Warmshell doesn't just save carbon in use...
It is also fundamentally more sustainable and safer to make and dispose of. By building a system designed to manage moisture using the inherent advantages of natural materials, we avoid the need for toxic chemicals or additives which have high embodied energy.
We're currently working on our full EPD for the system to demonstrate this more methodically. In the meantime you can see on the link below how Woodfibre locks carbon up when being made, unlike most insulations which are resource and energy intensive to make
Each pallet of Warmshell Woodfibre locks up over 400kg of CO2 e.q. during its life, even when taking into account the energy used to make it and ignoring the energy it will save you in use. Compare that to aluminium foil-faced insulation, where the same volume can release around 1300kg during manufacture!
