How Insulation Works

Note the red area on the picture below that shows where the heat is going out from.

thermal image example of housing heat lossHeat 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. The effectiveness of an insulated ceiling, wall or floor depends on how and where the insulation is installed. Let our team at Smart Roofing Systems make sure your job is done right the first time.

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 amount of insulation or R-value you'll need depends on your climate, type of heating and cooling system, and the section of the house you plan to insulate.

Recommended R-value for insulation from the U.S. Department of Energy (www.energystar.gov)
