Is foam board toxic when used under underfloor heating?

Introduction Is foam board toxic when placed under ground heat? 1. Foam board is non-toxic when laid under ground heat. 2. Generally, good quality (XPS) foam boards are non-toxic. Insulation panels made from new materials are as white as possible.

Is foam board toxic when used under underfloor heating?

1. Foam boards are non-toxic when spread under underfloor heating.

2. Generally, good quality (XPS) foam boards are non-toxic. Insulation boards made of new materials, such as white crystal boards, do not contain toxic substances such as formaldehyde and ethylbenzene when used. 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 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 on the outsider of 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. 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 thethermal insulation performance of the wall.

Is it better to have foam or flat floor heating

Plate extrusion.

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 sont 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.

It's better 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..
