wood, cotton, asbostes and perlite

Thank you for your answer. My question wasn't quite good. I know the materials used for insulation and in our university we have done a lot of meaasurements and tests as well. My idea was, that maybe you can guide me to some other research works done with straw (the most common material from nature) or some other material like this for finding the thermal conductivity and thermal transmittance of some enclosures insulated with these materials.

Hi,

I have done some research on the thermal conductivity of straw, saw-dust, shreded paper, hempcrete etc. One of my paper is uploaded on my profile. Hope will serve you. About hemp insulation and other natural insulation, you can search for dr. Eshrar Latif's work. Regards

Hello

Thank You very much. It was useful. Have You got something like this about hemp? May be references? Are you yourself interested in natural insulation materials?

Sirje 

I am very interested to promote those kinds of materials. I believe and promote natural materials for individual dwellings. About hemp, you should look up for dr. Eshrar Latif work. I know that he finished his PhD thesis in hemp insulation. Also dr. Ranyl  Rhydwen have some research on Hemp and binder insulation. You should search for Centre for Alternative Technologies, Wales.

Success on your work!

Dear Sirje,

It is generalized question, you may specify the purpose and  thermal parameters.

as @Peiliang Cong mentioned "wood, cotton, asbostes and perlite"

Regards!
