In apartments, hotels, and multi-family housing projects, impact noise โ such as footsteps, moving chairs, or dropped objects โ is one of the most common complaints from residents.
Thatโs why more developers are paying attention to:
๐ IIC (Impact Insulation Class) ratings for flooring systems.
IIC is an ASTM-based rating used to evaluate how effectively a floor-ceiling assembly reduces impact noise transmission.
In simple terms:
โ Higher IIC value
โ Less impact noise heard downstairs
โ Better living comfort
In the U.S., many residential building codes require a minimum IIC rating of 50 between dwelling units.
A customized Protex SPC flooring system has been tested by SGS-CSTC according to:
โข ASTM E492-25
โข ASTM E90
โข ASTM E2179
Test result:
๐น IIC 69 โ exceeding typical residential code requirements.
It is important to note that IIC ratings are measured based on a complete floor-ceiling assembly. Actual acoustic performance may vary depending on the subfloor structure, underlayment, and overall building construction.
For apartment, hotel, and multi-family projects that require a balance of:
โ Acoustic performance
โ Code compliance
โ Commercial durability
a well-designed flooring system plays a critical role.
