Insulation Basics To Help Keep Your Home Cool

Insulation Basics To Help Keep Your Home CoolIf you’re like most San Joaquin Valley homeowners, you’re looking for the best way to block the blistering heat from entering your home. Luckily, by getting to know insulation basics, you can learn how to keep your home cool without spending a fortune on air conditioning. Knowing insulation basics will also help you save energy in the winter.

Here are some of the best types of home insulation for central California homeowners:

  • Fiberglass – This option is one of the most common types of home insulation, and is also one of the best choices for homes in hot climate regions. However, your insulation can suffer gaps that lead to condensation or air infiltration if it’s not properly installed.
  • Cellulose – Because this insulation can be blown in via small holes, it’s great for retrofitting. This is also one of the most energy-efficient options available. The primary disadvantage, however, is that it can sag over time unless installed by an experienced professional.
  • Spray foam – This is one of the most effective insulation options for hot and cold climate regions. Because it starts as a liquid and expands into foam, it fills all gaps and immediately blocks heat flow. The primary disadvantage is that it’s slightly more expensive than other options. However, when it comes to your home, it’s always best to choose quality over price.
  • Reflective/radiant barriers – This insulation option keeps your home cool by reflecting radiant energy, and is one of the best options for hot climates. Generally, the reflective barrier is made of foil with a foam backing. Because it can become a safety hazard if it makes contact with faulty or old electrical wiring, it should be installed by a professional.
