Now, more than ever, making eco-friendly choices are vital for creating a sustainable future. And sometimes, when the stars align, the eco-friendly choice will not only be good for the planet, but it will be good for you and your wallet.
When it comes to home roof insulation. There are a lot of bad choices you can make. Some older home insulation products can be both flammable and toxic, while others are extremely harmful to the environment. But this doesn’t mean you’re stuck only with bad choices.
There are plenty of wall and ceiling insulation products that are not only good for the environment, but are also safe, affordable and provide premium insulating properties.
So, let’s have a look at 5 eco-friendly insulation materials.
1. Sheep’s wool
Wool may be the most natural and sustainable of all insulation materials. A single sheep can produce up to 13 kilograms of wool in a year, depending on the breed. That means that wool is a plentiful and renewable resource.
Wool fibres create a thermal barrier by forming millions of tiny air pockets. That means it traps air, creating a powerful thermal barrier.
Sheep’s wool is also fire retardant and helps to regulate humidity in your home.
2. Cotton or denim
Cotton – and denim, which is made from cotton – is a natural and renewable resource. Denim insulation is made from shredding and recycling fabric off cuts that would otherwise go into landfill.
While cotton isn’t naturally fire retardant, cotton insulation is treated with a borate solution to ensure it’s 100% fire safe. Cotton is also a natural insect repellent.
Cotton and denim insulation are more expensive than traditional fibreglass insulation. However, an eco-friendly choice is money well spent.
ThermaCork is a revolutionary eco-friendly insulation material. It actually has a negative carbon footprint and is natural, renewable and biodegradable. Even better, it also has no toxins and has sound-cancelling qualities.
ThermaCork is made from the outer bark of cork oak trees. No trees are cut down to make this insulation and any waste is used to fuel the manufacturing process. Up to 93% of the energy required to make ThermaCork comes from its waste products.
Aerogel is one of the most effective insulation materials on the market. It’s made by placing silica under high temperature and pressure, then removing the liquid. The end result is a material that is more than 90% air. This molecular structure creates a strong thermal barrier.
Aerogel has an R-value of 10.3 per inch of thickness. The R-value measures a barrier’s resistance to heat flow. The greater the R-value, the greater the resistance to heat transfer, and the greater the insulating effect and subsequent energy savings.
To put that into perspective, wool has an R-value of 3.5 to 3.8 per inch of thickness, and fibreglass and cotton have an R-value of 3.2 per inch of thickness.
Aerogel insulation can be one of the more expensive insulation options. However, it’s incredible R-value makes it a highly effective insulation choice and will help to significantly reduce energy costs.
Made from castor oil, Icynene is another sustainable insulation choice. This oil is made into a spray foam that expands to nearly 100 times its original volume. As it foams, it traps air bubbles, creating a thermal barrier.
Because of its expansion properties, Icynene will tightly seal any gaps so you may need to install a ventilation system alongside the insulation.
These are just five of the eco-friendly insulation options on the market today. Other options include cellulose, polyester and earthwool.
Before deciding on insulation for your home, it’s worth considering the eco-friendly choices. There’s a wide range to choose from, with most performing just as well as the less eco-friendly options. So, make the green choice today.
