At present, we need to do more research and practice in the following aspects on the energy saving of doors and windows. Establish a comprehensive energy-saving index system, such as the window's summer heat transfer coefficient, window glass's shading coefficient, air permeability, and window lighting performance. Establish energy-saving indicators and technologies for doors and windows that are in line with the characteristics of the region; try to increase the thermal insulation capacity of buildings to meet people's requirements for indoor comfort, reduce building energy consumption, strengthen energy-saving technology publicity, and establish a correct national energy-saving concept.

Hardware accessories: Doors and windows rely on hardware accessories to complete the opening and closing functions. It is the most easily worn and continuously active part of building doors and windows. Its functional effectiveness not only directly leads to safety problems, but also affects the insulation performance and watertightness of building doors and windows. Sex and airtightness. Without high-performance hardware accessories as guarantees, it is impossible to produce high-performance energy-saving doors and windows.
Door and window hardware accessories include: handle, sliding support, support gear, handle, window lock, pulley and so on. For the casement window, classification according to the sealing performance can be roughly divided into two categories: multi-point hardware and single-point hardware.
The lock points and lock seats of the multi-spot hardware are distributed around the entire door and window; when the doors and windows are locked, the lock points and the lock seats are firmly buckled together and cooperate with the hinges or the slide stays to jointly generate a strong seal pressing force. The sealing strip is elastically deformed so as to provide sufficient sealing performance for the door and window, so that the window sash and the window frame are integrated; and the single-spot sealing performance is relatively poor. Therefore, the use of multiple locks and window locks can greatly reduce the deformation of the door and window sash and improve the sealing performance. For other accessories, sliding hinges should be made of stainless steel. For sliding windows with a width of more than 1 meter, or doors with double glass installation, double pulleys or rolling pulleys should be used.
Optimize the sectional structure of the door and window frame profile. If there is no corresponding structural cooperation after the emergence of new materials, its role will be limited. The same material used in the structure is different, the difference in performance is very large, such as the use of multi-cavity heat insulation box, sealed with multiple seals and glass, accessories supporting, so that the K value significantly reduced.
From this, it can be seen that to increase the thermal resistance of the frame, it is necessary to increase the width of the heat insulation strip or the thickness of the heat insulation core connecting the inner and outer aluminum frames. In order to make the frame section compact, according to the principle of heat flow length, under the same width of the heat insulation strip, it can be designed as a “bow†shape. Since the length of the heat flow increases, the thermal resistance R is also increased, so that the K value is further reduced.
Multi-cavity heat insulation strip design was adopted to reduce the K value. Renovation's first network reminds that although widening the insulation strip can effectively reduce the K value, it can only be widened appropriately. If it is added too much, it will result in a non-compact structure, and measures must be sought to increase the thermal resistance. According to the principle of heat conduction, the thermally conductive surface can be designed as a superimposed multi-cavity to increase the thermal resistance.
Widening the insulation strip filled with foam material and matching with a multi-head chamber seal to further reduce the K value. In order to lower the K value step by step, the heat insulation strips can be widened, and the foamed material can be filled. The multi-headed seal is used to form the cavity to match the performance.

At the same time infiltration of hardened cement, full penetration reaction, the formation of a hard film on the surface, play a beautiful, conservation effect.
Second, the performance characteristics:
1, to prevent the infiltration of water and gas
2, enhance wear resistance
3, construction is simple, save labor
4, easy to clean
Third, the scope of application:
New cast concrete surface such as: roads, airports, large cement concrete projects, concrete components, wear-resistant floor and so on.
Fourth, the construction instructions:
1, the material should be fully mixed before use.
2, the final surface of the concrete surface after calendering can spray evenly on its surface curing agent,
3, the construction time is about 2-4 hours after calendering (depending on the ambient temperature and humidity at that time) The basic requirement is that the surface has no free water.
4, the concrete facade demolition immediately after the template should be sprayed oily curing agent.
