Insulation Types and Properties

The video tutorial covers nine types of thermal insulation used in buildings, including mineral wool, sheep's wool, fiberglass, cellulose, polyurethane, polyisocyanurate, polystyrene, and vermiculite. It explains their unique properties, applications, and benefits, such as fire resistance, eco-friendliness, moisture regulation, and energy efficiency. The tutorial also discusses key metrics like U and R values, and how insulation is applied to different building parts to enhance energy efficiency and comfort.
