Poor attic insulation can cause the following things to happen:

  • Outdoor air flows inside, and indoor air flows outside
  • Higher electricity bills because your HVAC unit has to work harder to maintain your desired indoor temperatures
  • Some health risks and issues
  • Pest infestations

It is best to replace your attic insulation before these problems begin or escalate into something much worse.

Here is a list of the most common types of attic insulation and the length of time they will last before you need to replace your Attic Insulation.

1) Fiberglass Insulation

Fiberglass insulationReplace Your Attic Insulation - Attic Health is affordable and efficient because it is loose-fill insulation with a potential lifespan of between 80 and 100 years.

However, you need to ensure the fiberglass insulation doesn’t get damaged, or it will have a much shorter lifespan.

Some people report sagging in their fiberglass insulation after about a decade, so you should have a professional inspect your attic insulation every year or two.

Then you can have peace of mind knowing if your fiberglass insulation is still viable or not.

2) Cellulose Insulation

Cellulose insulation is an environmentally friendly insulation that effectively prevents air leakage in attics. Some evidence shows it could potentially stop fires from spreading in homes too.

Unfortunately, the average cellulose insulation will deteriorate after about 10 or 15 years. The lifespan may shorten even more if the insulation is subjected to bad weather conditions.

3) Spray Foam Insulation

Spray foam insulation can last longer than any other insulation option because it doesn’t retain water or attract mold.

If it isn’t damaged by pests or bad weather, spray foam insulation could last more than 100 years. It is also an affordable insulation option too.

You should continue monitoring your spray foam insulation and make any necessary repairs that are needed. Then you can avoid replacing it for the rest of your life.

4) Radiant Barrier Insulation

Radiant barrier insulation is a little more expensive than the average type of insulation, but it has many benefits.

It is a barrier with a thin aluminum sheet designed to reflect light and heat from the sun.

After installing a radiant barrier, you could easily maintain a cooler attic during the summertime.

The best part is that the average radiant barrier lasts between 80 and 100 years. Therefore, you shouldn’t need to replace your radiant barrier insulation again.

5) Rock Wool Insulation

Rock wool insulation is a unique insulation material made from actual rocks. It can insulate and soundproof cold attics and other rooms of your home.

Most rock wool insulations will stay strong for at least 30 years. However, some can last up to 80 years, depending on whether they’re well-maintained and the quality of the insulation.
