What is a primary benefit of using wool in carpets compared to synthetic fibers?

Using wool in carpets offers the significant advantage of natural insulation. Wool fibers have a unique structure that enables them to trap air pockets, enhancing their thermal insulation properties. This helps in maintaining comfortable indoor temperatures by keeping warmth in during cold seasons and blocking heat in warmer climates. Additionally, wool's natural moisture-wicking capabilities can help regulate humidity levels, contributing to overall indoor air quality.

While odor control, lower prices, and structural consistency are important factors in carpet selection, they do not match the insulation properties that wool provides. Wool can absorb odors to some extent, but synthetic fibers often incorporate specific treatments for enhanced odor resistance. Cost-wise, synthetic options typically have a lower initial expense, and structural consistency varies across both wool and synthetic materials, depending on the manufacturing processes and quality standards.
