What are the best types of insulation materials? How to choose thermal insulation materials?

Thermal insulation material is the most common decoration material at present. This material is generally used for exterior walls, which can keep out the cold, so everyone especially likes this material. So, do you know which types of insulation materials are the best? Let's take a look at the best insulation materials and how to buy them with you.

What are the best insulation materials?

1. Rock wool board is based on basalt material. After high temperature melting treatment, it becomes artificial inorganic fiber. It has the characteristics of light weight, low thermal conductivity, heat absorption and difficult ignition. It is a new type of thermal insulation material and flame retardant, which is widely used in buildings at present.

2. Phenolic foam is a kind of polymer organic aluminum foil foam product, which is mainly formed by foaming thermosetting phenolic resin. It has the advantages of light weight, fire prevention, open flame, non-combustion, smokeless, non-toxic and non-dripping, and will not shrink and embrittle in high and low temperature environments. It is a high-quality material refrigeration project of HVAC.

3. Mineral wool is made of mineral wool, rock, slag and fifteen-grade mineral cellulose. It is mainly used for various pipeline insulation, especially in industries working at high temperature. Pipes.

4, polystyrene foam board This is the most common one, also known as "foam board, EPS board", which is a white object heated by volatile liquid, mainly used for thermal insulation of building walls and roofs.

5. Polyurethane foam is a combination of polyurethane prepolymer and other foaming agents. When the material is ejected from the aerosol can, the foamed polyurethane material will expand rapidly and expand together with the moisture in the air. A curing reaction takes place to form foam.

6. Glass fiber cotton is also one of them. But it is made of glass balls or waste glass and then melted at high temperature. Its diameter is very small, equivalent to 1/20 of hair, and its performance is also very good. Very good.

How to choose thermal insulation materials

1, general insulation materials are divided into four grades, namely flammable, combustible, flame retardant and incombustible. When we make the insulation layer of the house, we should choose flame retardant materials. When buying, first check whether there is a qualified mark on the packaging of insulating materials. , firepower level and firepower level are several levels. 2. Of course, the biggest function of thermal insulation materials is to keep warm, so its thermal insulation performance is the key to purchasing products. When buying, you must know the insulation of insulating materials, and you can look at the thermal conductivity of materials.

3. When purchasing external wall thermal insulation materials, its waterproof performance, freeze-thaw resistance, weather resistance, impact resistance and wind pressure resistance must be good, because external wall thermal insulation needs to face natural wind and sunshine directly, so these must be achieved.

Standard.

4. External wall insulation materials require no high insulation layer, but good quality insulation materials, especially refractory materials, must also be selected.

5. Theoretical analysis shows that no thermal insulation material has all the above characteristics, but we are good at optimizing the combination and can process several different types of materials together to meet the above requirements. Therefore, the current interior wall insulation board is a composite structure of "skin plus filler".

Thermal insulation material is a kind that everyone likes. When choosing it, everyone needs to have a certain understanding of its type. The above are the best types of insulation materials and how to choose them. Through the introduction, I believe everyone has a certain understanding of thermal insulation materials.
