It can effectively improve the sealing performance of the door and window, prevent external wind, dust, rain and other factors from entering the room, and improve the protection performance of the door and window and the comfort of the room. Secondly, the sealing rubber strip made of flexible material has excellent elasticity and flexibility. In addition, this design also helps to reduce noise and improve the sound insulation effect of the room. At the same time, good sealing performance can also prevent the convection of cold and hot air, improve the heat insulation performance of the door and window, and further achieve energy saving and environmental protection.

[0033] In order to improve the overall sealing of the door, the composite profile door and window 1000 further comprises a glass bead 214, which is arranged on the door sill 12 and located on the same side of the inner door stop 213, and one side of the glass bead 214 abuts against the glass, which can effectively improve the overall sealing performance of the door and window. The sealing rubber strip made of flexible material has excellent elasticity and flexibility, can adapt to the slight deformation of the profile, ensure the sealing effect of the door and window, reduce the loss of energy, and achieve the effect of energy saving. The side of the glass bead 214 facing the glass is provided with a second sealing rubber strip 217, which abuts against the glass to further improve the sealing effect.

[0034] The composite profile door and window 1000 further comprises a third sealing rubber strip 215, and the sealing part 211 is provided with a first mounting groove 211a facing the door sill 12, the third sealing rubber strip 215 is clamped in the first mounting groove, and the third sealing rubber strip 215 abuts against the door sill 12.
