Rigid insulation panels

If you’ve ever stood in a lumber yard comparing different types of rigid foam insulation, you know that the choices can be overwhelming. One of the most common points of confusion we see revolves around two terms that are often used interchangeably: “air barrier” and “vapor barrier.” While they might sound similar, they perform fundamentally…

Tiny homes, RVs, and mobile offices are redefining the way we think about comfort, efficiency, and sustainable living. But living small brings unique challenges when it comes to insulation. With limited wall thickness, variable climates, and mobility, choosing the right insulation materials and techniques is critical to maintaining comfort and reducing energy costs. Why Insulation…

It’s More Than Just Foam When selecting rigid foam insulation, the panel’s surface—whether it’s foil-faced or unfaced—is as critical to performance as the foam core itself. This single design choice dictates how the panel manages moisture, heat, and air, fundamentally changing its role within a building assembly. This article moves beyond a simple R-value comparison…

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…

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…

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…

This article compares two common methods for continuous insulation (CI): layered foam panel insulation versus thicker single-layer foam insulation. By evaluating their advantages, disadvantages, and performance characteristics, building professionals and homeowners can make informed decisions regarding insulation strategies. Green Insulation provides reclaimed foam panel insulation throughout New England, helping builders and homeowners save energy, reduce…

Reclaimed foam insulation is gaining traction as a sustainable and cost-effective solution for enhancing building energy efficiency, particularly in cold climates where effective insulation is paramount. Understanding the thermal performance of various foam insulations, especially concerning thermal drift, is crucial for making informed decisions in these environments. For high-quality reclaimed foam insulation solutions, including XPS,…
