1. Design of Insulated Aluminum Profile

　　In the design of systematic energy-saving doors and windows, the design of insulated aluminum profiles is the core part of the entire design, and the quality of profile section design determines the performance and quality of doors and windows. The principle of insulation is to cleverly combine non-metallic insulation strips (nylon 66) with two cross-sectional aluminum alloy profiles using mechanical rolling to form an insulation profile. In the process of profile section design, the main consideration is the effect of wind load, and the requirements of comprehensive strength, stiffness, and stability are taken into account to optimize the design. Under the most economical section area conditions, the inertia moment I and resistance moment W of the section are maximized. Injecting PU resin, known as the "king of insulation", into the cavity after embedding the insulation strip, prevents the convective conduction of heat and has a more significant energy-saving effect.

2. Gap weatherproof design

　　In order to achieve better water tightness, an equal pressure adhesive is designed using the principle of equal pressure, and a drainage channel is set up on the window frame material to divert rainwater. In order to achieve better air tightness, a sealing strip is installed to prevent air infiltration.

3. Hardware accessories

　　Hardware accessories play a very important role in the systematic design of energy-saving doors and windows. The quality of hardware accessories affects various performance indicators of doors and windows. The repeated opening of doors and windows is achieved by hardware accessories, so choosing high-quality hardware accessories is also crucial. The quality and performance of hardware accessories directly affect the processing quality of doors and windows.

We fully adopt European standard slots in the design of systematic energy-saving doors and windows, combined with specialized hardware components, and connect them properly. The hardware components run smoothly, freely, and flexibly in the profile channel. Can use both imported hardware accessories and domestic accessories to meet different levels of needs

4. Hollow glass

　　The sound insulation performance of systematic energy-saving doors and windows is achieved by insulating glass, and the energy saving of doors and windows is also blocked by insulating glass to block thermal radiation.

5. Design of rubber strip

　　The material selection for the rubber strip is EPDM rubber, which has the advantages of good weather resistance, heat resistance, and good sealing performance. The main considerations for styling design are safety, convenience, and reliability, as well as reliable water and air tightness. As shown in the figure below, the isobaric rubber strip is used for water blocking and the first air tightness; Hollow rubber strip is used for the second air tightness; Tower shaped rubber strips are used to press glass tightly.
