What is the density of open cell spray foam insulation?

Open cell spray foam insulation typically has a density that falls around 0.5 pounds per cubic foot. This low density is one of its distinguishing characteristics, allowing for flexibility and ease of application, which are beneficial in many insulation projects. The reduced density also contributes to its energy efficiency properties, as it can expand to fill cavities and seal gaps effectively while remaining lightweight.

In contrast, options that suggest higher densities do not accurately represent the typical characteristics of open cell spray foam. For instance, densities of around 1 pound or more per cubic foot are generally associated with closed cell spray foam insulation, which is much denser and has different properties and applications. Therefore, identifying the correct density of open cell spray foam as approximately 0.5 pounds is critical for understanding its proper uses in the field of insulation and provides insight into its performance attributes.
