What is Thermal Insulation?
Insulation is defined as a material or combination of materials which retard the flow of heat. The materials can be adapted to any size, shape or surface. A variety of finishes are used to protect the insulation from mechanical and environmental damage, and to enhance appearance. Its efficincy is measured in R-values.

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..

Why Insulate Your House?
Heating and cooling account for 50 to 70% of the energy used in the average American home. Inadequate insulation and air leakage are leading causes of energy waste in most homes.

Insulation:
• Saves money and our nation's limited energy resources
• Makes your house more comfortable by helping to maintain a uniform temperature throughout the house, and
• Makes walls, ceilings, and floors warmer in the winter and cooler in the summer.

Which Kind of Insulation is Best?
This is the most popular question asked when clients inquire about insulation. The "best" type of insulation depends on:

• how much insulation is needed,
• the accessibility of the insulation location,
• the space available for the insulation,
• local availability and price of insulation, and
• other considerations unique to each purchaser.

Whenever you compare insulation products, it is critical that you base your comparison on equal R-values.
