Prevent the noise from bouncing to and fro within your home! Installing GreenStuf® Sound Solution Insulation in your walls helps reduce loud sounds. Also known as Quiet Home Insulation or Acoustic Insulation, Sound Solution is the solution you need to stop various noise from sucking out the peace and quiet of your humble abode.

 The addition of Sound Solution® in a standard timber-framed wall will reduce loud sounds on one side to a slight murmur on the other. It reduces airborne sound, impact noise, and noise transmission by controlling resonating noise inside the construction cavity.  

This product can be used in a mid-floor cavity, to significantly reduce noise between upstairs and downstairs. It helps reduce noise from travelling between walls or between floors in your home.



Autex polyester wall insulation batts come in R-values of R2.0 and R2.5, to suit your requirements.

Watch our video for a guide on how to install insulation in your walls in your new build, renovation or extension. 

 IMPORTANT NOTE: Retrofitting wall insulation into your existing home requires a high level of skill. Plasterboards need to be removed and refitted and this is a job for a building expert or highly experienced DIY’er. 

Tips and Tricks:

  • It is important that your wall insulation fits snugly, without protruding from the studs, or leaving any gaps.
  • If you need to trim your wall insulation, follow this video.
  • Use an angle grinder with a really thin metal cutting blade to cut wall insulation batts to the required size.
  • Run the angle grinder steadily along the batt to achieve a clean cut.
  • Cut out sections to allow space for any plumbing or electrical sockets and fittings.
  • Staple double rows of packing straps to hold wall batts firmly in place.
  • For your new home, renovation or extension, ensure all electrical and plumbing work is done first.
  • Ensure no batts stick out in front of studs. This may bow the plasterboard or cause it to pop off the walls before the stud adhesive has cured.
  • Where studs are closer together, batts can be cut to fit.
