I have been trying to find answers to this on the internet and sites only cover the basics regarding reflecting heat.
I am curious if mylar (space) blankets will still serve their purpose in a shelter if they are covered by pine or other insulating materials.
Since these blankets are cheap and not the best option for long term survival, they obviously wouldn't be ideal for a long term shelter.
IF this were necessary, i.e. bugging out turned into a longer term scenario and the mylar blanket was in your pack, would you place it on the inside of your shelter or the outer layer?
I know they reflect heat and can help trap heat, but is this reduced if you were to cover the blankets with an outer layer, whether it be a dense layer of pine or some other form of cover.
