Is Blown-In Insulation Safe?

Insulation is a crucial component of any building, as it helps to regulate temperature, reduce energy consumption, and create a comfortable living environment. There are various types of insulation available, and one popular option is blown-in insulation. However, you may be wondering, is blown-in insulation safe? In this blog post, we will explore the safety considerations associated with blown-in insulation.

1. Understanding Blown-In Insulation

Before discussing its safety, let’s first understand what blown-in insulation is. Blown-in insulation, also known as loose-fill insulation, is a type of insulation material that is installed by blowing or spraying it into gaps, crevices, or spaces in walls, attics, or crawl spaces. It consists of loose fibers or small particles made from materials such as fiberglass, cellulose, or mineral wool.

2. Inhalation Concerns

One common concern when it comes to blown-in insulation is inhalation of the insulation material. If the insulation fibers are small enough to become airborne, there is a potential risk of inhalation. Fiberglass insulation, for example, can release tiny fibers into the air during installation or if disturbed. These fibers can irritate the respiratory system if inhaled in large quantities.

However, it’s important to note that modern blown-in insulation products are designed with safety in mind. Manufacturers take precautions to minimize the release of fibers and ensure that the insulation material is safer to handle. Additionally, professional installers are trained to follow proper safety procedures during installation, such as wearing protective gear, using appropriate equipment, and minimizing dust.

3. Skin Irritation

Another potential safety concern is the risk of skin irritation when handling blown-in insulation. Some insulation materials, particularly fiberglass, can cause skin irritation or allergic reactions if they come into direct contact with the skin. It is recommended to wear protective clothing, gloves, and a mask when handling blown-in insulation to minimize any potential skin irritation.

4. Fire Safety

Fire safety is an important consideration when it comes to insulation. The good news is that blown-in insulation is generally considered safe in terms of fire resistance. Most insulation materials used in blown-in insulation, such as fiberglass, cellulose, and mineral wool, are non-combustible or have high fire resistance properties. This means that they do not contribute significantly to the spread or intensity of a fire.

However, it’s important to note that the fire resistance of blown-in insulation can vary depending on the specific product and installation method. It is crucial to choose insulation materials that are tested and certified for their fire resistance properties. Additionally, proper installation practices, such as ensuring airtightness and avoiding contact with heat sources, can further enhance fire safety.

5. Environmental Impact

Environmental impact is another aspect to consider when evaluating the safety of blown-in insulation. Some insulation materials, such as cellulose, are made from recycled materials and are considered more environmentally friendly. On the other hand, materials like fiberglass require significant energy and natural resources for production.

When selecting a blown-in insulation product, it is worth considering its environmental impact, such as its recycled content, energy consumption during manufacturing, and potential for recycling or disposal at the end of its life cycle. Choosing insulation materials with lower environmental impact can help create a safer and more sustainable living environment.


Blown-in insulation is generally considered safe when installed properly and handled with appropriate precautions. Inhalation concerns can be mitigated by using modern insulation products and following safety guidelines. Skin irritation can be minimized by wearing protective gear. Fire safety is ensured by choosing insulation materials with high fire resistance. Lastly, considering the environmental impact of the insulation material can help create a safer and more sustainable living environment.
