What materials are included in the category of wood, plastics, and composites?

The category of wood, plastics, and composites includes materials that are primarily derived from organic sources, specifically wood products and engineered materials. Heavy timber is a notable example in this category because it comprises solid wood pieces that are larger than standard lumber dimensions and are often used in structural applications for their strength and aesthetic appeal.

Heavy timber is recognized for its durability, versatility, and thermal insulation properties, making it a preferred choice in various architectural and construction scenarios. This material can also contribute to sustainable building practices, as it is a renewable resource when sourced responsibly.

The other options do not fall into the same category. Structural metal studs are made from steel, which is a metal; glass blocks are made from glass, a non-organic material; and brick is made from clay or concrete products, which do not fit the criteria of wood, plastics, and composites. Therefore, the categorization is based on the nature and origin of the materials.
