Soundblocker quilt a superior, alternative acoustic infill for cavities of stud walls and improve the soundproofing between joists of floors and ceilings


SoundBlocker Quilt is an improved version of our past mineral wool quilt due to being manufactured using recycled sheep’s wool so is not only environmentally more friendly but much better to handle without the itchiness that mineral wool gives.

SoundBlocker Quilt is a superior alternative to the more normal mineral wool that is often used in the cavities of stud walls and timber joisted floors and ceilings and is also up to four times more efficient at blocking airborne noise nuisance from neighbours.


  • Superior to normal mineral wool infill for stud walls and joisted floors
  • More pleasant to handle
  • Uses recycled materials
  • Thermally and acoustically better than mineral wool
  • Produced using naturally sustainable products

Our new SoundBlocker Quilt is equally as efficient at blocking noise as the old product produced using mineral wool but due to its new sound absorbing element of sheep’s wool is not only thermally more efficient but much better to handle.  It’s superior qualities are due to there being a sound barrier membrane sandwiched in the middle that helps block noise whereas the wool element absorbs the reverberant noise found in uninsulated cavities.  This is what makes it a better product to use when looking to achieve the best soundproofing results when upgrading a stud wall, floor or ceiling.


“We could not afford to lose 75 mm using mineral wool on our wall. The SoundBlockerQuilt was the product for us as it only took up 50mm and performs far better.”                                                                                                                                                                                                                                                                                                                  Gloria Turner – Blackpool


SoundBlocker Quilt is made up using 25mm sound absorbing sheep’s wool on both sides of a 2kg/m² sound barrier membrane.  Because of this unique formulation the product out performs normal mineral wool acoustic infills and is the preferred product to use when looking to achieve the very best level of noise control through a structure.

SoundBlocker Quilt can uprate a typical 12.5mm plasterboard clad stud wall by up to 16dB when used instead of mineral wool as the acoustic infill!
SoundBlocker Quilt can also uprate the sound proofing of  a timber joisted floor by up to 13dB when used instead of mineral wool as the acoustic infill!!
