Yes I have a few materials that would be interesting to test and more importantly are recovered from waste materials which makes them interesting for funding purposes.
I've got a material for you. It's been used in the Solar Impulse 2. They say is very thin and light and also provides high levels of insulation. It is used on refrigerators.
I find it important because you can use it in restoration of old buildings, where you can save area as it is so thin.
Aparently they are now going to try it at a house model (see link attached).
