Indoor wall with light steel keel and solid single wall which is good?
The proportion of red brick is about 1800kg / m3, the paper gypsum board is light material, the weight is only 1/15 of the same thickness brick wall, 1/10 of the block wall. - so even if the 4-layer gypsum board can not reach the weight of the brick wall.
Cement mortar plaster lightweight block filled with wall insulation performance, to a large extent depends on the wall surface plaster layer thickness. Both sides of the 15mm ~ 20mm thick cement mortar, to achieve good sound insulation effect.
The relationship between the sound insulation and the weight of the partition is logarithmic. When the wall quality is doubled, the sound insulation increases by 6 dB.
Double gypsum board, light steel keel, plus the noise of the light partition wall of the sound insulation effect is much better than a single brick wall, the security is not bad,
But the cost is much higher.
