R-Value vs. Real-World Performance: What Builders Should Prioritize

R-Value vs. Real-World Performance: What Builders Should Prioritize

R-value is one of the most cited numbers in building construction, often treated as the gold standard for insulation performance. But ask any experienced builder, and they’ll tell you that a high R-value on paper doesn’t always translate to a comfortable, energy-efficient building. That’s because R-value is a laboratory metric—measured under controlled, static conditions that…

How XPS EPS and Polyiso Insulation Perform Against Moisture

How XPS EPS and Polyiso Insulation Perform Against Moisture

When choosing insulation, particularly reclaimed foam panels, one of the most critical performance factors to consider is moisture resistance. Whether you’re working on a foundation retrofit or insulating a roof deck, understanding how insulation responds to water exposure can make the difference between long-term energy efficiency and costly building envelope failures. Moisture resistance determines how…

Pros and Cons of Foam Insulation – Polyiso vs XPS vs EPS

Pros and Cons of Foam Insulation - Polyiso vs XPS vs EPS

Rigid foam insulation plays a critical role in building envelope performance, balancing thermal resistance, moisture management, and structural durability. Among the most widely used materials in this category are Extruded Polystyrene (XPS), Expanded Polystyrene (EPS), and Polyisocyanurate (Polyiso)—each engineered through distinct manufacturing processes that yield markedly different physical and thermal properties. This article provides a…
