Noise (Snap, Crackle, Pop) (Laminate)

Floor Detective® Claims and Conditions Guide

Summary

Noise in laminate flooring refers to audible snapping, cracking, popping, clicking, creaking, or hollow sounds that occur during foot traffic or load application. Laminate floors are designed to float as a unified system, and sound is generated when components move relative to one another and friction or compression is released. Minor acoustic response or tonal variation may occur in floating systems and can fall within normal system behavior. Persistent, repeatable, or localized noise typically indicates increased movement interaction within the flooring, underlayment, or subfloor assembly. Audible response alone does not independently establish manufacturing nonconformance; origin determination requires correlation of
