I’m from germany – the homeland of orders and regulation. Amongst many others, there is an overabundance of strict and in-depth building laws to follow meticulously. So, as a decent citizen I have diligently insulated the chicken den to keep up to our beloved green party’s visionary energy saving laws. </irony off>
Well, ok, also to keep it frost free and cozy for the girls over the winter 😁 It kept an inside temperature of 6°C when it was -4°C at night, just from body heat. I’m pleased with this result.
I used 30 mm Jackodur ™ for insulating, which is waterproof, rot resistant and non toxic. It is a popular material for the thermal insulation of basements, so it’s available in every hardware store and it’s fairly affordable.
