These are all pretty effective, and all involve the use of recycled materials. Polyester insulation is made from recycled plastic (PET) bottles, while cellulose insulation is largely made of recycled paper. Fibreglass also includes recycled glass; according to the company Aerolite, which installs this kind of insulation, up to 80% of their product is made from recycled materials.

There is a small risk that fibreglass fibres can cause skin, eye and respiratory irritation when insulation is being installed or removed, but this can be easily avoided if correct health and safety procedures are followed. Fibreglass has not been linked to serious long-term health problems.Companies that install cellulose insulation include Thermguard and Eco-insulation. Companies that install polyester insulation include Home Comfort and Insuthem.Image: Shutterstock Olivia Rose-Innes, EnviroHealth Editor More in Lifestyle New natural wonder: Giant living SA flag More: EnviroHealthGreen tips SPONSORED: So many prizes!
