Hi, I am currently fitting a new bathroom and am unsure about the installation method for the acoustic ducting. I had no idea that the inner core is perforated, imagine my shock when I noticed the pin holes!
What I want to know is where do I clamp with the worm clips? Right now I have only clamped the inner core, and now realise that is useless because of the perforations. Do I need to clamp the exterior foil jacket and insulation or just the inner plastic sleeve?
Thanks.
