The insulation in your attic works two ways: it keeps you cool in the summer and warm in the winter. Providing and installing quality insulation is just one of the many services The Bosworth Company offers. One of the critical parts of selecting the proper insulation for your home or office is selecting the proper R-Value. In this post, we will explore what that means, and how you can find the correct value for you.

WHAT IS AN R-VALUE

The R-Value is a rating related to home insulation. By definition, it measures how well the thickness of the insulation resists heat flow. As we will learn in this post, the R-Value is important, but it is not the only factor when determining the effectiveness and efficiency of your insulation.

HOW IT WORKS

The primary purpose of insulation is to prevent the spread of heat. Insulation keeps the heat in place whether you want to stay warm or cool. Heat moves around your home in four ways:

  • Conduction 
  • Convection
  • Radiation
  • Infiltration

Conduction is the only factor considered when measuring the R-Value.

A variety of factors dictate how insulation and heat/cooling impact your home.

For instance, there are external factors like wind, humidity, and changes in temperature, and internal factors like air and wind pressure, and the overall quality of an HVAC unit.

APPLICATION

Whether your insulation consists of fiberglass batts (more common in older homes) or loose-fill fiberglass (used in newer homes and buildings), the R-Value has an impact on effectiveness.

At The Bosworth Company, we use loose-fill Insul-Safe III fiberglass insulation. This can be sprayed into the attic area to fill in every crack and crevice to help prevent heat from escaping your home. Schedule an appointment online or call us today at 830-428-2764. It’s worth the call!
