Floor performance: A matter of perception

How a floor system performs, in the eyes (or mind) of someone who occupies that floor, is a very subjective assessment.  One person’s opinion of how it should feel when standing or walking on a floor can differ markedly from another’s.  Besides, industry standards aren’t necessarily helpful since meeting minimum building code design requirements doesn’t … Continued
