Which type of material is NOT typically used for commercial insulation?

Shredded plastic is not typically used for commercial insulation due to several factors. Commercial insulation materials are chosen based on their thermal resistance, fire safety properties, and environmental impact, among other considerations.

Glass wool is widely used in commercial insulation due to its excellent thermal insulation properties and sound absorption capabilities. It is effective for thermal performance, cost-efficient, and light in weight. Wood fiber is also another acceptable option, often used in sustainable building practices due to its eco-friendly nature, providing good thermal and acoustic insulation.

Granulated cork is utilized because it has natural insulating properties and is a renewable resource, making it a favorable option for various commercial applications. It effectively avoids moisture buildup and provides good thermal insulation.

In contrast, shredded plastic does not offer the same level of thermal insulation efficiency, and its environmental impact raises concerns regarding sustainability and recyclability in commercial applications, making it an unsuitable choice for insulation in commercial spaces.
