Ventilated vs Unventilated Crawl Space: What's the Difference?

Before you proceed forward with getting thermal insulation for your NYC homes, what you need to understand is whether your crawlspace is properly ventilated or unventilated. A ventilated crawl space requires insulation within the sub-flooring & between the floor joists; whereas, the unventilated crawl space needs to have an insulated vapor barrier on the ground.

How can you differentiate between the two?

Ventilated Crawlspace

In a ventilated crawl space, there must be vents placed along the foundation walls that are connected to the outside. These vents help in circulating air to avoid moisture build-up & mold growth. The insulation must be installed within the sub-floor & between the floor joists.

Unventilated Crawlspace

In an unventilated crawl space, there are no vents along the foundation walls as they are completely sealed. However, an insulated vapor barrier must be placed on the ground to prevent moisture from coming in. The insulation can be installed on top of the vapor barrier.


If you’re still unsure about which type of crawl space you have, our thermal insulation contractors in NYC can help you out by providing you with the best insulation solution.
