1. Foam boards are non-toxic when spread 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:
The effects of use of foam panels:
1. Protect the main structure of the building and extend the life of the building. Since the external insulation places the couche insulating 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 present 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. 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 increasea, further improving the thermal insulation performance of the wall.

Should we use extruded board or foam board for underfloor heating?
Can it be used for floor heating?
In daily life, people usually use foam boards to prevent heat loss from the floor
< p>Because the biggest advantage of using foam boards is that the foam can be recycled and reused. Because foam is a recycled material, so in terms of floor heating maintenance cost, the cost of foam 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 ae waterproof function, which is beneficial and harmless to the whole project. In addition, the thermal conductivity of the 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 board has the ability to reboundWhich underfloor heating insulation board 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 extruded board has higher density and strength and can provide more good thermal insulation properties and bearing capacity, which help reduce heat loss and increase the efficiency of underfloor heating systems. Extruded panels also have better compressive strength and durability, whichwhich 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 may have different opinions and preferences.
How much does underfloor heating cost in Changzhi! There are about more than 200 square meters of house, and it is the village's own house! What size boiler is best to install?
Insulation panels for underfloor heating are made from a variety of materials. The most common panels include polystyrene foam panels, extruded polystyrene panels, polyurethane foam panels, etc. Insulating panels made from different materials havedifferent 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. It has 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.
4 meters per square meter. The spacing is 30 centimeters, and the price is about two yuan per meter per meter. Don't forget to lay foam panels under the underfloor heating. The pressure is around 18 to 20 kilograms. There is also anti-radiation paper on it. The longest length of each road does not exceed 70 meters. The heat for each route is approximately 45 watts and a pipeline circulation pump must be added. Because it is not a mechanical cycle, the copper of the water separator is about 40.
