R-Value is a measure of insulation’s ability to resist heat traveling through it. The higher the R-Value the better the thermal performance of the insulation.

The R-value is the building industry term [3] for thermal resistance "per unit area." [4] It is sometimes denoted RSI-value if the SI units are used. [5] An R-value can be given for a …

To help you choose adequate insulation, we have summarized the R-values of 51 most common insulation materials (check the insulation R-value chart below).

Understanding R-value and choosing the right insulation for your climate can help lower your energy costs and make your home more comfortable. Our guide explains the factors affecting …

We have listed down the important information in the form of tables, outlining recommended r-value insulation ranges, insulation thickness, and typical materials to consider for each area, …

Nov 22, 2024 · What does R-value mean when it comes to insulation? If the temperatures throughout the home seem inconsistent, you feel drafts near the walls, floors, or ceilings, or if …

Jun 3, 2025 · To find the R-value of an insulating material, you’ll need to calculate its heat-resistance per inch of that material. The material’s density. Density is referring to …

Mar 14, 2025 · Choosing the right R-value can keep your home warmer in winter, cooler in summer, and reduce HVAC costs. This guide breaks down what R-value means, how much …

Installing more insulation in your home increases the R-value and the resistance to heat flow. In general, increased insulation thickness will proportionally increase the R-value.

Jun 23, 2025 · Simply put, the higher the R-value – or the larger the number – the greater a product’s insulating power. As the first standardized method for measuring resistance to heat …
