sound barrier mats-2.0*1.2 metres

SBM5 is a heavy layer mineral loaded soundproofing mat nominally 2mm thick with excellent sound blocking qualities and will give significant sound reduction through lightweight structures when used as a sound barrier. It is equal to lead of the same mass in effectiveness and acts as a thin de-coupling sound blocker in stud walls and timber floors. Biggest sound insulation improvements can be achieved when it is used as one layer sandwiched between two sheets of plasterboard on lightweight structures. One layer of SBM5 has an insulation value of 24dB Two layers has an insulation value of 29dB Three layers has an insulation value of 32dB The above values are calculated when the sound proofing mat is hung as a curtain. It does not mean this will increase a structure by the same degree of sound proofing but simply proves that the mats are a highly efficient method of improving the sound insulation of stud walls, floors and ceilings. Normally, a 3dB improvement is equal to a 50% loss in the volume of noise depending on where you are standing!!
