* Approximated ratings above include a hard surface finished floor good. It should be expected that carpet and pad will significantly increase the overall performance of the sound control system. Actual ratings may vary based on project variables. IIC/STC levels above are an approximation of sound reduction potential in a well designed, acoustically sound assembly. Test results are available for the minimum Maxxon Underlayment thickness. This information is based on solid data and years of experience in the underlayment industry, however, due to the many variables beyond our control (for example quality control of drywall installation, type of resilient channel, design and density of the building materials, flanking paths, etc.), it should not be considered a guarantee of performance. For assistance in determining the proper system to meet the requirements of your project, contact your Maxxon Regional Representative at (800) 356-7887 or by using Maxxon's contact form.
