IIC 50 is the code floor; IIC 67 is achievable with Treadstone Elite. Impervious mats hold rating over time; foam alternatives lose up to 10 IIC points within 2-5 years under load. Use this page to match product tier to IIC/STC target and budget.
Compressible foam mats lose up to 10 IIC points within 2-5 years. Impervious Treadstone mats hold rating for the life of the assembly. Covers Treadstone Elite and Elite Duo: IIC ratings, mil thickness, and lifecycle cost vs. foam alternatives.
A compressible mat under a gypsum pour loses IIC performance as load increases over time. Uncompressible mats maintain rating. Covers why rigidity matters in assembly design, cure sequence before gypsum pour, and IIC 50 vs. IIC 60 cost split.
Treadstone monofilament mats add 4-8 STC points for airborne noise without adding fire risk. Available in fire-rated assemblies. Covers product data, R-value, assembly compatibility, and cost per SF for multifamily floor builds.
