[0026] Reference Figures 1-4A soundproof and heat-insulating PVC window includes an inner window frame 1, an outer window frame 3 fixedly connected to one side of the inner window frame 1, a thermal insulation strip 2 embedded between the inner window frame 1 and the outer window frame 3, and a glass body 4 disposed between the inner window frame 1 and the outer window frame 3. Both the inner window frame 1 and the outer window frame 3 are made of high-strength PVC material. The glass body 4 includes transparent glass 401, a vacuum layer 402, and transparent glass 403. Both the inner window frame 1 and the outer window frame 3 have cavities 7 inside, filled with a low thermal conductivity foam material 5. A moisture-proof membrane 6 is disposed inside the cavity 7 and on the side of the low thermal conductivity foam material 5. A sealing strip 11 is disposed at the contact point between the inner window frame 1 and the glass body 4. The vacuum layer 402 in the glass body 4 can effectively block the transmission of sound waves and heat. By using transparent glass 401, vacuum layer 402 and transparent glass 403, the sound insulation and heat preservation performance can be greatly improved, meeting the user's needs for the comfort of the living environment. The setting of the sealing strip 11 can ensure the airtightness of the door and window as a whole, thereby achieving good sound insulation and heat preservation effects. Furthermore, through the action of the low thermal conductivity foam material 5, heat conduction and heat convection can be effectively reduced, improving the heat preservation performance of the PVC door and window and keeping the indoor temperature stable. Moreover, the setting of the inner window frame 1 and outer window frame 3 made of high-strength PVC material can make the window frame lighter and make the installation simpler and faster.

[0027] Specifically, two fasteners 9 are fixedly connected to both sides of the glass body 4. Each fastener 9 has two stainless steel screws 10 inside. The fasteners 9 are connected to the inner window frame 1 by the stainless steel screws 10. The use of stainless steel screws 10 can fix the fasteners 9 on the glass body 4 and the inner window frame 1 to ensure the stability of the structure. The thickness of transparent glass 1 401 and transparent glass 2 403 is 5mm. The inner corners of the inner window frame 1 and the outer window frame 3 are provided with positioning grooves 8 that cooperate with the fasteners 9. The positioning grooves 8 are engaged with the corresponding fasteners 9. The cooperation between the positioning grooves 8 and the fasteners 9 can play a certain positioning role, making the assembly operation between the glass body 4 and the inner window frame 1 more convenient.

[0028] Specifically, the sealing strip 11 is made of EPDM rubber, which has excellent elasticity and weather resistance. The thermal insulation strip 2 is made of PA66 nylon, which has low thermal conductivity and a wide temperature range. A waterproof and breathable membrane 12 is provided at the contact point between the outer window frame 3 and the glass body 4. The waterproof and breathable membrane 12 can further improve the waterproof performance of the doors and windows to make them suitable for humid areas. The fastener 9 has a storage hole inside, and the stainless steel screw 10 is placed inside the storage hole to avoid the exposed stainless steel screw 10 affecting the assembly or daily use.

[0029] Working principle: When installing this door and window, firstly, fix the inner window frame 1 and the outer window frame 3 in the pre-reserved holes in the wall, ensuring the verticality and flatness of the inner window frame 1 and the outer window frame 3. Then, install the glass body 4 inside the inner window frame 1 and the thermal insulation strip 2. Use the sealing strip 11 to ensure the seal between the glass body 4 and the window frame. Finally, use stainless steel screws 10 to fasten the window frame and the glass body 4 together. The use of the positioning groove 8 and the fastener 9 can play a certain positioning role, making the assembly operation between the glass body 4 and the inner window frame 1 more convenient. In actual use... During the process, the vacuum layer 402 in the glass body 4 can effectively block the transmission of sound waves and heat. By using transparent glass one 401, vacuum layer 402 and transparent glass two 403, the sound insulation and heat preservation performance can be greatly improved, meeting the user's needs for the comfort of the living environment. The setting of the sealing strip 11 can ensure the airtightness of the door and window as a whole, thereby achieving good sound insulation and heat preservation effects. Furthermore, through the action of the low thermal conductivity foam material 5, heat conduction and heat convection can be effectively reduced, improving the heat preservation performance of PVC doors and windows and keeping the indoor temperature stable.
