What is R-Value and How it Impacts Insulation Choice

Spray Foam Insulation Orlando, FL
A lot of property owners remain unaware of just how R-value relates to insulation. Most people know that a good R-value is desirable in any insulating product but at the same time, they can’t tell you why. Just like most products and services you get for your home or business property, it is more ideal to know exactly what it is and how it works. This gives you the opportunity to be aware of whether you're getting the best service, a high-quality product and value for your money.  So what is R-value and how does it impact the kind of insulation you pick for your property?

The more you are aware of R-values important role in picking out insulation the better the choice you will make when it comes finding the right insulation for your situation and needs. That’s the only way to get any type of insulation to work properly for you in the situation where you want to apply it.

What exactly is R-value?

Technically speaking, the R-value is a figure that measures the resistance of the flow of heat through a specific type and thickness of a material. To simplify, it defines how well a material stops heat from traveling from one space to another.

Most people assume that the higher the R-value a type of insulation has the better its resistance to heat flow is. For the most part, this is correct but there are other factors that go into choosing the proper insulation for your needs, too. That’s because heat moves from one area to another in different ways.

These are the four main factors that determine how well a particular type of insulation works to stop the flow of heat:

  • Conduction is what R-value measures. It measures heat transfer through solids.
  • Convection is the process through which heats travels through gases, liquids, air, and water.
  • Radiation is heat transfer in the form of electromagnetic waves in the infrared spectrum.
  • Air Infiltration has to do with how tightly sealed a structure is. It’s the ability of outside air to get into a building through such things as cracks and crevices.

Of all of these heat flow factors mentioned above, only conduction is directly measured by R-value. That’s why it’s important when shopping for insulation that you consider the other 3 factors that stop the flow of heat too. Outside factors such as wind, temperature, and humidity all have their own special way in which they impact the transfer of heat.

Ask an Insulation Professional for Assistance

Since there are more factors than just R-value to consider when shopping for insulation, it’s always best to consult a professional. A professional will consider your individual situation as far as the type of space you are trying to insulate and how hard that type of space is to insulate with other factors acting upon it. With their expertise, they should be able to help steer you in the direction of the best type of insulation for your particular needs.
