In commercial multi-family construction, reducing sound between units isn’t just a luxury—it’s part of delivering a code-compliant, comfortable living space. Developers and general contractors are expected to meet stringent building standards while also improving tenant satisfaction. Acoustical flooring systems play a critical role in achieving both.
At Elastizell of Wisconsin, we install gypsum-based underlayments with integrated sound control, which is ideal for apartment buildings, student housing, senior living facilities, and other multi-unit projects. These systems don’t just check a box; they deliver long-term performance, durability, and tenant comfort.
Why Is Acoustical Flooring So Important in Apartment Design?
In multi-story residential buildings, it’s common for tenants to hear footsteps above them or conversations through the floor. These are caused by impact noise (like dropping objects) and airborne sound (like voices or music). Left unaddressed, these issues lead to increased turnover and poor tenant experience.
Acoustical flooring helps prevent this by reducing the amount of sound that travels between units. With the right flooring assembly, including gypsum underlayment, sound mats, and correct installation, developers can significantly improve STC (Sound Transmission Class) and IIC (Impact Insulation Class) ratings across all floors.
These ratings are more than technical jargon. They’re required by code in many cities and states, and are a key part of qualifying for building occupancy and safety approvals.
What Makes Elastizell’s Acoustical Floors Different?
Unlike basic sound mats or post-installation fixes, Elastizell’s gypsum underlayments are designed as part of an integrated flooring system. Benefits include:
- Monolithic Coverage – A smooth, seamless surface ready for finished flooring.
- High Sound Absorption – Helps buildings meet or exceed STC and IIC rating requirements.
- Fire Resistance – A non-combustible system that supports UL fire-rated assemblies.
- Compatibility with Floor Framing Types – Works with wood framing, concrete slabs, or steel deck systems.
- Leveling Benefits – Creates a uniform floor surface, even over uneven substrates.
It’s not just about reducing sound—it’s about building smarter for long-term performance.
Is Acoustical Flooring Worth It for Developers?
Absolutely. For apartment buildings and other multi-unit residential projects, acoustical flooring:
- Protects property value by reducing complaints and maintenance needs
- Improves leasing performance by creating a quieter, more comfortable space
- Helps projects pass inspections by complying with acoustic and fire safety codes
- Reduces rework or callbacks during turnover between tenants
It’s not uncommon for developers to ask if acoustical flooring is really necessary. But when you consider the alternative, tenant dissatisfaction, increased turnover, and retrofit costs, it becomes clear that installing the right system upfront is a smart investment.
