A building material applied as a liquid that expands to fill gaps and cavities, creating a continuous barrier against air movement and temperature fluctuations. This substance is commonly used in residential and commercial construction to enhance energy efficiency and improve indoor comfort. For example, it can be applied in attics, crawl spaces, and wall cavities to minimize drafts and heat loss.
The application of this type of insulation is crucial for maintaining a consistent indoor climate, reducing energy consumption, and mitigating the risk of moisture accumulation, which can lead to mold growth and structural damage. Its adoption represents a significant advancement in building science, offering superior performance compared to traditional insulation methods. This method offers an advantage over traditional methods that rely on the homeowner to ensure proper coverage.
