In the winter, heat flow moves directly from all heated living spaces to adjacent unheated attics, garages, basements or even to the outdoors. In some cases, heat indirectly transfers through interior ceilings, walls and floors--wherever there is a difference in temperature. To maintain comfort, the heat lost due to cold winter temperatures must be replaced by your heating system. Insulating ceilings, walls and floors decreases this heat flow by providing an effective resistance to heat transfer.

Insulation is rated in terms of thermal resistance or R-value, which indicates an insulation's ability to resist the transfer of heat. The higher the R-value, the greater the insulation's effectiveness. The R-value of thermal insulation depends on the type of material, its thickness and its density. Installing more insulation in your home increases its R-value and subsequently, its ability to resist heat flow.

Smart FOAM Insulation is an effective insulator because of its ability to fill all cavity spaces completely and evenly. Smart FOAM's ability to resist heat flow gives it a higher R-value than both fiberglass and cellulose. This increase in R-value allows you to maintain a comfortable temperature in your home, while saving as much as 30% on your heating bill.
