtain walls


Develop a series of multi-functional, complete sets of products with regional characteristics; make great breakthroughs in improving the quality, variety, and performance of supporting accessories; establish market advantages for products and boutique products; develop diversified, multi-level energy-saving products industrialization Production system.

7. Solar energy development and utilization technology


Building doors and windows and building curtain walls should change the technical concept of passive thermal insulation and single energy saving. It is necessary to combine energy saving with the rational use of solar energy, underground heat (water) energy, and wind energy, and develop doors, windows and curtain wall products that combine energy saving and energy use (using solar energy, cold energy, wind energy, and geothermal energy).


8. Improve the installation technology of doors, windows and curtain walls


Improve the integrated energy-saving technology level of doors, windows, curtain wall structure and enclosure structure, and improve the overall energy-saving effect of the wall. Focus on solving the door and window, curtain wall anchoring and filling technology and the use of solar energy, aerodynamic energy-saving technology.
