The Problem with Compressed Crawl Space Insulation – And What You Can Do About It

Your home’s crawl space plays an integral role in accessing plumbing, wiring, and more – but unless the space is properly insulated, it can be doing harm to your home’s ability to maintain an ideal temperature. Gaps and crack in this area and its walls can let in air, hurting your indoor air quality and more. But even as you make the decision to improve your crawl space insulation, you have different options to explore and problems to consider. Read on to discover what you need to know before tackling issues with insulation!

Insulation Basics


Insulation is an important feature in any home – and it helps to lower your heating and cooling costs by resisting heat transfer into and outside of your home. Heat will flow from warmer to cooler spaces – so, in winter heat will try to escape to unheated spaces and the outdoors, while in summer, outdoor heat attempts to flow inside your air-conditioned home. Insulation, however, resists that flow of heat – and its ability to do this is rated by the insulation’s R-value, or thermal resistance. How does it do this? Fiberglass insulation, for example, prevents heat from easily traveling through layers of spun glass strands, which aren’t a good heat conductor.

Why Compressed Insulation is a Problem

Over time, your insulation can become flattened and compressed. It might even become moved or damaged from human interference or pests. When this happens, the insulation loses its ability to fully do its job maintaining your home’s temperature. Compressed insulation can have worse performance and a lower R value – meaning less thermal resistance. If you continue to allow compressed insulation to remain in your home – or haven’t checked on how your fiberglass insulation is performing – it could be the cause of problems maintaining indoor comfort.

What You Can Do

When you’re having any problems with insulation – whether in your crawl space or anywhere else in your home – you’ll want to extract the damaged or compressed insulation and replace it with new insulation that will better be able to control the temperature inside your home. However, not all types of insulation are created equal, and when thinking about an area like your crawl space, you’ll want to consider how different forms of insulation work. For example, spray foam insulation can have distinct benefits over traditional fiberglass roll insulation in this area. Spray foam insulation can have a great longevity, be able to repel moisture, and can conform to the space it in sprayed into to block the flow of air and heat inside and outside of your home. This can both improve your HVAC performance as well as block any pests from entering your space. With all this in mind, the benefits of spray foam insulation are clear!
