Home insulation is an essential part of the sustainability plan; but it kind of defeats the purpose if the production of the insulating materials has a massive carbon footprint themselves. Going green in this way is easier than you might think, and often more effective and cheaper than most people would think.

So long as you ensure the environment doesn’t prohibit its use (exposure to moisture etc), then wool is a great option – whether you choose a branded, treated product or use it in its raw form. Flax and hemp, wood fibre and expanded clay aggregate are other materials recommended to home owners. There are dozens of other, more obscure, materials which can be used to the same effect.

If you want to take it a step further, you can learn about what materials are effective insulators and then use as much self-sourced materials which would otherwise be considered waste.
