The conductivity factor is a very important index to evaluate the heat-insulation and cold-insulation influence of the warmth-preservation materials. The reduce the conductivity issue is, the greater the warmth-insulation efficiency are going to be. The conductivity aspect of the product is 0.034w/m�?k at a median temperature 0 �?.
