Extruded polystyrene panel.
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 the perspective of overall performance 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 mayhave different opinions and preferences.
Can foam boxes be used for underfloor heating?
When this material ages, external pressure changes and construction is inappropriate, he collapses.
1. Material Aging: Over time, underfloor heating foam panels can lose their original strength and stability due to material aging, leading to collapse.
2. External pressure changes: Unstable water pressure in the floor heating system or pressure changes in the external environment can affect the foam board, causing its structure to be damaged and collapse.
3. Improper construction: If the underfloor heating foam board is installed incorrectly, for example by setting the nails too tightly or using inappropriate force, it may cause damage and effolay the foam board.
Is foam board toxic when used under underfloor heating?
Can it be used for underfloor heating?< /strong>
People usually use foam panel in daily life to prevent heat loss from the ground
Because the biggest advantage of using foam panel foam is that foam can be recycled and reused, because foam is a recycled material, so in terms of the cost of maintaining the house underfloor heating, foam The cost of the board is easy to use and affordable. In addition, because the main material of foam board is foam, so its quality is relatively light and the absorption capacity of foam is not good, which means it can avoid the absorption burden by the cement floor. That is to say, it acts as a waterproof function, which is beneficial and harmless to the whole project. From plus, the thermal conductivity of foam board is relatively low, so it has super impact resistance if the interior of the floor is almost. filled with air, then this type of foam boards can achieve the ability to bounce back.
How thick is the foam board needed to lay underfloor heating?
1. non-toxic when placed under underfloor heating.
2. Generally, good quality (XPS) foam boards are non-toxic. Insulation boards made from new materials, such as white crystal boards, do not contain toxic substances such as formaldehyde and ethylbenzene. underfloor heating released.
3. A polystyrene insulation board with a thickness of 10 to 20 mm is used under electric underfloor heating. The temperature of the electric heating wire is around 60 degrees, which is non-toxic.

The effects of using foam boards:
1. Protect the main structure of the building and extend the life of the building. Since external insulation places the insulating layer outside the structure, it reduces the pressure caused by structural deformation due to temperature changes and reduces the erosion of the structure by harmful substances in the air and ultraviolet rays.
2. Effectively eliminate “thermal bridges”. In the past, interior insulation was used and “thermal bridges” were inevitable. However, insulating exterior walls can effectively prevent the appearance of thermal bridges and avoid condensation.
3. To improve the moisture content of the wall, a vapor barrier is usually required for internal insulation. However, the temperature permeability of external insulation materials is generallyalally much stronger than that of the main structure. There is no need to install a vapor barrier inside the wall. Condensation will occur and the temperature of the entire wall in the structural layer will increase, further improving the thermal insulation performance of the wall.
Baidu Encyclopedia_Polystyrene Foam Board
Normal 20mm foam is enough to be used as insulation material, thermal conductivity is very important. 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 water absorption rate of the foam board is low, its anti-penetration ability is good, and it can also be recycled. Its degree of recycling is the highest among plastics. However, foam boards have poor strength and bearing capacity andare prone to cracking if used as insulation for underfloor heating, they need to be reinforced, which is more troublesome.
Chinese floor tiles generally use prefabricated or cast-in-place tiles. The sound insulation effect is extremely poor. People climbing stairs will affect the underfloor heating which is used to increase the insulation layer. a very good sound insulation effect and can reduce noise pollution.

Construction precautions of concrete filling layer:
1. The underfloor heating pipe has been installed and the hydraulic system. the pressure test was successful. The construction of the concrete infill layer must be completed within 48 hours;
2. The construction of the concrete infill layer must be undertaken by qualified construction parties, and our unité will cooperate closely;
3. The construction of concrete filling layer During construction, the water pressure in the heating pipe should not be less than 0.6 MPa. During the maintenance of the filling layer, the system water pressure should not be lower. greater than 0.4 MPa;
4. The filler layer is used to protect plastic pipes and make the floor a uniform temperature structural layer. Usually it is pisolite concrete, the grain size of the stones should not be more than 10 mm, the volume ratio of cement mortar should not be less than 1:3, and the degree of strength of the concrete should not be less than C15. The thickness of the filling layer should meet the design requirements, and the flatness should not exceed 3mm;
5. The underfloor heating system must install expansion joints at the vertical intersections of walls, columns andhe doors; , etc. with the ground, and the width of the expansion joints must not be less than 10 mm. The width of the expansion joint must not be less than 8 mm.
