Closed-cell spray foam insulation delivers high energy efficiency through a combination of low air permeability, high R-value, and integrated vapor control. Its dense structure creates a continuous barrier that resists thermal transfer, limits air leakage, and strengthens building envelopes. Closed-cell spray foam’s closed molecular structure contains trapped gas bubbles that slow down heat flow more […]
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 […]
