(OP)
Acoustical study of industrial process buildings recommend to have NRC (Noise Reduction coefficient) value =0.75 for Pre-engineered Metal Building Walls and Roofs.
I could not find what would be the value of NCR for Standard metal building walls and roof system- Inside and outside liner with insulation.
Please share detail for Pre-Eng Metal building that meets NCR-0.75. Seeking for more references for NCR values of Pre-Eng building wall and Roof sections.
Thank you in advance for your valuable input.
