- An R Value is the measurement of thermal resistance that an object has. R values are given to things like windows, siding, and insulation.
- The higher the R value, the more thermal resistance an object provides but keep in mind that you don’t need the highest R value to achieve the thermal resistance goals you desire.
- Spray foam insulation provides a higher R value per square inch than any other form of insulation
When it comes to ensuring energy efficiency and maintaining a comfortable living environment, insulation plays a crucial role. Insulation acts as a barrier between the interior and exterior of a building. It helps to regulate temperature and reduce energy consumption. One essential factor to consider when choosing insulation is the R value. Not having the right R value of insulation in your home can seriously prevent the effectiveness of the insulation in your home. At Eagle Insulation, we take the R value of insulation seriously so that your home is more energy efficient. Still not really sure what an R value is in Spray Foam Insulation? Below we take a deeper look at what R values are.
What Is An R Value?
The R value, short for “thermal resistance,” is a measure of how well insulation material can resist heat flow. It quantifies the insulation’s ability to impede the transfer of heat from warmer areas to cooler areas. The higher the R value, the greater the insulation’s effectiveness in reducing heat flow.
Recommended R Values By Geography
Different regions have varying climate conditions. This means that the recommended R values for insulation may differ depending on geography. Building codes and energy efficiency standards are typically established to provide guidance on the minimum R values required in different parts of a country. These recommendations are based on climate data and are designed to optimize energy efficiency and comfort.
R Value Of Insulation Required For Durango, Colorado
Durango, Colorado, located in the southwestern part of the United States, experiences a climate characterized by cold winters and mild summers. The recommended R values for insulation in Durango are generally higher than in warmer regions. In this region, the U.S. Department of Energy suggests the following minimum R values:
- Attic: R-49 to R-60
- Walls: R-20 to R-30
- Floors: R-25 to R-30
- Basements and Crawl Spaces: R-10 to R-25
It’s important to note that these values are only recommendations. Depending on factors such as personal preference, budget, and energy-saving goals, homeowners may choose to exceed these minimum values.
R Values Of Insulation
Insulation materials vary in their R values, with some providing better thermal resistance than others. Let’s take a closer look at two common types of insulation and their respective R values.
Traditional Insulation
Traditional insulation materials include fiberglass batts, cellulose, and mineral wool. Fiberglass batts, one of the most commonly used insulation types, typically have an R value of around R-3.1 to R-4.3 per inch. Cellulose and mineral wool have similar R values, ranging from R-3.1 to R-4.0 per inch. These materials can be effective in providing insulation, but it’s important to ensure proper installation and sealing to minimize air leaks that can reduce their effectiveness.
Spray Foam Insulation
Spray foam insulation is a popular option due to its excellent thermal resistance and ability to seal gaps effectively. It is available in two types: open-cell and closed-cell. Open-cell spray foam has an R value of approximately R-3.5 to R-4.5 per inch, while closed-cell spray foam offers higher R values, ranging from R-6 to R-7 per inch. The higher R values of spray foam insulation make it more efficient at reducing heat transfer compared to traditional insulation materials.
As you can see, spray foam insulation requires overall less insulation than traditional insulation because of its higher R value per square inch. Because spray foam insulation uses less overall insulation and does a better job of preventing heat transfer, as well as being water & mold resistant, we highly recommend choosing to use spray foam insulation on your building.
