Dear All. I am looking for a little advice. I purchased some insulation products from my local merchant which I was told would be perfect for my room, the purpose of the insulation in acoustical. However, I fear that I may have been mislead or I am simply not installing the product correctly and could do with some advice from an experience professional. I have found the product on eviee's website - http://www.eviee.co.uk/Crown-FrameTherm-Slab-38.htm- any advice anyone can give me would be greatly appreciated.
