This document provides information on various sound insulation materials, including their characteristics, pricing, sizes, and intended uses. Glass mineral wool is made from recycled glass, limestone and soda ash to form fine strands that are bound together. It has good tear strength and is lightweight with low environmental impact. Rock mineral wool is made from volcanic rock and recycled slag, and has high compressive strength. It can be used for thermal insulation and fire protection. Foamed plastics like extruded polystyrene are made through an extrusion process and have high compressive strength, water resistance and freeze-thaw performance. Products like Quiet Batt and Studio Pro are high-performance sound absorbing insulation materials used residentially and commercially.
