How a Radiant Barrier Benefits Your Home

Keeping the heat out of your home during a Texas summer can be a tall order; this is one of the reasons why air conditioning in our part of the country isn’t a luxury, it’s a necessity. Good insulation in Sinton is important in maintaining a cool home during the summer because it slows heat transfer. But there is an additional step you can take to reduce summer heat gain, and that’s installing a radiant heat barrier. Radiant heat barriers are very effective at reducing radiant heat. However, you don’t want just anyone to install one, so call the professionals you can trust: Justice Air Conditioning & Heating.

What Is a Radiant Heat Barrier?

A radiant heat barrier is a reflective insulation barrier that is installed just under the roof of new buildings (or newly-installed roofs) or inside open attic spaces in existing buildings. The barrier consists of large plywood or OSB boards where one side is covered with aluminum sheathing. These boards are installed with the reflective side facing toward the inside of your home and reflect back the radiant heat from the sun. For the sheathing to work properly, the boards need an airspace of at least ¾ of an inch because anything close to them will heat through conduction heat.

Types of Heat

It’s important to understand how heat flows in order to understand how a radiant heat barrier helps:

  • Conduction heat – conduction heat flow is the flow of heat between two materials. An example would be a metal spoon heating up in a cup of hot coffee – the heat is conducted from the hot coffee through the spoon.
  • Convection heat – convection heat is the flow of heat via gases or liquids. Heat moving through air would be an example of convection heat.
  • Radiant heat – radiant heat is heat that travels in a straight line away from any surface and heats anything solid that absorbs its energy.

Benefits of a Radiant Barrier

There are several important benefits to installing a radiant barrier:

  • Can reduce heating and cooling cost
  • Can increase comfort levels
  • Increases energy efficiency
  • Helps keep heat in during the winter
  • Helps keep heat out during the summer
