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…
Read MorePros 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…
Read MoreHigh-Performance Building Case Studies with Foam Board Insulation
The growing emphasis on sustainable construction has pushed building professionals and homeowners alike to adopt more efficient and durable insulation strategies—particularly in retrofit contexts where existing structures must be adapted for 21st-century energy demands. Among the most effective materials in deep energy retrofits are rigid foam board insulations such as expanded polystyrene (EPS), extruded polystyrene…
Read MoreCut Carbon with Reclaimed Foam Panel Insulation
When it comes to making buildings more sustainable, insulation plays a powerful role—not just in how much energy a building uses over time, but in the environmental cost of producing the materials themselves. While attention has often focused on operational energy efficiency, a growing body of research shows that embodied carbon—the greenhouse gas emissions from…
