What Is Retrofit Insulation?

Do you need to re-insulate your home? If so, you need retrofit insulation solutions. Retrofit insulation is insulation that is installed in an existing home. A good way to lower your energy bills and make your home more comfortable is installing retrofit insulation and making sure your home is properly air sealed. In fact, re-insulation can make your home a lot more energy-efficient and help you save money!

When it comes to installation methods, insulation retrofitting can differ from new home construction insulation, but the materials are generally the same:

Do You Need to Re-Insulate?

First things first—how can you even tell when it’s time for re-insulation? There are a few signs that indicate you need more insulation. You may need retrofit insulation if:

  • Your energy bills have been increasing
  • It’s drafty and uncomfortable in your house
  • Temperatures from room to room aren’t even
  • The AC is running more than normal in the summer

These aren’t all the signs, but they are common ones experienced by homeowners. Of course, you can always talk to a professional insulation company.

You have a number of choices when it comes to the material (or materials) you use for your retrofit insulation job. Essentially, you can use any type of insulation! The type you use will depend on a few factors—like where you need to insulate, etc.—and an insulation company will be able to assess your situation and tell you which type(s) of insulation you need to install, how much you need, and where to install it. You may even need insulation removal if the current material is old or damaged.

If you need to re-insulate the attic, for example, radiant barrier insulation is a good solution, especially in a warm climate like Sacramento. It is installed right under the roof to help your home reflect radiant heat from the sun and keep it cooler and more comfortable (and help reduce your energy bills!).
