Yes, open-cell spray foam can make a noticeable difference in reducing outside traffic noise in homes. Its effectiveness comes from its material structure. The foam is composed of millions of tiny, interconnected bubbles that are not fully sealed. This soft, porous texture is excellent at absorbing sound waves, particularly in the mid-to-high frequency range, which […]
Open-cell spray foam is preferred over closed-cell for many interior insulation projects because it offers superior sound absorption, cost efficiency, and structural flexibility in wall cavities and ceilings. It expands more during application, filling gaps and irregular framing more effectively without adding unnecessary weight or rigidity. Closed-cell foam, while denser and more moisture-resistant, often exceeds […]
