SoundBlocker Quilt

Technical Information


SoundBlocker Quilt Test Data

Environmental Information

SoundBlocker Quilt+ is compressed packaged soundproofing material that is ideal for installation without the ''itchiness'' that mineral wool gives. Being a recycled product, the quilt contains 60% British wool, 30% recycled polyester and 10% polyester binder with a high-recycled content.

Because the rolls of quilt are compressed, it reduces the environmental impact of transportation by about 50% which is far more efficient than transporting alternative, bulkier forms of mineral wool type sound insulation. Once unpacked, it regains its original thickness to provide excellent thermal and acoustic insulation.

Like all sheep’s wool products, it is longlasting, safe to handle and contributes to a healthier indoor environment by regulating moisture and absorbing harmful airborne substances in the home.

SoundBlocker Quilt+ is not a harmful product and can be installed without gloves or protective clothing, although a dust mask may be required if working in enclosed spaces such as lofts. The quilt can be used in conjunction with a vapour permeable underlay if required to retain the benefits of water vapour absorption and release.  Protect the soundproofing from prolonged exposure to sunlight when unpacked and avoid wetting for extended periods, store under cover and clear of the ground.

SoundBlocker Quilt+ can be cut using a straight edge and a Stanley knife. For more accurate cutting, tightly compress or clamp the insulation beneath a solid piece of timber.
