SBM5 Soundproofing  mat is a heavy layer mineral loaded 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 mineral loaded sound barrier mat is particularly effective at improving the sound insulation value of  timber floors  and stud partitions.

Sound Proofing a Floor

First ensure the floorboards are securely fixed to the floor and do not squeak when walked over. If necessary, secure the floorboards with strategically placed screws or angular ring nails. Then use our Acoustic Sealant to fill the joints between the boards and any gaps around the edge of the room. Make the floor as airtight as possible with this method. Then using Sta-Stuk Special Spray Adhesive adhere two to three layers of soundproofing mat to the timber floor. This will dramatically reduce airborne noise penetrating the floor from below or airborne noise penetrating the floor from above. It does not significantly reduce any footfall or impact noise. To reduce impact noise through the floor, have a look at the acoustic underlay we can offer.  Because SBM5 is produced from recycled manufacturing materials, there may sometimes be a ‘rubbery’ smell when the product is first unpacked.  Usually any smell will dissipate within a few days but as a precaution, we advise that a thin layer of polythene is laid over the insulation before the final floor covering is installed to seal in any smells.

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

General Description

SBM5 soundproofing mat 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.





12.5mm plasterboard each

at 600mm centres

Plus one layer of SBM5 and

a layer of additional

plasterboard to one side only

Plus one layer of SBM5 and

One additional layer of

Plasterboard to both sides

2 115 33 1/2 35 39

A 3dB improvement is equal to a 50% loss in the volume of noise using the straight line method!!
