7 CHEAP AND MOST COMMON THERMAL INSULATION MATERIALS
Minh Quan Insulation Materials Company would like to introduce to our readers an article about the 7 best and most used types of THERMAL INSULATION MATERIALS currently on the insulation market.
Currently on the market there are many cheap and popular insulation materials. Many of these products have been around for a long time. Each of these insulation materials has its own ups and downs. Therefore, when deciding which insulation material to use, you should be sure which material will work best in your situation. We've looked at differences like R-value, price, environmental impact, flammability, soundproofing, and more below.

Below are the 7 most popular types of insulation materials today.

1. Glass fiber (glasswool):

Fiberglass is the most popular insulation material used in modern times. Because it consists of many very thin glass fibers arranged into a porous structure similar to wool and is bonded together flexibly, creating a product with heat-insulating, sound-insulating, and fire-resistant capabilities good, durable to the environment, not corroded by chemicals, fiberglass can minimize heat transfer. The main disadvantage of fiberglass is that it causes skin irritation to NEW people when handling it. However, when proper safety equipment is used, fiberglass installations can be performed without incident.

2. Rockwool fiber (rock wool):

Mineral wool actually refers to several different types of insulation. First, it may refer to glass wool which is fiberglass produced from recycled glass. Second, it may refer to rock wool, a type of insulation made from basalt. Finally, it may refer to slag wool produced from slag from steel mills. The majority of mineral wool in Vietnam is actually made from rock wool.
3. Cellulose:
Cellulose insulation is perhaps one of the most environmentally friendly forms of insulation. Cellulose is made from recycled cardboard, paper and other similar materials and comes in loose form. Cellulose has an R value from R-3.1 to R-3.7. Some recent research on cellulose has shown that it can be an excellent product to use in minimizing fire damage. Due to the density of the material, cellulose does not contain oxygen within it. There is no oxygen inside the material, which helps minimize the damage that a fire can cause.

4. Polyurethane Foam:

Although not the most abundant insulator, polyurethane foam is an excellent form of insulation. Today, polyurethane foam uses chlorofluorocarbon (CFC)-free gas for use as a blowing agent. This helps reduce the amount of damage to the ozone layer. They are relatively light, weighing about 2 pounds/cubic foot (2 lb/ft^3). They have an R-value of approximately R-6.3 per inch of thickness. There are also low-density foams that can be sprayed into uninsulated areas. These types of polyurethane insulation tend to have an R-3.6 rating per inch of thickness. Another advantage of this type of insulation is that it is fire resistant.

5. Polystyrene:

Polystyrene is a waterproof thermoplastic foam that is an excellent sound and heat insulating material. It comes in two types, expanded (EPS) and extruded (XPS) also known as foam. The two types differ in performance ratings and costs. The more expensive XEPS has an R-value of R-5.5 while EPS is R-4. Polystyrene insulation has a unique smooth surface that no other type of insulation has.

6. Asbestos (asbestos):

Asbestos is a double silicate of Calcium (Ca) and Magnesium (Mg), containing naturally occurring SiO2. Asbestos includes 02 groups: (a) Serpentine group: Chrysotile (Chrysotile) has a twisted form and is also the only type of Asbestos fiber still commercially consumed on the market today.

7. ceramic (ceramic fiber):

Ceramic fiber fabric is a textile fabric manufactured from high purity Alumino-silicate based ceramic fiber, reinforced with fiberglass and optional alloy steel wire. Ceramic fabric is white and odorless, suitable for high temperature applications up to 2,300°F
