Advantages and disadvantages of polystyrene foam board

Advantages——

1. Polystyrene foam board has a low density coefficient, good impact resistance and sufficient ability to absorb external impact forces by changing and restoring its shape;

3. Its surface has low water absorption and good anti-penetration performance, which can effectively prevent the wall. moisture, peeling and other wall problems;

4. Not affected by temperature. At high temperatures, polystyrene foam boards will not melt and flow due to too high temperatures, and at low temperatures, they will not cause brittle cracks due to too low temperatures;

5. . , can be recycled and its recycling degree is the highest among plastics;

6. Freon is not used in the process ofe production;

7. is the lowest among plastic products.

Disadvantages -

1. The construction requires hanging nets, the construction process is tedious, and the construction period is long

2. It is flammable and produces toxic products; gas after combustion. Ordinary polystyrene foam insulation boards are easy to burn, and the smoke produced by combustion is toxic. Even after adding flame retardants, the flammability can only reach Class B;

3 . The material has low strength and is easy. to produce Cracks and detachment of the insulating layer are common;

4. Due to their limited strength and low bearing capacity, polystyrene foam insulation boards need to be reinforced when facing bricks;

5. The quality of polystyrene foam insulation board is unstable because the material must beplaced for a period of time before leaving the factory and can be used after a period of maturity. If it is not fully matured, the quality cannot be obtained. be guaranteed, causing the foam board to shrink and crack.

Which extruded boards or foam boards should be used for underfloor heating?

1. Extruded boards, also called XPS boards, are the third generation of rigid foam insulation materials. It offers superior performance that cannot be replaced by EPS cards. Its density is 35Kg/m3 and its thickness is 4.0 cm.

2. Foam board for underfloor heating is also called polystyrene foam board and EPS board. It is mainly used for building wall and roof insulation, composite panel insulation, cold storage, air conditioning, vehicle insulation, ship insulation, etc. .Very poversatile.

3. Nowadays, almost all underfloor heating insulation boards use XPS (extruded polystyrene plastic board). The advantages are low thermal conductivity and high compressive strength. also good and bad XPS cards. The most obvious is the use of raw materials. The more recycled materials used, the worse the quality of the XPS and the lower the cost.

4. To be used as an insulating material, thermal conductivity is a very important criterion. The foam board has an independent bubble structure, low thermal conductivity, generally less than 0.039 W/(m·k), low density and light weight. In addition, the surface of the foam board has low water absorption, good anti-penetration ability and can be recycled. Its degree of recycling is the highest among plastics.

5. What is commonly used now is becauseextruded tone, with a density of 3.5Kg/m3, thickness 2.0cm, its scientific name is extruded polystyrene insulation panel, a rigid foam panel manufactured by extrusion molding.

Which insulation board for underfloor heating is best

Extruded board.

Extruded boards and foam boards can be used as insulation materials for underfloor heating, but extruded boards perform better in this regard. The higher density and strength of extruded panels provide better insulation and load-bearing capacity, helping to reduce heat loss and increase the efficiency of underfloor heating systems. Extruded panels also have better compressive strength and durability, which can maintain long-term stable performance and reduce the frequency of maintenance and replacement. From a performance perspectiveOverall and long-term benefits, extruded polystyrene panels are the most preferred insulation material in underfloor heating systems. Of course, this is just a personal opinion and different people may have different opinions and preferences.

Is it better to use foam or tiles for underfloor heating?

Insulation panels for underfloor heating are made from a variety of materials. The most common include polystyrene foam boards, extruded polystyrene boards, and extruded polystyrene boards. polyurethane foam board, etc. Insulation boards made of different materials have different characteristics and applicable scenarios, and the selection should be considered according to the specific situation. Polystyrene foam board is a common underfloor heating insulation material. Hehas the advantages of light weight, good insulation performance and practical construction. It is suitable for floor heating insulation, wall insulation and other scenarios. Extruded polystyrene board has the characteristics of high density, high strength and good thermal insulation performance, and is suitable for floor heating insulation, roof insulation and other scenarios. Polyurethane foam board has the characteristics of good thermal insulation performance, good sound insulation effect and practical construction. It is suitable for floor heating insulation, wall insulation and other scenarios. Overall consideration, when choosing floor heating insulation boards, you should choose according to the specific situation and choose the appropriate materials and specifications to achieve the best insulation effect.

HeBetter to have bubbles.

Floor heating foam panels have good impact resistance. The foam board is 98% filled with air, has sufficient capacity to withstand external impacts by changing and recovering its shape, and has low water absorption. Moisture affects the thermal and mechanical properties of the material, and the low water absorption of foam board helps maintain these properties.

The floor heating foam board is a white object made of expandable polystyrene beads containing a volatile liquid foaming agent, pre-expanded by heating then heated and formed in a mold. It has the structural characteristics of fine closed cells. .
