How Long Does Insulation Last?

Insulation is a material that is used to reduce the flow of heat, sound, or electricity from one area to another. The lifespan of different types of insulation can vary based on a variety of factors, such as the R rating of the original insulation, compression and movement over time, quality of the material, the installation process, and the environment in which it is used. Here's a breakdown of the general lifespan of different types of insulation:

Fiberglass insulation

This type of insulation can last for 80-100 years, but its lifespan depends on the quality of the material, the installation process, and the environmental factors it is exposed to.

Cellulose insulation

Is insulation made from recycled paper and can last for up to 20-30 years. However, its lifespan may be shortened if it gets wet, as it can lead to mold growth and other issues.

Spray foam insulation

This type of insulation can last for up to 100 years or more, but again, the lifespan depends on various factors such as quality, installation, and the environment.

Mineral wool insulation

This type of insulation can last for up to 100 years or more, making it one of the most durable types of insulation available.

It's important to note that the lifespan of insulation can be affected by various factors, such as moisture, temperature fluctuations, and damage from pests or other environmental factors. Proper installation and maintenance can help prolong the lifespan of insulation and ensure that it continues to provide effective thermal and acoustic insulation.
