Four Reasons To Insulate Your Crawl Space With Spray Foam

Posted on

When it comes time to replace the insulation in your crawl space, you'll be faced with a decision. Should you simply replace your existing fiberglass insulation with more of the same material, or should you use the new and innovative spray foam? Some homeowners steer clear of spray foam because they don't quite understand how it works or why it's a better choice for their home than fiberglass. Here's a look at four reasons spray foam is an excellent choice, especially for crawl spaces.

Spray foam won't retain water like traditional fiberglass.

In older homes, leaks are common in crawl spaces. If traditional insulation become wet, it not only looses some of its ability to insulate, but also becomes prone to mold growth. Spray foam, on the other hand, repels water. The water will pass straight through the foam so you can clean it up easily and without having to worry about mold.

Spray foam does not sag when used along walls.

If you pack fiberglass insulation between the joists along your crawl space walls, the fiberglass will eventually begin to sag, leaving some areas exposed and uninsulated. You'll need to check the insulation periodically and either add more or try to pull it back up. Spray foam never sags, so you don't have to worry about air gaps. It forms an airtight seal, so your crawl space stays evenly insulated for years to come.

Spray foam does not trap allergens like fiberglass may.

If you regularly use your crawl space for storage, as many families do, you don't want to face a fit of sneezes every time you open the door. Fiberglass can trap pollen and animal dander that blow in through cracks, but spray foam forms a barrier between these allergens and the outdoors, so you can open your crawl space without a worry.

Spray foam won't leave irritating fibers in your possessions.

If fiberglass insulation is disturbed, a shower of small fiberglass particles tend to fall down. These fibers land on the items you're storing in the crawl space, and they cause skin irritation and nasal irritation when you come into contact with them. Spray foam does not give off any soft of residue or budge if you accidentally bump it when shoving a tote into your crawl space.

Spray foam is the most logical choice for insulating most any crawl space. Contact a spray foam applicator or insulation contractor, such as All Weather Shield Inc., in your area, and make arrangements to have it applied to your home, today. Once the foam is in place, you won't have to touch or worry about your insulation for decades.
