Noise Coming Through Walls


Introduction

 

Domestic Sound Insulation

We've all experienced noise coming through walls – TVs, hi-fis and raised voices. Noise that comes through walls can disturb our sleep and generally make life a misery. Obviously, this kind of noise tends to come from apartments, terraced and semi-detached properties.

 

On the other side of the fence, you might have a noisy hobby, such as a musical instrument, and might want to stop noise coming though your own walls into next door. Or you may want to stop noise coming from other rooms in your own home.


Fortunately, there is a solution to noise coming through walls. At SRS, we can fit an independent wall lining of our acoustic building board, Maxiboard. You can then decorate this, just as you would plasterboard, to match your existing room. Maxiboard is a highly effective solution for noise coming through walls, and adds only around 6cms to your existing wall thickness.

Existing Masonry & Timber Stud Wall Treatment

Products required: Maxiboard; SRS Gripfix; SRS Acoustic Sealant; Maxi Resilient Bars; Mineral Fibre Slab; Maxi HP Screws.

Tools required: Tape Measure; Sealant Gun; Circular saw, Jigsaw or Hand saw; Electric Drill/Screwdriver; Step Ladders; Trimming Knife.

Method*:

 

Fix Maxi Resilient Bars horizontally at 600mm centres right across the masonry wall or exposed timber studwork. Put mineral fibre slab between the bars, and screw the Maxiboards to the resilient bars. Place a bead of SRS Gripfix along the edge of each board. Remove the shiplap edge where Maxiboard abuts a wall, floor or ceiling, and place a bead of SRS Acoustic Sealant along the cut edge. Overboard the Maxiboard with a layer of 9.5mm wallboard and a skim coat of plaster. Then decorate to taste.

NOTES:

  • Be careful that no screw fixings penetrate through the resilient bars, and touch the existing wall or studwork.
  • For better performance, install a fully independent wall lining: typically 50mm deep metal or 75mm deep timber stud framework, not in contact with the existing wall; 50mm thick mineral wool slab (45kg/m3) infill to frame; one layer Maxiboard fixed to frame; acoustic sealant to perimeters; one layer plasterboard fixed to Maxiboard to carry skim or taped finish; Typical overall depth 85-90mm.
  • Continue the Maxiboard through the existing plasterboard where adjacent walls are drylined with plasterboard on dabs. Meet and seal with the solid wall behind.

If none of the above fits the issues you're having with noise coming through walls, or maybe you have a more bespoke or specialised construction, don't worry. At SRS Ltd, we've got vast experience in these sort of ‘bespoke’ applications. Just drop an email to one of our technical team outlining your situation and we'll send you a bespoke specification. Or give us a call on 01204 380074 – we're always happy to chat about soundproofing.
