Insulating a Crawlspace of an Old Home: What to Know

October 20, 2022

If renovating an older home, you may consider insulating the crawlspace. It is a great idea, but there are a few things you need to know to do it properly. When done correctly, you can help keep the house warm in the winter and cool in the summer. By doing this, you also help reduce your energy bills.


How to Insulate a Crawlspace


There are a few different ways to insulate a crawlspace, but one of the most effective is to use spray foam insulation. This type of insulation can be applied to the walls and ceiling of the crawlspace, creating a barrier that will help keep the temperature inside the crawlspace consistent.


Another option is to use fiberglass batts or rolls. These can be installed between the crawlspace floor joists, and they will also help insulate the space.


Whatever type of insulation you choose, it's essential to ensure that the crawlspace is well-ventilated. That will help prevent moisture buildup, which can lead to mold and mildew growth.


If you're not sure how to insulate your crawlspace, you can always hire a professional insulation installer to do it for you.
