How to Choose

What Research Says About Underlayment Benefits

Independent laboratory testing and industry standards provide a framework for understanding how underlayment affects floor performance. Acoustic laboratories test impact and airborne sound transmission using standardized methods, while thermal and moisture performance can be evaluated through perm ratings, R-value approximations, and manufacturer testing under simulated conditions. Research and test standards used by manufacturers and building authorities (including ASTM and ISO acoustic protocols and Canadian building guidance for vapor control and energy efficiency) demonstrate that the right underlayment noticeably improves comfort, reduces noise complaints in multi-family buildings, and lowers moisture-related risks when properly specified and installed.

Acoustic performance: Lab tests using standardized methods show well-chosen underlayments reduce impact noise and improve walking comfort; reductions commonly reported in lab settings range from modest to substantial depending on product type and flooring assembly.

Thermal comfort and energy: Underlayment materials with insulating properties can reduce cold-floor sensation and improve the efficiency of underfloor heating systems; performance varies by material thickness and thermal resistance.

Moisture control: Underlayments with integrated vapor retarders or compatible vapor barrier systems reduce the risk of moisture migration into flooring layers and subfloors, which helps prevent mold and adhesive failures in Canadian basements and slab-on-grade installations.

Standards and testing: Acoustic performance is measured with established protocols (referenced in ASTM and ISO standards) and many product claims are supported by third-party lab reports or certification schemes recognized in Canada.

Indoor air quality: Low-VOC formulations and products tested for emissions help meet healthier indoor-air expectations and contribute to green building credits where applicable.
