DIY Guide: Installing Reclaimed Rigid Foam Panels for Basement Insulation
Transform Your Basement with Cost-Effective Reclaimed Insulation Imagine a basement that’s no longer a chilly, damp storage area, but a warm, dry, and comfortable extension of your living space. Picture lower energy bills and the satisfaction of having made a smart, eco-friendly upgrade to your home. This is all achievable with the right insulation, and…
Read MoreR-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…
Read MoreHow 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…
Read MoreResources on Deep Energy Retrofits
Below is a curated list of 20 resources focusing on deep energy retrofits for buildings, with a particular emphasis on foam panel insulation (polyiso, EPS, XPS). All links point to reputable third-party sites—primarily doe.gov or epa.gov. Each entry includes a short paragraph describing the resource, its relevance, and why it’s worth consulting. Where possible, case…
Read MoreLayered vs. Single-Layer Foam Panel Insulation: A Comparative Analysis
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…
