For the past several years, Advanced Flooring Concepts has been standing in the gap between acoustical lab data and the specifications that get written from it. Today we're closing that gap. The Silent Advantage is our free specifier's guide to acoustical flooring for multi-family and hospitality construction — and it's available at no charge to every architect, spec writer, and developer who wants it.
What Is It?
The Silent Advantage is a ~50-page specifier's guide to acoustical flooring, built on 12 certified third-party Intertek tests conducted between 2017 and 2024. Every figure in the guide traces back to a named, dated test report — not to marketing estimates or generic manufacturer claims.
What's Inside
The guide is organized around the questions that actually come up in the specification process, not around a product catalog:
- How acoustics are specified differently by assembly type. An open-web wood truss and a concrete flat-plate behave differently — the guide explains what changes and why.
- The three numbers that matter — not one. Most specifications name IIC. Some name STC. Almost none name HIIC, the impact metric weighted toward the frequencies occupants actually hear.
- Suggested hotel and apartment specs. Specific assembly recommendations tied to certified test data, organized by building type.
- How to read an acoustical test report. What a certified Intertek report actually says, what the numbers mean, and how to use them.
- When the separate sound mat is still the right call. The guide doesn't argue that one method is always correct — it documents the cases, including renovation work, where a separate mat still makes sense.
The Sound Mat Reversal
One of the most important findings in the guide is what happens when you remove the separate sound mat. Recent testing shows that an acoustical LVT with the backing adhered directly under the wear surface can meet — and in some assemblies exceed — the performance of a conventional floor installed over a separate mat below the gypsum.
The implications are practical. The conventional sound-mat-below-gypsum approach requires roughly ten installation steps across multiple trades. An attached-backing glue-down collapses that to a fraction of the steps and a single trade. Deleting a material and a trade has schedule and cost consequences that compound across a 200-unit building.
This is real built work, not a lab curiosity: acoustical LVT of this type has been installed at projects like the Hyatt Centric in downtown Austin, where the financial and schedule case was as compelling as the acoustic one.
Who It's For
The guide is written for the people who decide what goes in the construction documents and the people who have to build to them — architects, spec writers, developers, and contractors. It is not a sales document. The AFC product line appears in the test data because AFC commissioned the tests, but the guidance applies regardless of whose product you specify.
Why It's Free
Because the problem it solves is not a product problem — it's a specification problem. Buildings get built with acoustic assemblies that were never really understood by the person who specified them, and the failure shows up after occupancy, when it's most expensive to fix. The guide is free because it should be.
Specifying a quiet floor shouldn't be a gamble.
