'We are extremely happy with the results. I decided to trust your recommendations and I am extremely happy with the outcome which has virtually cut out all noise. Although more expensive than normal mineral wool soundproof products I would say it is far better value for money judging by the job it has done. It has been an absolute success.'

Typical Applications

Suitable for non – Loadbearing separating wall applications, for new build or to upgrade existing masonry walls with confidence.

Offers very effective remedial solution where sound flanking down cavity walls has resulted in failure on site.

Can assist with meeting external walls thermal requirements by allowing the use of lighter block work and offering an added U-value performance.

A timber stud application is also acceptable and easily used although the test results were obtained using steel stud.
