Sandwich board is the two sides are metal, the middle of the building materials is the problem of foam added: What is the use of more adhesive

Buy the quality of a little bit of what the material is no problem, although the price is more expensive, but the first safety is important
Wood insulation effect can be, the smaller the density the better insulation, asbestos or glass wool will be better, but the price of your Kazakhstan
