The Methods of Heat Transfer and eShield® Protection

The Many Ways Heat Infiltrates Your Home

Preventing heat transfer in your home is essential to keeping your energy bills at a manageable level. However, basic knowledge of heat transfer is necessary if you want to properly protect against it. Learning which processes of heat transfer are affecting your home the most provides you with excellent insight on the best way to combat it. Unknown to most is that they aren’t battling against a single form of heat transfer but three. These three types are conduction, convection, and radiation. Each of which operate on different principles and travel through a specific space, making them more complicated to stop than you may initially think.

The Three Types of Heat Transfer

  • Conduction: This is the process in which heat transfers via direct physical contact. Conduction can commonly be exhibited when heating a pan on top of a stove. The burner heats the bottom of the pan through physical contact, resulting in the entire surface area of the pan being heated. Fiberglass batts are the most common way to combat conduction, trapping the heat in the millions of tiny fibers that make up the material. This radically slows the process of transference.
  • Convection: This form transfers heat through molecular movement. Convection occurs when the molecules within an air or liquid rise due to their lighter density. These energetic molecules replace the less active, cooler molecules and force them to fall toward the heat source if one is present. This cyclical process remains active as long as the source of heat is present. A pot of boiling water is a great example to show how cooler water molecules toward the top are constantly being displaced and forced down by the rising heated molecules. Convective heat transfer typically takes place in your home through the air. This is typically combatted with proper caulking and insulating foam boards.
  • Radiation: Heat transferred through electromagnetic radiation is referred to as thermal heat transfer, radiation, radiant heat transfer, and several other names. This type of transfer doesn’t heat the air or space around it. Instead, it only heats objects it comes into contact with. The object absorbs the electromagnetically transferred heat, which is then redistributed from there. Radiant heat can be felt when standing out in the sun or next to a source of light. Radiant barrier insulation like our eShield® is the best form of protection from radiant heat transfer.

The Value of a Full Insulation System

Most homes in and surrounding areas have some form of insulation, it may only be fiberglass, caulking, or insulating foam boards but it’s still insulation nonetheless. However, a full insulation system is necessary to completely guard against heat transfer. A full system includes having the reflective properties of radiant barrier installed. At Ultimate Gutter Guard of Greenville, we can help your home’s energy efficiency with our eShield® radiant barrier. To learn more about the energy-saving properties of eShield®, contact us today!
