Hacker Floor Underlayments
Product Benefits: Sound Attenuating

The silence is golden when the gypsum concrete is a Hacker Floor Underlayment.

The challenges of achieving sound reduction in the lightweight structures of today are many. Meeting them is imperative to deliver a high level of acoustic control for interior privacy, not just for residential structures, but any lightweight construction where airborne (IIC) or structural noise transmission (STC) can be an issue.
