Is There Asbestos In Insulation?

Pink Fiberglass insulation

For a long time, pink or yellow insulation materials were made with asbestos before it was known how dangerous asbestos is. Fortunately, no insulation materials can be made with asbestos today. However, many homes may still have old insulation that should be replaced because it contains asbestos.

It can be hard to tell if your home’s pink or grey insulation has asbestos. In this article, we’ll review the signs that you have asbestos-containing insulation and what you can do about it.

Does Older Insulation Contain Asbestos?

Most of today’s homes don’t have insulation made with asbestos. The main manufacturer of pink asbestos-based insulation stopped using asbestos in 1990. If your home was built after 1990, it’s unlikely to have insulation with asbestos. Most likely, your current insulation is made of fiberglass.

How to Tell if Your Insulation Has Asbestos in It

If you have old insulation and suspect that it may contain asbestos, there are a few things you can do to figure that out.

Consider these factors to determine if you have asbestos:

  • Fluff: The fluffiness of loose-fill insulation can show if there is asbestos. If the fluff resembles a snow drift, you likely don’t have any asbestos. If your insulation feels firm and lays flat, you might have asbestos and should have your insulation replaced as soon as possible.
  • Texture: Asbestos-containing insulation was typically heat-treated, creating an accordion-style texture that gives it a unique look.
  • Color: A lot of asbestos-containing insulation has a gray-brown or silver-gold color. Loose-fill insulation with asbestos tends to have a gray color to it.

Should You Replace Your Insulation?

If you think you have asbestos in your insulation, it’s best to call a professional immediately to schedule replacement. Expert insulation contractors can verify that your home has asbestos-containing insulation and can carefully replace it with safer materials.

There are countless benefits to replacing your insulation, including:

  • Cleaner air throughout your home
  • Reduced risk of respiratory health issues
  • Added value for your home if you intend to sell
  • Easier to safely remodel your home in the future

There are many different reasons a homeowner would want re-insulation services. Calling a professional should be a priority for anyone who has asbestos in their insulation.
