Why Insulate? — An Introduction to Insulation

Although insulation is an important part of every building, it is often the least understood. Many people aren’t aware of the many places that energy is lost in a home. As an Owens Corning® Certified Energy Expert® professional, Speedy’s Insulation understands the science behind the building envelope. So, you can turn to us to learn more about the benefits of insulation.

Insulation lays a foundation of energy efficiency for every structure. It is one of the most cost-effective ways to save energy and reduce monthly heating and cooling costs. Averaged across the U.S., weatherization measures such as air sealing and increasing the quality and thickness of attic insulation can reliably reduce energy usage by 12–18%. Deeper building retrofits — like adding insulation to walls, basements, and rim joists and installing higher-efficiency windows — could deliver around 33% energy savings.*

Whether you are remodeling a home or building a new business, there are many benefits of insulation:

  • Increased, more consistent interior comfort all year long
  • Reduced energy usage
  • Lower heating and cooling costs
  • Less wear and tear on HVAC equipment
  • Reduced noise transmission for a quieter space
  • Improved air quality
  • Reduced moisture intrusion
  • Less overall environmental impact

How insulation works 80

How Insulation Works

Heat flows from higher temperature areas to lower temperature areas, creating temperature fluctuation within a space. Insulation wraps your home in a protective blanket, reducing heat flow in order to keep the heat out during warmer months and the heat in during cooler months. Insulation is an excellent noise absorber and helps to reduce sound transmission from both outside and within a home, creating a quieter space with less reverberation. Insulation also allows other energy-efficient components, such as air sealing, to do their job, forming a comprehensive insulating system that helps maintain consistent temperatures and moisture levels, reduce energy usage and increase monthly energy savings.

What is R-Value?

The “R” in R-value stands for resistance to heat flow[cite: 15]. The higher the R-value, the higher the level of resistance and the greater the insulating power[cite: 15]. R-value requirements vary depending on climate and building type[cite: 15].

Below is an example of how R-value relates to the amount of insulation used in a typical attic[cite: 15]. The thicknesses listed are for Owens Corning® PROPINK® L77 PINK® Fiberglas™ Unbonded Loosefill Insulation blown in the attic and not a general rule of thumb for any other brand/type of insulation in any other areas/applications[cite: 15]. We can provide you with the correct amount of insulation for your project[cite: 15].

R-value Minimum Thickness (in)
R-13 4.75
R-19 7.00
R-22 8.00
R-26 9.25
R-30 10.50
R-38 13.25
R-44 15.00
R-49 16.75
R-60 20.00

How Much Insulation Is Enough?

The amount of insulation needed varies depending on location, building type, and materials. You can review this recommended R-Value levels chart from ENERGY STAR. We will work with you to provide the right insulation estimate for your specifications.

Things to Consider When Insulating

  • What type of insulation is being used?
  • Does the insulation meet or exceed local North Carolina building codes and national recommended insulation levels?
  • How effective is the insulation (thermal performance, acoustical performance)?
  • Is the insulation resistant to moisture, fire, and settling?
  • Is the insulation material safe and sustainable?
  • Is the insulation cost-effective?

House Energy Efficiency Breakdown

Think doors and windows are at the top of your heat’s escape plan? Think again! Walls, ceilings, floors, and ducts can account for 90% of heat loss if not properly insulated.

Your House as a System

Though insulation is one of the most essential and cost-effective ways to create overall efficiency, there are many factors to take into consideration. Insulation and air sealing combined with energy-efficient appliances, windows, doors, lighting, and HVAC equipment build a whole-house efficiency system that will prove beneficial throughout the year and for years to come. We can provide an in-home consultation to help you create a plan to address any energy concerns in your household.
