Oct 8, 2023 · The R-value of 1 inch of Styrofoam insulation typically falls within the range of R-3.6 to R-4.2. However, it’s essential to note that the specific R-value can vary based on the type and density of the Styrofoam used.
All About Insulation R-Values - The Home Depot
Jul 24, 2024 · An R-value tells you how well a type of insulation can keep heat from leaving or entering your home. R-value insulation ratings vary based on the type, thickness and density of the insulation material. Typically, a higher R-value means better climate control and better energy efficiency for your home. It usually means a higher price point as well.
Rigid Insulation R-Value Per Inch (+ EPS, XPS, ISO ... - LearnMetrics
R-values for rigid insulation vary from R-3.85 to R-6.8 per inch of thickness. Polyiso has the highest R-value, followed by XPS and EPS. The key to all rigid insulation high R-values are small air pockets that exhibit high thermal resistivity properties: Small air pockets visible in Styrofoam.
StyrofoamTM Brand SM Insulation’s closed-cell structure resists water absorption, enabling it to retain a high R-value (RSI)** over time – a necessary property in below-grade residential foundation applications. It helps to protect foundation damp-proofing and waterproofing, especially during backfilling.
