BIBS insulation, or Blow-In Blanket System, is a type of insulation that involves blowing loose-fill fiberglass insulation into walls or other cavities. Unlike traditional batt insulation that is placed manually, BIBS insulation is installed by professionals using specialized equipment. Once installed, it forms a seamless blanket of insulation that fills every nook and cranny, providing excellent thermal performance and soundproofing. BIBS insulation is particularly effective for insulating walls with irregular cavities or obstacles, ensuring consistent coverage and maximizing energy efficiency.
