What are the densities of the two types of fiberglass batt insulation?

Fiberglass batt insulation is categorized into two main types based on their densities, which influences their insulating properties and applications. The densities for these types are significant because they determine the effectiveness and suitability for different insulation needs.

For Type 1 fiberglass batt insulation, a density of 1.5 lb/ft³ provides a balance between thermal performance and ease of handling. This density is typically used for general insulation purposes in residential spaces, as it offers adequate thermal resistance without being excessively heavy.

Type 2 fiberglass batt insulation, with a density of 2.5 lb/ft³, is designed for more demanding applications that may require increased thermal resistance, sound absorption, or fire resistance. The higher density means it's better suited for areas that need a more robust insulation performance, such as walls, ceilings, and floors that are subject to extreme conditions.

In summary, the densities of 1.5 lb/ft³ for Type 1 and 2.5 lb/ft³ for Type 2 reflect their intended uses and performance characteristics, making this choice the most accurate representation of fiberglass batt insulation densities.
