Heterogeneous vinyl is the most common sheet flooring, often used in residential and light to medium commercial spaces. In contrast, homogeneous sheet vinyl is a specialty product made for heavier-duty commercial settings with higher traffic, heavy equipment, and rolling loads.

Heterogeneous and homogeneous sheet vinyl flooring are two different types of vinyl flooring options. Here's a brief comparison:

Heterogeneous Sheet Vinyl Flooring:
- Composition: Heterogeneous vinyl flooring is made up of multiple layers, including a wear layer, printed design layer, foam layer, and backing layer.

- Design Options: Heterogeneous sheet vinyl offers a wide range of design options, including various patterns, colors, and textures. It can mimic the look of natural materials like wood, stone, or tile.
- Durability: Heterogeneous vinyl flooring is known for its durability and resistance to wear, scratches, and stains. It is suitable for both residential and commercial use and can withstand moderate to heavy foot traffic.
- Installation: Heterogeneous vinyl flooring is typically installed using glue-down or loose lay methods, depending on the specific product.
- Maintenance: It is generally easy to clean and maintain heterogeneous sheet vinyl flooring. Regular sweeping, mopping, and occasional polishing can keep it looking fresh and new.

Homogeneous Sheet Vinyl Flooring:
- Composition: Homogeneous vinyl flooring consists of a single layer throughout the thickness of the material. The entire product, including the wear layer, design, and backing, is homogeneous.

- Design Options: Homogeneous sheet vinyl comes in a limited range of designs and patterns, mainly solid colors. It is not intended to mimic natural materials like wood or stone.
- Durability: Homogeneous vinyl flooring offers excellent durability and is highly resistant to wear and tear, making it suitable for heavy commercial use. It is often chosen for high-traffic areas that require long-lasting performance.
- Installation: Homogeneous sheet vinyl can be installed using the full-spread adhesive method. Proper subfloor preparation is necessary to achieve a smooth and even installation.
- Maintenance: Similar to heterogeneous vinyl flooring, homogeneous sheet vinyl is relatively easy to maintain. Regular cleaning, including sweeping and damp mopping, helps to keep it in good condition.

Ultimately, the choice between heterogeneous and homogeneous sheet vinyl flooring depends on your specific needs, preferences, and the intended use of the flooring.
