Can be used for floor heating
In daily life, people usually use foam boards to prevent heat loss through the floor
Due to the use of foam boards The biggest advantage is that the foam can be recycled and reused, because the foam is a recycled material, therefore in terms of the cost of maintaining the house and underfloor heating, foam board cost 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. In addition, the thermal conductivity of foam board is relatively low, so it has super resistance toshocks if the inside of the floor is almost. filled with air, then this type of foam boards can achieve the ability to bounce back.
Is it better to have foam or flat floor heating?
1. Foam boards are not. -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.
Detailed information:
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 generally much stronger than that of the main structure. It is not necessary to install a pare-steam 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.

It is better to have foam.
Floor heating foam panels have good impact resistance. The foam board is 98% air filled, 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 made of expandable polystyrene beads containing a volatile liquid foaming agent, which are heated and pre-expanded in a mold. The white object formed by heating has the castructural characteristics of fine closed cells.
