Recycled plastic insulation is made from recycled fibres from plastic bottles
Plastic insulation is an option for homeowners looking to improve their home's energy efficiency. It is made from recycled fibres from plastic bottles, which are ground into flakes, heated, and then extruded into polyester fibre. This process creates a durable insulation material that can be used in lofts to prevent heat loss.
One of the benefits of recycled plastic insulation is its ability to reduce energy consumption. By installing insulation in the loft, homeowners can prevent heat loss during winter and keep their homes cooler in the summer. This reduces the need for artificial heating or cooling, leading to lower energy costs and a reduced carbon footprint.
However, there are some concerns about the potential risks of using recycled plastic for insulation. One issue is the presence of chemicals such as Bisphenol-A (BPA) and phthalates in plastic. BPA is known to disrupt hormones, while phthalates have been linked to immune system impairment, especially in men and boys. Despite these chemicals being banned by the European Union in 2005, they may still be present in older plastic products.
Another consideration is the flammability of recycled plastic insulation. While some sources suggest that it burns slowly and primarily melts when exposed to fire, it is important to note that it will still burn. Eco-wool, a type of recycled plastic insulation, is fully certified to meet UK and European fire safety requirements. It does not propagate flames and extinguishes when the source of the fire is removed.
Overall, while recycled plastic insulation offers benefits in terms of energy efficiency and reducing waste, it is important for homeowners to carefully consider the potential risks and ensure that any insulation they choose meets the necessary safety standards.

Recycled plastic insulation is an environmentally-friendly product
Recycling improves our carbon footprint and contributes to a healthier and better environment. However, not all plastic objects can be recycled. Recycled plastic insulation is made from recycled fibre from plastic bottles. For loft insulation, plastic bottles are ground into flakes, heated, and then extruded into polyester fibre.
Another benefit of recycled plastic insulation is its durability. SupaSoft, for example, is made from recycled PET and is extremely durable. Because the binder is made from PET, it does not degrade or slump over time. This means that SupaSoft will last the life of the building so once installed, there is no need to replace it.
However, there are some risks associated with recycled plastic insulation. For example, chemicals like Bisphenol-A and phthalates are found in plastic. Bisphenol-A is often added to plastics to make them more durable, but it is known to disrupt hormones. Phthalates, which were banned by the European Union in 2005, are considered harmful to men and boys and are linked to immune system impairment.
There are also concerns about the flammability of recycled plastic insulation. While some sources suggest that it burns slowly and mostly just melts, it is important to note that it would have to pass British Standards for flammability to be sold. Eco-wool, for example, is fully certified to meet UK and European fire resistance requirements.

Chemicals like Bisphenol-A and phthalates are found in plastic
Recycled plastic insulation is made from recycled fibre from plastic bottles. Plastic bottles are ground into flakes, heated, and then extruded into polyester fibre. However, chemicals like Bisphenol-A (BPA) and phthalates are found in plastic, and these can have harmful effects on human health.
Bisphenol-A is often added to plastics to make them more durable. It is used in hard, clear plastic, like baby bottles, sippy cups, and teethers. BPA can also be found in food storage containers and the lining of many food and beverage cans. It is known to disrupt hormones, and exposure to high levels of BPA has been associated with adverse effects on reproduction in animal studies. There is also some evidence of a possible effect on reproductive hormones in men.
Phthalates are used to make plastic soft and flexible. They are often found in car interiors, shower curtains, deodorant, cosmetics, and medical devices. Phthalates can also be found in children's products, such as toys, rattles, teethers, and baby shampoo. They are considered harmful to men and boys and have been linked to immune system impairment.
The harmful effects of these chemicals may be cumulative, meaning that steady exposure to even small amounts over time could increase health risks. This makes it difficult to trace any particular bad health outcome, such as a heart attack or breast cancer, to the chemicals. However, growing research shows that Bisphenol-A and phthalates are endocrine disruptors, which means they can interfere with the production and regulation of estrogen and other hormones. Even minor disruptions in hormone levels can contribute to an increased risk of several health problems, including diabetes, obesity, cardiovascular disease, certain cancers, birth defects, premature birth, neurodevelopmental disorders, and infertility.
To minimize exposure to these chemicals, it is important to avoid using plastic containers in microwaves, as BPA can leach from plastic containers into food and beverages, especially when heated or used for long periods. It is also recommended to avoid vinyl toys, perfumed shampoo, and lotion, opting for fragrance-free products whenever possible.

Eco-wool is a fully certified fire-resistant insulation material
Eco-wool is a great alternative to recycled plastic insulation, which has been found to contain harmful chemicals such as Bisphenol-A and phthalates. These chemicals are known to disrupt hormones and are considered harmful to men and boys, respectively. While recycled plastic insulation is beneficial for the environment, it is not as cost-effective in the long term as other insulation materials.
In contrast, Eco-wool is not only environmentally friendly but also provides better benefits. It does not propagate flames and will self-extinguish when the source of the flame is removed. This is because wool has a high nitrogen and water content, requiring higher levels of oxygen to burn than is usually present in the environment. Additionally, wool's cross-linked cell membrane structure swells when heated to the point of combustion, forming an insulating layer that prevents the flame from spreading.
Eco-wool is also a good alternative to other natural insulation materials, such as sheep's wool, which can be difficult to source and expensive. It is also a safer option for those who are allergic to other insulation materials, such as glass fibre. Overall, Eco-wool is a certified fire-resistant insulation material that is environmentally friendly, effective, and safe for those with allergies.

Recycled plastic insulation is more expensive than glass fibre insulation
While recycled plastic insulation is more expensive than glass fibre insulation, it is still a popular option for those looking to reduce their environmental impact and non-renewable energy use. By reducing waste and energy consumption, recycled plastic insulation helps to mitigate the effects of climate change while keeping your home warm and comfortable.
There are several reasons why recycled plastic insulation is more costly than glass fibre insulation. Firstly, the production process for recycled plastic insulation is more complex and involves higher costs. Plastic bottles are ground into flakes, heated, and then extruded into polyester fibre, requiring specialised equipment and labour. On the other hand, glass fibre insulation is made from inexpensive materials such as glass fibres and sand, which are readily available and easy to process.
Another factor contributing to the higher price of recycled plastic insulation is the demand for eco-friendly and sustainable products. As consumers become more environmentally conscious, they are often willing to pay a premium for products that are kind to the planet. Recycled plastic insulation appeals to those who value sustainability and are looking for ways to reduce their carbon footprint.
It's worth noting that while the initial investment in recycled plastic insulation may be higher, it can be a cost-effective option in the long run. Recycled plastic insulation is known for its durability and long-lasting nature. It is resistant to moisture, mould, mildew, and fungi growth due to its water-repellent properties. This extended lifespan of recycled plastic insulation can offset the higher upfront cost over time.
Additionally, recycled plastic insulation offers significant energy savings and decreased heating expenses. The plastic fibres effectively trap air, creating a barrier that blocks heat transfer. This results in reduced heat loss, improved energy efficiency, and lower heating costs for homeowners. Therefore, while recycled plastic insulation may have a higher upfront cost, it can lead to long-term savings on energy bills.
