Why is beads used for wall insulation?

Beads, often made from materials like expanded polystyrene (EPS), are used for wall insulation due to their Excellent thermal resistance and lightweight properties. They create an effective barrier against heat loss, helping to maintain indoor temperatures and reduce energy costs. Additionally, bead insulation is easy to handle and can be blown or poured into wall cavities, providing seamless coverage and minimizing thermal bridging. Their moisture resistance also helps prevent mold growth, making them a practical choice for various building applications.
