Overcoming Structural Floor Squeaks in Wood-Framed Construction

Sponsored by AdvanTech® subfloor assembly

Learning Objectives:

  1. Recognize the behavioral characteristics of high performance wood framed floor systems with superior strength and stiffness attributes.
  2. Investigate the multiple components of a wood framed floor system and the ways that they all contribute to improved performance and the elimination of movement and floor squeaks.
  3. Assess the functional contributions of engineered wood subflooring as it relates to structural strength, fastener retention, water resistance, and overall stiffness.
  4. Design and specify wood framed floor systems that perform as intended and reduce or eliminate squeaks that are indicators of other issues.

Floor squeaks are one of the most common homeowner complaints in single-family homes and can be a costly repair in multifamily or light-commercial buildings. A part of a home or building that actively performs all day, every day, it's one of the most important structural interior components of design. While wood-frame floor systems have maintained consistent design standard for years, there remains a persistent issue with squeaks, pops and uneven flooring that may be the result of a combination of sub-par subflooring products or installation. This course discusses subfloor assembly components and the high-performance standards and product innovations from frame to finish that are helping change the quality feel and sound of flooring systems.

Floor squeaks can be a sign of construction problems. Overcoming them and creating a quality finished project requires attention to all aspects of a floor system.


AdvanTech<sup>®</sup> subfloor assembly AdvanTech subflooring exceeds PS-2-code-minimum design standards for strength, stiffness and fastener-holding power. Documented in the ICC Evaluation Service Report, ESR-1785, AdvanTech’s advanced resin technology provides consistent moisture protection throughout the panel, so AdvanTech panels stay flat without swelling, cupping or warping, to give finished floors an even, solid feel. With a higher wood density, AdvanTech® subfloors are the perfect substrate for a variety of flooring applications, including common gypsum-concrete and 2-layer floating subfloor systems in multifamily and light commercial construction.
