How to Dry Fiberglass Insulation?

First of all, not all of us know exactly what type of insulation we have in our walls. If this is your case, you need to check the wall and floor cavities in your house. Do you see pink batts or loose-fill insulation in them? If you do, it means that your home is insulated with fiberglass.

This insulation material is called like this because it is made of tiny strands of glass, which is why it doesn’t absorb water.

What is needed to make the fiberglass insulation dry faster

However, if moisture gets into the air pockets between the fibers and fills them, the insulation starts losing its ability to slow the transfer of heat. And since water is a conductor, when it makes fiberglass insulation wet, it is about as effective as having no insulation at all!

Is it possible to do something and save your insulation while it’s still not too late? Luckily, it is. To help fiberglass insulation dry out, follow a few easy steps:

  • Get a dehumidifier or fan
  • Place the drying appliance in the area
  • If possible, remove the affected insulation batts and transfer them to a warm place to dry
  • Once they dry out, return the insulation to the wall or floor cavity where it was taken from

When you are drying fiberglass insulation, it is also important to inspect the material once again in the next few weeks. If you sense a funny smell that’s coming from it, this means the fiberglass was contaminated with dirty water.

Should this happen, the affected insulation should be replaced in order to avoid making your indoor air quality worse.

At this point, you might be tempted to do the job yourself, but we would not recommend doing these tasks on your own. The best way to go is to call on a trusted insulation expert to get the job done properly and safely.

How to Dry Cellulose Insulation If It Gets Wet?

If you have cellulose insulation in your home, you will see loose, gray fibers in wall and floor cavities. With this insulation, things are going to be a bit more complicated. See, cellulose is primarily made of recycled newspaper, which makes it a plant-based product. There is no need to say that it can easily get wet and be difficult to restore after being affected by moisture.

What happens if a more durable piece of insulation gets wet

What shall you do in this case? You can use one of two options:

  • If the piece of wet cellulose insulation is small enough, it might be possible for you to remove it. If you can do this, you need to let it dry for a few days and then put it back
  • However, if a more substantial piece of insulation has gotten wet, there is a high risk of mold growth! Mold can start growing within just a few days, so total removal and replacement of damaged insulation might be the only option available

If you are not sure how massive the damage is, you’d better call a professional to examine your insulation and give you a conclusion, as well as further instructions on your actions.

How to Dry Wet Styrofoam Insulation?

This type of insulation is the easiest one to find and recognize! You can easily know your home has spray foam insulation if wall and floor cavities are filled with hard white foam.

But even though spray foam insulation works as a moisture barrier and is able to create an air-tight seal, the leak can still be problematic. See, the problem is that water is more threatening not for the insulation material itself but for the surrounding materials. Water can damage the wood surrounding the insulation, for example.

This is why the first thing that should be done to solve this problem is to find the hole and seal it to protect your home’s porous structures from moisture damage.

Now you know how different types of insulation can be dried. Also, you learned how you can tell the difference between the most common insulation types that are used in our homes. It will help you to figure out what drying methods might be more effective for your insulation type should it get wet.
