  • 40kg density mineral wool slabs

  • Ensures the insulation integrity

  • 1200mm x 600mm slabs are ideal for work between stud work or battens

Can potentially provide over 30dB of protection depending on quality of door, and surrounding sound insulation.

This unique flexible edge is produced to ensure a perfect fit is maintained between the product and its supporting framework. This ensures the insulations' integrity.

We recommend the use of easy fit slabs when constructing a hanger ceiling. The mineral wool ensures a great fit between the battens during construction. This tightness of fit is essential when soundproofing a surface. Typically we would recommend 100mm easy fit slabs when removing the existing ceiling. The 50mm variety should be used when keeping the existing ceiling in place.
