UNDERLAYMENT SOUND RATINGS

FOR USE UNDER HARDWOOD, LAMINATE & ENGINEERED FLOORS

FOR USE UNDER LVT, LVP & RIGID CORE

UNDERSTANDING ACOUSTICS

Compression-house

IIC

Measures a floor/ceiling assembly’s resistance to transmission of structure-borne or impact noise such as footfall, or a chair dragging on the floor.

STC

Rates a partition’s or material’s ability to block airborne sound such as a television or people having a conversation.

ΔIIC

The acoustic performance gain between a bare concrete subfloor assembly and a full flooring assembly with underlayment.
