NOTE: Tests with our entire system have not yet been completed in the 25mm size.
Comparing the NRC value of our Polyester with that of Fibreglass leads to the conclusion that our 25mm system with Polyester will meet or exceed the values attained with fibreglass - and much more economically
Always compare “NRC” results that were conducted using type “A” Mounting
