What is the sound insulation effect of uPVC Profile?

For a long time, uPVC Profile has gradually gained widespread praise from users due to its super high performance. Among them, its sound insulation effect has been unanimously recognized by everyone. However, some friends who have never used plastic steel profiles may have doubts. How about the sound insulation of the profile, let's explain in detail for everyone:

Generally speaking, the manual of uPVC Profile is written like this: The plastic steel profile has a very good sound insulation effect, which is suitable for residential doors and windows, and is especially suitable for residential buildings in downtown areas. The reason is that the closed cavity structure has a very obvious effect on sound insulation. We can do experiments to prove that the doors and windows of the two rooms are in accordance with the uPVC Profile and the doors and windows of ordinary aluminum alloy materials, and the glass is made of soundproof glass. We set up tape recorders in two rooms, and then went out to make some sounds outside. After testing, we found that the sound of ordinary material doors and windows is obviously greater than that of plastic steel profiles. To be safe, we changed the two doors and windows in the two rooms again, and the test result was still the same as the first one. Through this experiment, the sound insulation effect of uPVC Profile doors and windows is indeed much better. Friends who have not chosen plastic steel profiles can use them with confidence, and they will fully experience its outstanding advantages during use.
