Main Content

Knauf Isolator systems are a twin frame metal stud partition system designed to provide fire and acoustic separation between adjacent spaces. Combined with high-performance Knauf plasterboards and Knauf insulation, the systems can comply with Part E and Part B of the building regulations. Performing up to an exceptional acoustic sound reduction of 79dB (Rw). 

* Sound Insulation testing in accordance with BS EN ISO 10140.

** Fire ratings in accordance with BS 476: Part 22: 1987.

*** Maximum heights calculated based on limiting deflection of L/240 at 200Pa and relates to fire resistance in accordance with BS 476: Part 22:1987. For fire ratings in accordance with EN 1364-1: 2015, please contact Knauf Technical Services.

**** Impact Duty rated in accordance with BS 5234: Part 2: 1992 Annexes B,C,D,E.
