Don’t Use Fiberglass Insulation

Fiberglass insulation is commonly used, yet it’s not an ideal solution for crawl space homeowners. This type of insulation absorbs moisture easily even though the area you own doesn’t have any leaking problem. A situation like this only gives the chances for the fiberglass insulation to get damp.

In this case, the fiberglass will not be able to do the job properly as the wood start to suffer. When this occurs, the damp insulation supports can’t hold up in the attics longer than it should. Therefore,  you can expect the insulation to start sagging.

Besides that, the fiberglass insulation that already gets damp will create a perfect environment for mold to grow. The moisture that was absorbed to the insulations translates into high level of humidity. Mold will risk your family’s health as well as causing the wood to rot.

Once fiberglass insulation is damaged, there is not even a single way would work out to fix them. We only recommend you to remove the fiberglass insulation and switch into the spray foam.

All in all, no matter what type of insulation you choose and wherever it is located, sizing come as a priority. Your insulation can’t be bunched up, compressed down, or even flattened up. By doing this, you forced the insulation to be fitted perfectly.

In other words, you have to keep an eye and take notes carefully when you start measuring them. Please make sure to double-check the quantity as well. Otherwise, you will only find your insulation laying down on the floor.
