Understanding Heat Transfer and eShield’s Role

How Heat Infiltrates Your Home

Preventing heat from exiting and infiltrating your home is essential if you want to keep your energy bills low. In order to properly protect against heat transfer, you must know how it works. By learning the process by which heat transference operates, you can find the best way to combat it. The reason this is imperative is because there is not a single type of heat transfer that affects your home, rather, there are three. The three types you have to understand are conduction, convection, and radiation. Each of these work on different principles and travel through a specific space, which makes guarding against them more complicated than you may think.

The Three Types of Heat Transfer

  • Conduction: Conduction is the process in which heat transfers through direct physical contact. A common example of this is heating a pan on top of your stove. The direct contact between the burner and the bottom of the pan heats the entire surface area of the pan using the burner as a heat source. Fiberglass batts are commonly used to combat conduction because the heat gets caught in the millions of tiny fibers that make up the material. This dramatically slows the process of transference.
  • Convection: This form involves the transference of heat through molecular movement. This takes place when the molecules within an air or liquid rise due to lighter density. They replace the cooler molecules and force them to fall, often back toward the heat source if present. This creates a cyclical process as long as the primary heat source remains present. A common example of this is a pot of boiling water in which the cooler water molecules toward the top are constantly being displaced and forced down by the hot molecules rising. As far as convective heat transfer taking place in the home, it typically happens through the air. This can be combatted with proper caulking and insulating fiberboards.
  • Radiation: This is the transference of heat through electromagnetic radiation. It’s unique in that it doesn’t heat the air or space around it, rather, it only heats objects that it comes into contact with. The object absorbs the heat, which can then be redistributed from there. This can commonly be felt when standing out in the sun or next to a source of light. The heat felt from those sources is radiation. Radiant barrier insulation is the best form of protection from radiant heat transfer.

Installing a Full Insulation System

Most homes in and surrounding areas are equipped with some form of insulation. This may be fiberglass, caulking, or insulating foam boards but they are still getting some protection. However, to create the most energy efficient home possible, you will need to guard against all three types of heat transfer. This includes having the reflective properties of radiant barrier on your side. At Ultimate Gutter Guard of Birmingham, we can help you prepare your home with our eShield® radiant barrier.
