SBM5 is a heavy layer mineral loaded soundproofing mat nominally 2mm thick with excellent sound insulating qualities which will give significant sound loss improvements to lightweight structures when used as an acoustic membrane. Normally fixed to original panels of metal, wood and plasterboard etc. this acoustic mat is particularly effective at improving the sound insulation value of timber floors and stud partitions. Two to three layers glued onto timber floors will dramatically reduce noise nuisance penetrating the joints of existing flooring. It is very effective as a decoupling layer between plasterboard on ceilings and stud partitions and will often double the sound insulation performance of standard lightweight stud partitions including those annoying low frequencies. When stapled to the underside of ceiling joists before screwing up Resilient Bars, it significantly enhances the sound loss performance of separating ceilings. General Description SBM5 is a mineral loaded heavy layer nominally 2mm thick with a mass of 5kg/m2. It is equal to lead of the same mass in effectiveness and acts as a thin de-coupling sound barrier in stud walls, ceilings and timber floors. Biggest sound insulation improvements can be achieved when it is used as one layer between two sheets of plasterboard. See illustrations below to see how SBM5 Soundproofing Mat can improve the sound insulation of a stud partition.
