Recycled PET plastic is used for building insulation
Polyethylene terephthalate (PET) is a plastic commonly used in the production of bottles, packaging, and fibers for clothing and carpeting. PET is widely recycled, with one of the primary uses of recycled PET being the creation of new packaging. However, there is growing interest in utilizing recycled PET for building insulation.
Recycled PET-based panels for building insulation have been developed to offer a more environmentally friendly alternative to traditional insulation materials. These panels are made from 100% polyester, with 80% recycled and 20% synthetic virgin material. The panels are nonwoven, making them easy to handle and suitable for external walls and coverings.
One example of recycled PET insulation is SupaSoft, which is manufactured in the UK from recycled plastic bottles. It is safe to handle and install, containing no harmful chemicals. SupaSoft helps to reduce carbon emissions, divert waste from landfills, and lower domestic energy use. The insulation is produced using thermal bonding technology, ensuring the recycled PET fibers are strongly bonded together and will not slump over time.
In addition to recycled PET panels and rolls, cellulose is another recycled material that can be used for building insulation. Old newspapers, for example, can be recycled into an environmentally friendly insulating material. Boric acid or ammonium phosphate is added to cellulose to address its flammability, and an additive is included to protect against mold and pests. This type of insulation is introduced into hollow cavities in the form of flakes for roof insulation or in wooden wall structures.
The use of recycled PET and other materials for building insulation offers several benefits. Firstly, it helps to reduce the environmental impact of construction by utilizing waste materials and reducing the need for virgin resources. Additionally, recycled insulation materials often have lower energy consumption during production, further reducing their carbon footprint. Recycled insulation options are also often cheaper than traditional alternatives, making them a more cost-effective choice.

It is made from recycled plastic bottles
PET insulation made with plastic fibers is recyclable and is often made from recycled plastic bottles. In fact, the most common use for recycled PET plastic is in retail packaging. PET plastic can be recycled back into the same format, meaning old PET plastic bottles can be turned into new ones. This process can be repeated, reducing pollution and decreasing an organization's carbon footprint.
The process of recycling PET plastic into packaging or insulation involves breaking down the plastic into its base polymers. These polymers are then used to produce polyester fibers, which are used for insulation. This method of recycling PET plastic into fibers is the most common way of using PET-flakes. The resulting product is a nonwoven panel made of 100% polyester, with 80% recycled and 20% synthetic virgin material.
The use of recycled PET plastic for insulation has several benefits. Firstly, it helps to divert waste plastic from landfills and incineration, protecting the environment. For example, it takes an average of 12,000 waste plastic bottles to produce enough insulation for a typical loft, preventing these bottles from ending up in landfills or being incinerated. Secondly, recycled PET insulation is safe to install and does not emit harmful chemicals.
Additionally, recycled PET insulation can help reduce energy consumption and lower carbon emissions associated with transportation. The insulation is manufactured in the UK, reducing the carbon footprint associated with long-distance transport. It also comes in a compressed roll, further reducing packaging waste and carbon miles. Recycled PET insulation is a more environmentally friendly alternative to conventional insulation materials, which often use non-renewable resources and have a negative impact on the environment during production and disposal.

It helps reduce waste and carbon emissions
Polyethylene terephthalate (PET) is a type of plastic commonly used for packaging, bottles, and fibres in clothing. It is widely recycled, with the prime uses for recycled PET being polyester fibre, strapping, and non-food containers.
Using recycled PET for insulation helps reduce waste and carbon emissions in several ways. Firstly, it diverts waste plastic from landfills or incineration, protecting the environment. For example, it takes an average of 12,000 waste plastic bottles to produce enough SupaSoft insulation to cover a typical loft, preventing these bottles from being buried in landfills or burned.
Secondly, recycled PET insulation helps reduce domestic energy use. For instance, SupaSoft Insulation is made from polyester fibres that provide long-lasting thermal insulation in buildings. This reduces the need for energy-intensive heating or cooling, thereby lowering carbon emissions and energy costs.
Recycled PET insulation also reduces carbon emissions during the manufacturing process. Manufacturing carpeting or insulation from recycled plastics produces fewer emissions than using virgin plastics. Additionally, recycled PET insulation reduces packaging waste and carbon miles due to its compressed packaging, which is easier to transport.
Furthermore, the use of recycled PET in packaging helps organizations decrease their carbon footprint. Recycled PET containers retain the same structural integrity and transparency as non-recycled PET containers, while also being recyclable themselves. This reduces pollution and encourages a circular economy.
Overall, the use of recycled PET insulation helps reduce waste and carbon emissions by repurposing waste plastic, improving energy efficiency in buildings, lowering emissions during production, minimizing packaging waste, and promoting the recyclability of packaging materials.
