Why Use Insulation for Your House?

Heating and cooling account for more than half of the energy used in the average US home. If you have inadequate insulation you will experience air leakage, which is the leading cause of wasted energy in American Homes.


  • saves you money and our limited energy resources
  • helps maintain a uniform temperature throughout your house, which makes it more comfortable
  • makes ceilings, walls, and floors cooler in the summer and warmer in the winter

How Much Money Can You Save?

The amount of energy you conserve will depend on several factors:

  • Size and Shape of Your Home
  • Your Local Climate
  • The Construction of your Home
  • Your Family’s living habits
  • The Fuel You Use
  • The Type and Efficiency of your Heating & Cooling system

Soon, the energy savings will have paid for your installation cost. Energy conserved is money saved. As energy rates go up, you will be glad you added insulation.

How Insulation Works

Heat flows naturally from a warmer to a cooler space. In winter, the heat moves directly from all heated living spaces to the outdoors and to adjacent unheated attics, garages, and basements – wherever there is a difference in temperature. During the summer, heat moves from outdoors to the house interior. To maintain comfort, the heat lost in winter must be replaced by your heating system and the heat gained in summer must be removed by your air conditioner. Insulating ceilings, walls and floors decreases the heating or cooling needed by providing an effective resistance to the flow of heat.

What Is an R-Value?

Insulation is rated in terms of thermal resistance, called R-value, which indicates the resistance to heat flow. The higher the R-value, the greater the insulating effectiveness. The R-value of thermal insulation depends on the type of material, its thickness, and its density. In calculating the R-value of a multi-layered installation, the R-values of the individual layers are added.

The effectiveness of an insulated ceiling, wall or floor depends on how and where the insulation is installed.

  • Insulation which is compressed will not give you its full rated R-value. This can happen if you add denser insulation on top of lighter insulation in an attic. It also happens if you place batts rated for one thickness into a thinner cavity, such as placing R-19 insulation rated for 6 1/4 inches into a 5 1/2 inch wall cavity.
  • Insulation placed between joists, rafters, and studs does not retard heat flow through those joists or studs. This heat flow is called thermal bridging. So, the overall R-value of a wall or ceiling will be somewhat different from the R-value of the insulation itself. That is why it is important that attic insulation cover the tops of the joists and that is also why we often recommend the use of insulative sheathing on walls. The short-circuiting through metal framing is much greater than that through wood-framed walls; sometimes the insulated metal wall’s overall R-value can be as low as half the insulation’s R-value.
