How to Soundproof your Floor

New Construction Floor Soundproofing

Building a quieter home or commercial property starts beneath your finished flooring. New Construction Floor Soundproofing is the most effective way to reduce airborne noise, impact vibration, and structure-borne sound before the floor assembly is completed. Installing soundproofing systems during construction allows acoustic materials to be integrated directly into the floor structure, delivering better long-term performance than most retrofit solutions.

Florida Soundproofing designs and installs complete REVRB® floor soundproofing systems for residential and commercial construction projects throughout Florida. From acoustic underpayments and Quiet Walk® underlayment to floor joist insulation, Green Glue damping systems, acoustic sealants, and floor isolation assemblies, we create customized solutions that improve comfort, privacy, and building performance.

Installation of a floor soundproofing system

Installing floor soundproofing during new construction provides the greatest opportunity to reduce noise transmission because every component of the floor assembly remains accessible. Rather than attempting to solve sound problems after finishes are installed, our team integrates acoustic materials directly into the building structure for maximum effectiveness.

If your sub floor is already installed, but you want to soundproof the floor, installing our EcoSilent underlayment system along with our Sound Barrier underneath your finished floor, will reduce both airborne and transmission noise.

Floor isolation systems
Sound barrier membranes
Quiet Insul acoustic insulation
Acoustic floor underlayments
Green Glue damping compounds where appropriate
Acoustic sealants around floor penetrations
Isolation clips and resilient components when required

By treating the entire floor assembly rather than relying on a single product, airborne and impact noise are significantly reduced while maintaining structural integrity and flooring performance.

Whether you’re constructing a custom home, apartment building, condominium, hotel, office, or mixed-use development, planning soundproofing before the flooring is installed provides the highest level of acoustic performance and long-term value.

Why Soundproof Floors During Construction?

Installing acoustic systems before the finished flooring is installed offers several important advantages:

Maximum sound reduction performance
Easier installation with lower labor costs
Better STC and IIC ratings
Improved privacy between floors
Reduced footstep and impact noise
Better resale value
Greater occupant comfort

Planning floor soundproofing during construction is almost always more cost-effective than attempting to retrofit noise control after the building is complete.

Understanding Airborne vs. Impact Noise

One of the biggest misconceptions about floor soundproofing is that all noise travels the same way. In reality, different sound types require different acoustic treatments.

Airborne Noise

Airborne noise includes:

These sounds travel through the air before entering the floor structure.

Impact Noise

Impact noise is created by direct contact with the floor, including:

Impact sound travels directly through the building structure and often becomes the biggest complaint in multi-story buildings.

Build a Quieter Floor from the Ground Up

The best time to install floor soundproofing is before the finished flooring goes down. Florida Soundproofing works with homeowners, builders, architects, contractors, and developers throughout Florida to design customized REVRB® floor soundproofing systems that reduce airborne noise, impact vibration, and sound transmission for years to come.

Proper floor soundproofing also helps improve acoustic performance measured by Sound Transmission Class (STC) and Impact Insulation Class (IIC) ratings.

Frequently Asked Questions

What is new construction floor soundproofing?

New construction floor soundproofing is the process of installing acoustic materials within the floor assembly before the finished flooring is installed. By incorporating products such as REVRB® soundproofing systems, Quiet Walk® underlayment, acoustic insulation, and sound barrier materials during construction, homeowners and builders can significantly reduce airborne noise and impact sound for long-term acoustic comfort.

Why should floor soundproofing be installed during new construction?

Installing floor soundproofing during new construction provides easier access to the floor assembly, allowing acoustic materials to be integrated more effectively than after the building is finished. This approach delivers better sound isolation, improves STC and IIC ratings, reduces installation costs, and avoids expensive renovations later.

What types of noise does floor soundproofing reduce?

A professionally designed floor soundproofing system helps reduce both airborne noise and impact noise. Airborne noise includes voices, television, music, and conversations, while impact noise comes from footsteps, dropped objects, moving furniture, and exercise equipment. Combining multiple acoustic products provides the best overall performance.

Is Quiet Walk® underlayment suitable for new construction?

Yes. Quiet Walk® underlayment is an excellent choice for many new construction projects because it helps reduce impact noise, improves walking comfort, and enhances the acoustic performance of floating floors such as laminate and engineered wood. It is often incorporated into complete REVRB® floor soundproofing systems.

Which buildings benefit from new construction floor soundproofing?

New construction floor soundproofing is ideal for custom homes, multi-story residences, condominiums, apartments, hotels, office buildings, healthcare facilities, schools, senior living communities, and other commercial properties where reducing noise transmission between floors improves comfort, privacy, and occupant satisfaction.

What are STC and IIC ratings?

STC (Sound Transmission Class) measures how well a floor assembly blocks airborne sound such as speech and television noise, while IIC (Impact Insulation Class) measures resistance to impact noise like footsteps and dropped objects. Florida Soundproofing designs floor systems that improve both ratings for superior acoustic performance.
