What are the differences between different types of insulation materials?

Different types of insulation materials vary in their properties such as thermal resistance (R-value), fire resistance, moisture resistance, and environmental impact. Fiberglass is a common, cost-effective option with good thermal resistance but can be irritating to the skin and respiratory system. Cellulose insulation is made from recycled paper and has good sound absorption but may be less fire resistant. Foam insulation like spray foam offers excellent insulation and air sealing but can be more expensive and harder to install. Mineral wool is fire-resistant and durable but may be less thermally efficient. Each type has its advantages and drawbacks, and the choice depends on factors like cost, environmental impact, and specific insulation needs.
