Blown-in insulation is an umbrella term for loose-fill insulation blown onto an attic floor, with the two most common types being fiberglass and cellulose. Both types of blown-in insulation offer comparable performance and are composed of recycled materials. However, fiberglass insulation is made up of tiny glass and plastic fibers, which can become embedded in your lungs or skin without appropriate PPE. Blown-in cellulose is safer and will not harm you if you touch it without gloves, but it can be a dusty product. Another type of blown-in insulation is called blown-in dense pack. Liquid foam insulation materials can also be blown into walls, on attic surfaces, or under floors to insulate and reduce air leakage.

What You'll Learn
Blown-in insulation is better suited for attics
Blown-in insulation is a popular choice for attics, and for good reason. Firstly, it is highly adaptable and can conform to any area, making it ideal for tight spaces, irregularly shaped or sized attics, crawl spaces, and walls. This type of insulation can fill every crack and crevice, preventing air leaks, insects, and allergens from entering your attic.
Blown-in insulation is also a faster installation process than other types of insulation. While it requires a certified specialist to install, they will be able to quickly and efficiently blow the insulation into the desired areas, ensuring a thorough job.
Another advantage of blown-in insulation is its ability to provide a high R-value, which measures a material's resistance to heat transfer. The higher the R-value, the more effective the insulation. Blown-in insulation can offer an R38 value, which is towards the upper end of the scale and translates to 14 inches of insulation.
In addition, blown-in insulation can be a more cost-effective option in the long run. While the initial installation may be more expensive than other types of insulation, the higher R-value means it will be more energy-efficient, potentially resulting in lower energy bills.
Finally, blown-in insulation can contribute to a "green construction" project. Using this type of insulation can help a project qualify for reduced permit and inspection fees and even tax breaks in some areas.
Overall, blown-in insulation is a versatile, efficient, and effective choice for attic insulation, offering high R-values, quick installation, and potential cost savings.

Plastic insulation fibres can be harmful to health
Plastic insulation is a popular choice for many homeowners as it is affordable and easy to install. However, plastic insulation fibres can be harmful to health, especially during the installation process.
Firstly, plastic insulation is known to cause skin irritation and rashes. The tiny shards of glass within the fibre can cut the skin, leading to severe itching and irritation. These fibres can also enter the eyes, causing redness, irritation, and swelling. Therefore, it is crucial to wear proper protective gear, including gloves and safety goggles, when handling plastic insulation.
Secondly, plastic insulation poses a risk of inhalation. The small glass fibres can be easily inhaled, leading to potential irritation of the respiratory system and possible exacerbation of existing conditions such as asthma or bronchitis. In rare cases, there are also concerns that inhaling these fibres may contribute to the development of cancer, although this link has not been conclusively proven.
Additionally, plastic insulation has been associated with moisture problems within walls. Improper installation or exterior leakage can result in condensation and, consequently, the growth of mould or mildew. This can have adverse effects on indoor air quality and potentially impact the health of occupants, particularly those with respiratory issues or allergies.
Moreover, plastic insulation has a negative environmental impact due to its low recycling rate. The building industry's extensive use of plastic products and generation of plastic waste contribute significantly to plastic pollution. As a result, there is a growing interest in sustainable alternatives, such as natural fibre insulation materials like cotton, sheep's wool, and rock wool.
To summarise, while plastic insulation offers benefits in terms of cost and ease of installation, it is important to be aware of the potential health risks associated with its use. These risks can be mitigated through proper installation techniques, the use of protective gear, and the consideration of alternative insulation materials with less environmental impact.

Plastic vapor barriers can prevent moisture buildup
Plastic vapor barriers are crucial in preventing moisture buildup in buildings. They act as a protective layer between the insulation and the interior of a building, blocking moisture infiltration and preventing condensation. This is especially important in cold climates, where warm air inside the building can lead to condensation on surfaces, which can then be absorbed into the insulation. This can cause a multitude of problems, including water damage and potential mold growth.
The use of plastic vapor barriers is a standard practice in Canada, where they are installed on the warm side of walls. The plastic acts as a shield, preventing interior moisture from seeping into the insulated walls. However, it is important to note that improper installation of vapor barriers can lead to moisture problems, as it can trap moist air inside the building, affecting its breathability.
To avoid these issues, it is recommended to use reinforced vapor barrier plastic, which offers long-lasting protection against moisture damage. The best insulation vapor barriers are made of polyethylene plastic and are designed to withstand wear and tear. Polyethylene vapor barriers also provide an additional layer of fire protection, enhancing the safety of the building.
The thickness of the plastic vapor barrier is an important consideration. The industry standard is 6 mil, which offers a balance between strength and flexibility, making it suitable for most residential and commercial projects. However, the specific thickness required may vary depending on the intended application, with 2 mil being suitable for temporary protection and 4 mil for general-purpose use.
In addition to preventing moisture buildup, plastic vapor barriers offer other benefits. They help regulate the moisture inside the home, improving air quality. Furthermore, they contribute to energy efficiency by reducing temperature fluctuations, leading to lower heating and cooling costs. Plastic vapor barriers are also essential in protecting the structural integrity of the building by keeping the wood framing, drywall, and insulation in optimal condition.
Overall, plastic vapor barriers play a critical role in preventing moisture buildup and its associated issues. By selecting the appropriate type and thickness of plastic and ensuring proper installation, builders can maintain a safe and healthy environment for the inhabitants while also enhancing the durability and energy efficiency of the structure.
