What type of insulation is characterized by sound insulation, non-combustibility, and fire resistance?

Batt insulation is known for its excellent sound insulation properties, which make it an effective choice for improving acoustic performance in buildings. This type of insulation typically consists of fiberglass or mineral wool, both of which have inherent sound-dampening qualities. Moreover, batt insulation is non-combustible, particularly when made from mineral wool, which can withstand high temperatures without contributing to fire spread. This aspect enhances its fire resistance, making it suitable for applications where fire safety is a priority.

In comparison, while rigid board insulation, loose fill insulation, and foam in place insulation offer various thermal performance benefits, they do not possess the same level of sound insulation and fire-resistant characteristics that batt insulation does, making batt insulation a more fitting choice for scenarios where these specific properties are crucial.
