The comparison between cement foam board and cement polystyrene board is also energy saving

Cement foam board is environmentally friendly, energy-saving, pollution-free, and has a strong service life.

The thermal insulation performance of cement polystyrene board is better than that of cement foam board. Because the heat conduction of EPS is lower than that of air (air bubbles in cement foam boards). Therefore, cement polystyrene board is more energy-efficient than cement foam board.

What is cement polystyrene board? Is it a thin plastering system? EPS board and thermal insulation and durability are of course better than foam board, foam board is more garbage.

The difference between composite cement foam board and siliceous modified polystyrene board: siliceous board, also known as silicon-sen-modified polystyrene board or siliceous thermosetting polystyrene board, is a new type of thermal insulation material that is improved on the basis of traditional polystyrene board to achieve the most flame retardant effect. It not only continues the advantages of small thermal conductivity and good thermal insulation effect of traditional polystyrene board, but also makes up for the shortcomings of poor flame retardant effect of traditional foam board, and overcomes the problem of heavy quality and high quality of similar flame retardant materials on the market, which is an ideal thermal insulation material with a wide range of market demand.

Cement foam board is the upgrade of general organic insulation materials, it can be said that it is the perfect combination of insulation materials and cement building materials, its service life is much longer than the general organic insulation materials, and the function is much more than the general cement building materials, so it is a building material that many people like to use. So, is cement foam board good? Now I will introduce to you the performance of cement foam board and the advantages and disadvantages of cement foam board to help you understand cement foam board.

Advantages and disadvantages of cement foam board

1. Product advantages:

1. High fire resistance.

It is an inorganic material, which is a class A fireproof material, so as to have good fire resistance, and the fire resistance reaches more than 1000, which fully meets the fire resistance requirements of the exterior wall insulation board.

2. High thermal insulation.

Closed cell ratio of 95%, high closed cell rate makes the heat transfer caused by air flow low, which is a prerequisite for high thermal insulation. Therefore, the thermal conductivity of the external wall insulation board produced has reached slightly lower than that of the polystyrene board, but the use effect in the actual project is basically the same, which can meet the needs of building thermal insulation. Wu Na.

3. The strength is relatively good, and it is not easy to break.

The compressive and flexural strength of the plates produced by the company is high, which has achieved the relative unity of low density and high strength, and is not easy to break in use and transportation, and conforms to the integrity of fire resistance.

4. Light weight and high bonding strength.

Light weight is another advantage of our products. The density is 150-300kg m3, which can meet the requirements of external wall insulation board and reduce costs. The compatibility of the material is good, and the adhesion to the wall is strong.

5. Non-toxic, harmless, environmentally friendly and energy-saving.

It is based on cement and fly ash as the main raw materials, which will not burn at high temperature and no toxic gas is released.

6. Long life.

The current design life of buildings in China is generally 50-100 years. However, the design life of organic insulation materials is mostly only 20-25 years. In other words, the insulation cannot keep pace with the life of the building.

This means that the aging resistance of organic insulation materials makes a building have to undergo at least 2-4 thermal insulation construction during its service. This repeated construction operation of the building caused direct damage to the building itself. The service life of the building is shortened, and at the same time, many thermal insulation constructions also bring serious inconvenience to people's production and life.

The life span is more than 50 years, and it can have the same life as the building.

Second, its disadvantages are:

Low strength (brittle) and high water absorption, which cannot be compared with wall insulation materials such as foam glass, foam ceramics, phenolic foam boards, polystyrene particles, polystyrene boards, and extruded plastic boards.

Above, to answer the question of whether the cement foam board is good, mainly from the advantages and disadvantages of the cement foam board to introduce, from the product performance, service life, environmental performance and thermal insulation these characteristics, cement foam board is indeed worthy of many construction industry to use, but the material has excellent orange reed points also have shortcomings, low water absorption rate determines that some rain, high temperature and humidity areas can not be used, so consumers should consider the climate of the region when buying.

Cement foam board is better.

Polystyrene foam board and cement foam board are thermal insulation materials and have a certain flame retardant function, which is better, depends on the difference between the two: cement foam board insulation effect is better. The thermal insulation layer is to prevent the heat from being transferred downwards and to make the heat transfer unilaterally upward, which can save energy.

Therefore, the insulation material must have a very good thermal insulation effect, must have a certain strength to withstand the pressure above, and fix the water pipe. The quality of the insulation layer directly affects the quality of the project.

Polystyrene foam board, also known as foam board, EPS board is made of expandable polystyrene beads containing volatile liquid foaming agent, heated and formed in the mold after heating pre-hair, which has the structural characteristics of fine closed cells, mainly used for building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicles, ships thermal insulation, floor heating, decoration and carving and other uses are very wide.

Protect the main structure of the building and extend the life of the building. Because the external insulation layer is placed on the outside of the structure, the stress caused by the structural deformation caused by temperature changes is reduced, and the erosion of harmful substances and ultraviolet rays in the air is reduced, and the environmental protection index is better.

Low thermal conductivity.

The moisture temperature of the wall is improved.

Class B1 fireproof.

Light weight. Cement foam board is a thermal insulation board made of broken particles of waste polystyrene foam as aggregate, cemented with ordinary cement, and stirred with foam stabilizer and foaming agent.

Cement foam board has the following characteristics:

Good thermal insulation effect, no water absorption, freeze-thaw resistance, low thermal conductivity. The fire rating is high, reaching A2 fire resistance.

Convenient construction. Beautiful and long-lasting.

High adhesion to the base layer.

Low cost. Polystyrene foam board is environmentally friendly, has a long service life, can improve the damp wall, but is easy to deform, and the thermal insulation effect is not very good. The thermal conductivity of cement foam board is to meet the requirements of floor heating insulation materials, its thermal conductivity is small, the compressive strength is high, the chemical properties are stable, environmental protection, not easy to deform, and the leveling layer and the insulation layer are integrated, the construction is fast, and the cost is low. In contrast, cement foam board has more advantages.

First of all, from the developer's point of view, cheap is the last word, foamed cement is cheaper, and the construction is almost the same; From the national requirements, polystyrene foam board is not fireproof, thermal insulation performance should be good, foamed cement, fire insulation can be done, thermal insulation performance is certainly not as good as organic polystyrene, comprehensive consideration of foamed cement or market, what problems we can communicate with each other.

Cement foam board is actually a kind of board that combines insulation materials with cement building materials, its service life is longer than that of ordinary boards, and as a building material, its function is much more than cement, so how about cement foam board? For the owners who have just renovated, there is no deep understanding, and today I will tell you about the advantages and disadvantages of cement foam board.

First, the advantages of cement foam board.

1. Fireproof and high temperature resistant.

Cement foam board is an inorganic material, so it is a relatively high fireproof material, so its fire resistance point can reach more than 1,000 degrees Celsius, so it will not be afraid of high temperatures.

2. Thermal insulation.

Because its surface is a high closed cell rate, the heat conduction of the air flow on its surface is relatively low, which is also a prerequisite for our high thermal insulation, so its thermal conductivity is very low, which can keep our indoor temperature warm.

3. Good stability and long life.

The cement foam board is compressive and bending-resistant, so it will not be broken during transportation, so its stability is also very good; And its service life can reach fifty to one hundred years, while ordinary insulation materials are only twenty or thirty years.

4. Light weight and environmental protection.

The material of cement foam board is relatively light, but it still has various properties; Its main raw materials are cement and fly ash, which will not burn and release toxic gases in a high-temperature environment, and are very safe and environmentally friendly materials.

Second, the disadvantages of cement foam board.

1. It is brittle and not waterproof.

The disadvantage of cement foam board is that it has an extremely high water absorption rate, so it cannot be used in a humid environment or rainy days, and cannot be compared with other wall insulation materials.
