Project Overview
In multifamily construction, delivering a high-end living experience goes beyond aesthetics—it requires effective sound control between units. At The Piedmont Raleigh, a 382-unit luxury mid-high rise apartment community, achieving acoustic performance without compromising design or construction efficiency was a critical priority.
To meet these demands, the project team implemented Quiet Qurl® 013 MT from Keene Building Products as part of the floor assembly, ensuring enhanced impact sound reduction and long-term performance.
The Challenge
Luxury multifamily developments like The Piedmont Raleigh must balance:
- Acoustic comfort between residential units
- Code compliance for IIC/STC ratings
- Tight floor-to-floor height constraints
- Efficient installation across large square footage
With over 151,000 square feet of flooring, the project required a proven, scalable sound control solution that could deliver consistent results throughout the building.
The Solution
The project team selected Quiet Qurl 013 MT, installed beneath a gypsum concrete underlayment by KMAC of the Carolinas, a licensed applicator specializing in high-performance flooring systems.
Quiet Qurl 013 MT is engineered with Keene’s Muffling Technology (MT), designed to reduce impact noise while maintaining a thin, efficient floor profile—ideal for multifamily construction.
System Benefits:
- Thin profile (~1/8″) for minimal height impact
- Enhanced IIC performance (+5 improvement over standard mats)
- Compatible with gypsum concrete underlayments
- Lightweight and easy to install across large areas
- Consistent, repeatable performance
This system allowed the contractor to maintain design intent while meeting acoustic performance requirements across all units.
Results
By incorporating Quiet Qurl 013 MT, the project team achieved:
- Improved impact sound reduction between units
- Compliance with acoustic performance requirements
- Efficient installation across 150,000+ sq ft
- A thin-profile system that preserved floor height
- Enhanced resident comfort in a luxury environment
The result is a high-performance flooring assembly that supports both the design vision and long-term livability of the building.
