This research is to study the production of insulation from natural fibres and natural rubber latex. From natural plant cellulose fibers as insulation The use of natural materials because of the cellulose fibre is a key element which does not contain spaces, and the filament inside the small stores have similar conditions as the insulation, because the heat that is transmitted through the air and Qual. The thermal resistance of the heat extraction method, as a result no convection occurs. Heat radiation. The study found that thermal conductivity is variable according to the density of the material, the better the insulation thickness is the better the insulation and high thermal conductivity and (K-value) the value, the less it will heat as well. It is therefore with good thermal insulation.
