Which sound insulation effect is better, gypsum board or eco-board?

Relatively speaking, the sound insulation effect of gypsum board will be better. Let's talk about gypsum board!

One: the sound insulation effect of gypsum board itself

Facing the problem of sound insulation effect of gypsum board, let's first look at the sound insulation effect of gypsum board itself. Because gypsum board is made of building gypsum as the main raw material, with a certain amount of fiber and additives wrapped in cardboard, its sound insulation effect is better with the increase of its thickness. Therefore, for some partition walls with low sound insulation effect, thicker gypsum board is used to achieve the purpose of sound insulation.

Second, strengthen the sound insulation effect.

Of course, some people still want to get better sound insulation. In this case, we can add high-density rock wool, glass wool board and so on. To the middle of the gypsum board, or we can add silent treasure environmental sound-absorbing cotton. If these are not enough, we can add 10mm thick pressure cement board and 3mm thick soundproof felt, because the addition of these materials can ensure very good sound insulation effect.

The above is the knowledge sharing about the sound insulation effect of gypsum board, hoping to help everyone.
