Does Insulation Really Help Keep Your Home Cool?


Many homeowners often fail to realize that home insulation is a useful tool for wintertime cold as well as summertime heat. Most people think of insulation as something that keeps them warm; however, it actually does much more. As a thermal barrier, it slows down or stops the movement of heat through conduction and convection. During wintertime, it prevents the heat inside the house from escaping outside. During summertime, on the other hand, it prevents heat from the outside from entering the house, thereby reducing the workload on the air conditioning system.

To understand insulation and energy exchange, watch a cold glass of lemonade sweat on a hot day. As the temperature of the lemonade adapts to that of the room, it gains heat. A home functions in the same way. While one may not observe the sweating process, one will feel a shift in the comfort levels. Home insulation provides a barrier that slows down or prevents the exchange of heat, thereby limiting the energy exchange that affects indoor temperatures.

One of the most common problems homeowners face in relation to insulation is whether they have enough. Installing more can help with the heating and cooling; however, it is important to ensure that other sources of trouble are dealt with by scheduling an energy audit with a certified HVAC technician. Some of the common sources of trouble include:

  • Leaky ducts
  • Unsealed drafts
  • Insufficient insulating material
  • Old equipment
  • Faulty thermostat
  • Improper equipment
  • Unmaintained equipment

Insulating key areas of the home, such as the walls and the loft, creates a great barrier that prevents heat from getting in on scorching hot days. By venturing into the attic on a hot summer day, one can get a good example of insulation at work. Since the attic receives heat from the sun hitting the roof, temperature on a hot day can exceed a punishing 130 degrees Fahrenheit. Without insulation in the attic, that heat would flow down into the house, resulting in a temperature rise.

When it comes to installing insulation, homeowners need to hire professionals who can locate places that need insulation and determine the right type of insulation. Follow us for more great articles on heating, air conditioning and home needs.
