Our SoundBlocker Quilt is produced using 25mm recycled sheep’s wool on either side of our 2Kg/m2  SoundBlocker Membrane.  This combination gives the product enhanced sound absorbing and sound blocking performance and far better than any other normal mineral wool alternatives creating a far better, soundproofed partition wall.

Because it is up to 4 times more efficient than normal cavity infills due to its unique sound barrier layer sandwiched within the product a superior, soundproofed stud wall can be constructed.

Using this SoundBlocker Quilt system will exceed the requirements of the  Part E Resistance to the Passage of Sound document making it the sensible choice for both new build stud walls and conversion of existing walls in flats.

SoundBlocker Quilt can up rate a normal partition by up to 16dB!

A Greener Solution.

The sound absorbing element of this product is 60% produced using recycled sheep’s wool combined with other recycled and recyclable materials.  So SoundBlocker Quilt has got to be one of the most environmentally friendly acoustic insulation materials used for infilling the cavities of stud walls.   This product does not use for the production or finished product CFC’s, HCFC’s or any gases that could otherwise damge the environment.
