ThermaCork continues to be a very popular product with Small Planet Supply customers. Between the natural beauty and impressive insulative value, there is certainly a lot to love about this 100% natural product. One great thing not everyone is aware of though is how ThermaCork has a less than zero carbon footprint. This negative carbon footprint is an important part of the fight against climate change and ThermaCork is a great way to help bring down the overall carbon footprint of a building.
