How your home loses and gains heat ...

What about the R-Value?

The R-value is derived from a controlled laboratory test of an insulation's resistance to conductive heat flow. All Season's Spray Foam Insulation's R-value is 3.6. But the R-Value is only part of the story and not a sole indicator of how an insulation will perform. The laboratory's measurement does not consider all 3 methods of heat transfer .... Convection, Conduction and Radiation.

Three Methods of Heat Transfer...

1. Convection: The transfer of heat by moving air

Example: Warm air rises in the winter and transfers heat to the ceiling and out to the attic.

2. Conduction: The transfer of heat through a solid material

Example: Heat is transferred from warmer sections of walls to cooler sections.

3. Radiation: The transfer of heat in the form of electromagnetic waves

Example: Heat is transferred from the roof and through the attic to the ceiling an into the structure.

What you do to save on energy costs

For the average U.S. household about half of the energy costs go toward heating and cooling.

• These costs can be reduced by up to 50% by combining the right amount and type of insulation.
  
  
• Using effective air sealing techniques.
  
  
• Install windows that are appropriate for your climate.

  Why Should You Insulate?

  Heating and cooling account for 50 to 70% of the energy used in the average American home. About 20% goes for heating water. On the other hand, lighting and appliances and everything else account for only 10 to 30% of the energy used in most residences. It makes good sense to turn lights and appliances off when they are not needed, and you'll save even more on your energy costs if your reduce the amount of energy needed for heating and cooling.

  Unless your home was constructed with special attention to energy efficiency, adding insulation will probably reduce your utility bills. Older homes are likely to use more energy than newer homes, leading to very high heating and air-conditioning bills.

  Even if you own a new home, adding sprayed foam insulation may save enough money in reduced utility bills to pay for itself within a few years, continue to save you money for as long as you own the home, and increase the resale value of your house.
