Fiberglass Batts Insulation

Fiberglass has been around since the Model “T” and continues to be widely used for one reason; it is very cheap to purchase. The problem with fiberglass batts is it usually does not do as good a job of insulating. Although once used in most construction, it has now gone the way of the model T. Technology leaped past is years ago.

Spray foam insulation vs fiberglass insulation:

1. Fiberglass insulation fibers can irritate the skin, eyes, and respiratory tract when installed or during removal. Prolonged inhalation of these fibers is considered hazardous, with potential links to respiratory diseases and other health problems.

2. The production process of fiberglass insulation requires significant energy compared to spray foam.

3. There are installation challenges with fiberglass insulation that can lead to gaps and reduced effectiveness of an already inferior insulating product.

4. Moisture accumulation is always a concern with fiberglass insulation. Fiberglass insulation can absorb moisture, which not only reduces its insulation properties but can also lead to mold and mildew growth. This also makes a great environment for rodents, cock roaches, spiders and snakes.

5. Spray foam insulation is much more durable and does not have the settling problem prevalent in fiberglass insulation. When fiberglass insulation compacts at the bottom of walls or attics, its effectiveness requires much more energy to maintain a comfortable house or business.

6. Fiberglass insulation is less effective at soundproofing than spray foam insulation. This is a major concern for many homeowners and businesses close to an airport or freeway.

7. Fiberglass does not have the barrier formation of spray foam. Spray foam insulation expands to fill gaps, cracks, and crevices, creating a continuous barrier. This property makes it difficult for insects and rodents to find entry points into a home or building. Fiberglass, on the other hand, comes in batts or rolls that can leave gaps, making it easier for pests to find their way in and establish nests, which can lead to infestations. Spray foam is a hard, dense material that prevents rodents and other pests from nesting.

8. Spray foam insulation does not degrade at near the pace of fiberglass insulation. Also, spray foam cannot be moved and scooted about. Rodents and snakes can move fiberglass insulation around to make themselves cozy nests while also creating space for small pests to enter.

Doesn’t it make you wonder why anyone would choose fiberglass insulation? Like the straw insulation that preceded it, it is time to move on to a 21st century solution.
