Plastic bags are not a good option for insulating walls due to their lack of breathability, which can lead to mould and condensation issues. They are also flammable and break down over time, releasing harmful chemicals. While some people suggest using plastic bags as a creative way to recycle them, it is not worth the potential health and safety risks. There are many other effective insulation materials available, such as fiberglass, rock wool, and foam boards, which are designed to resist heat flow and provide proper ventilation.

Plastic bags are flammable and non-breathable, which can lead to mould issues
Plastic bags are not suitable for insulating walls as they are flammable and non-breathable, which can lead to mould issues. While some people have suggested using plastic bags as insulation by layering and bonding them together, this is not recommended due to the safety and health hazards it poses.
Firstly, plastic bags are made of flammable materials, and in the event of a fire, they could easily catch and spread the fire. This is a significant safety concern, especially for homes. Additionally, plastic bags are not designed to be long-lasting and will break down over time, becoming brittle and falling apart. This means that they would not be effective as a permanent insulation solution.
Secondly, plastic bags are non-breathable, which can lead to moisture buildup and mould issues. Mould can grow and spread quickly in enclosed, non-breathable spaces, posing serious health risks to occupants. Mycelium insulation is an emerging alternative that uses spent mushroom substrate to create biodegradable, breathable, and fire-resistant insulation.
Furthermore, plastic bags can off-gas as they degrade, releasing potentially harmful chemicals into the indoor air. This can negatively impact indoor air quality and the health of occupants, especially over an extended period. It is worth noting that even if mould is not a concern due to a dry climate, a breathable wall assembly is still desirable to ensure proper ventilation and indoor air quality.
While using plastic bags for insulation may seem like an innovative idea, it is important to prioritize safety, health, and long-term effectiveness. Commercial builders are unlikely to consider this method due to the time and potential hazards involved. However, individuals building their own tiny homes may explore this option with careful consideration of the risks and regular monitoring for any signs of deterioration or mould growth.

Plastic bags degrade over time, becoming brittle and breaking apart
Using plastic bags as insulation in walls is not recommended. Plastic bags are designed to break down over time and become brittle and fall apart. This means that they would not be a permanent solution for insulation. Additionally, plastic bags are not breathable, which could lead to mold issues. The breathability of a material is its permeability, or ability to allow vapour to travel through, otherwise known as the water vapour transmission rate. Plastic bags act as a barrier and trap moisture. As a wall assembly heats up during the day and cools off at night, moisture present in the wall cavity will condense and accumulate within the plastic folds. This liquid water will stay trapped for longer than water vapour, leading to mold issues.
Plastic bags are also flammable, and insulation should not be easily combustible or spread fire easily. Furthermore, plastic bags would not provide uniform air pockets and would not be as effective as traditional insulation materials.
There are other ways to reuse plastic bags, such as donating them to be turned into composite deck boards, benches, or other products. However, the best solution to plastic bag waste is to stop using disposable plastic bags altogether and opt for reusable bags instead.
While plastic bags should not be used for insulation due to their degradation over time, there are other emerging technologies for insulation that use recycled plastics. However, it is unclear how these products avoid issues with mold. Overall, plastic bags are not a suitable material for insulation due to their degradation, flammability, and lack of breathability.

Plastic bags can be recycled into composite deck boards or donated to companies that make benches
Plastic bags cannot be used as insulation for walls due to their non-breathable nature, which could lead to mould issues. They are also flammable, and unable to maintain their structure over time.
Instead of using plastic bags as wall insulation, they can be recycled into composite deck boards. Trex, for example, makes composite decking material and outdoor furniture from reclaimed wood and plastic film. A standard 16-foot Trex deck board uses recycled materials from about 2,250 plastic bags. The company also runs recycling programs that encourage the collection of plastic film with the goal of recycling a minimum of 1,000 pounds of plastic in a 12-month period.
Another option for recycling plastic bags is to donate them to companies that make benches. For instance, the Evergreen Conservancy's "Bags to Benches" project collects plastic and delivers it to Giant Eagle. Once they collect 500 pounds of plastic, they order a bench made from recycled materials. The KFMB "Bags to Benches" program is another initiative that recycles plastic film into benches in partnership with Trex.

Plastic bags can be used to cover fiberglass insulation to fully seal it off from the living space
Plastic bags can be used to cover fibreglass insulation to fully seal it off from the living space. However, it is important to note that this method may not be effective in providing adequate insulation. Plastic bags are designed to break down over time, and they can become brittle and fall apart. Additionally, plastic bags are not breathable, which can lead to mould issues due to trapped moisture.
To address the concerns with using plastic bags as insulation, some suggestions have been made to modify the approach. One idea is to use cloth bags instead of plastic bags to avoid potential moisture issues. Another suggestion is to layer the plastic bags with other materials, such as adhesive tape or local melting, to create a more effective barrier. However, this method may not be practical for commercial builders due to the time and effort required.
It's important to consider the potential drawbacks and limitations of using plastic bags for insulation. Plastic bags may not meet the essential criteria for effective insulation. Insulation should ideally stay in place without settling, be flame-resistant, allow moisture escape to prevent mould, and maintain its structure over time. Plastic bags might not satisfy these requirements without substantial modifications to their design.
While plastic bags may not be the ideal solution for insulation, there are alternative eco-friendly options available, such as mycelium insulation. Mycelium insulation uses spent mushroom substrate to create biodegradable, breathable, and fire-resistant insulation that can be made at home. This emerging technology addresses the limitations of plastic bags while still promoting environmental sustainability.
In summary, while plastic bags can be used to cover fibreglass insulation, it may not be the most effective or safe option. It is important to carefully consider the potential drawbacks and explore alternative solutions, such as mycelium insulation, to ensure adequate insulation and maintain a healthy living environment.

Plastic bags can be used as a vapour barrier to prevent interior moisture from getting trapped in insulated walls
Plastic bags cannot be used as effective insulation for walls due to their lack of breathability. The impermeability of plastic bags means that they act as vapour barriers, trapping moisture inside walls and causing mould and condensation issues.
However, plastic bags can be used as a vapour barrier to prevent interior moisture from getting trapped in insulated walls. This is a standard practice in cold climates, such as Canada, where a vapour barrier is installed on the warm side of a wall. This technique helps to prevent condensation and mould problems by keeping moisture out of the wall cavity.
One way to use plastic bags as a vapour barrier is to staple them to the wall studs before installing the insulation. The plastic bags can be taped together at the seams and sealed with an acoustic sealant to ensure a continuous vapour barrier. It is important to use a special tape designed for this purpose to ensure an effective seal.
Another method is to use a plastic 'sock' or sleeve that is specifically designed to be placed around insulation batts. These plastic sleeves are perforated to allow for breathability while still providing a vapour barrier. This method ensures that the insulation is not compromised by the plastic, as bagging loose insulation can reduce its effectiveness by creating gaps and seams that affect heat transfer.
While plastic bags can be used as a vapour barrier in certain situations, it is important to consider the potential drawbacks. Plastic bags are not fire-resistant, and they can break down and off-gas over time, releasing potentially harmful chemicals. Additionally, the time and effort required to install plastic bags as a vapour barrier may not be feasible for some builders or projects.
