1. Fiberglass insulation is well-known in the market. The pros are the heat will be kept inside the insulation, light-weighted, nonflammable, low smoke, and safe to health, but can be itchy after contacting. It is available in sheet, roll, and wrapped
2. Rockwool/Stone wool insulation is the thermal insulation made from stone wool which its fiber size is 4-5 microns. The pros are high density, good compressive strength, nonflammable, low smoke, safe to health, but can be itchy after contacting, not absorb water so it will not be getting mold. It is available in sheet and roll. If it is the Asbestos, the natural inorganic mineral with the fiber size smaller than 3 microns not safe for health, it may cause cancer.
3. EPS Foam insulation (Expanded Polystyrene Foam) or also known as the white foam can prevent from heat and cool, and excellent compressive strength. The normal grade of white foam will flammable and create smoke, but the nonflammable grade white foam from KS Group will be nonflammable and safe to health. It is available in separated and prefabricated sheet which is the roof insulated panel (sandwich roof) from the factory, light-weighted, easy to move so it is easy and fast for installation, and shorten the construction procedure.
4. PE Foam insulation (Polyethylene Foam) is soft, tough, and thick, covering with thin foil which flammable, low smoke, and less for heat and noise reduction because it is thinner than other insulation.
5. PU Foam insulation (Polyurethane Foam) or also known as yellow foam will be nonflammable but the fire will drop around, high smoke, not safe to health, so it must be used with awareness. In the case of customer’s need, the manufacturer can add the flam-retardant. It is available in sheet, spraying, and also the insulated sheet from the factory.

Form the above article, there are many types of “Thermal Insulation”, so choose the suitable one that match the usage for the most benefit of the house.
