Is the foam board toxic? Many consumers are concerned about the problem. The foam board is made of expandable polystyrene beads containing a volatile liquid foaming agent and heated to form a white object that is heated in a mold after heating. It has a fine closed-cell structure. Characteristics, mainly used for building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicles, ships thermal insulation, floor heating, decorative carving and other uses are very wide. The following small series for everyone to introduce foam board toxic and foam board advantages and disadvantages.
Is the foam board toxic?
Under normal circumstances, use and select the brand of the product is completely not worried about its toxic, but because of the superior thermal insulation of the product, in the long-term use, it is easy to breed some bacteria, and when using it, friends should also avoid Use in high-temperature, flammable situations because the foam board emits a lot of toxic fumes once burned.
Normal use under normal environmental conditions is not toxic, friends can rest assured, but it should be noted that although this product has a certain flame-retardant properties, but it may still burn, smoke produced when burning toxic, for the bubble The use environment of the board must be fully understood to ensure the use of security.
Foam board advantages and disadvantages
advantage
1, the quality is very light. Domestic regulations require a bulk density of foam board of 18-22 kg/m3, while European regulations require a bulk density of only 15 kg/m3;
2, low thermal conductivity. The structure of the foam plate filled with air-cluster holes impedes the propagation of air, and its thermal conductivity is below 0.039w/(m·k);
3, can be recycled. The recovery of foam boards is the highest in plastics.
Shortcomings
1, construction trouble. Before the laying of the foam board, it is necessary to hang the net, which is cumbersome and prolongs the construction period;
2, poor strength. Foam boards are prone to cracking, and insulation layer shedding is common.
3, poor bearing capacity. Due to the limited strength of the foam board itself, it is necessary to strengthen the floor when laying floors;
4, the quality of instability. The foam board needs to be placed for a period of time before leaving the factory, and it can be used only when it reaches the mature period. The quality is difficult to guarantee;
5, flammable and toxic. The foam board is flammable, and the smoke produced by the combustion is toxic. Even if the flame retardant is added, the burning property can only reach Class B.
The role of foam board
1. Protect the main structure of the building to extend the life of the building. Since the external thermal insulation is to place the thermal insulation layer on the outside of the structure, the stress caused by the structural deformation caused by the temperature change is reduced, and the harmful substances in the air and the ultraviolet rays to the structural erosion are reduced.
2. Efficiently eliminate “thermal bridges†In the past, internal thermal insulation was used. “Heat bridges†are difficult to avoid. External wall insulation effectively prevents the generation of thermal bridges and avoids condensation.
3, to improve the tidal temperature of the wall, the general insulation needs to be set up vapor barrier layer, and the thermal insulation performance of the external insulation material is far stronger than the main structure, in the wall does not generally occur condensation, structural layer The entire wall temperature has been increased to further enhance the insulation performance of the wall.
4, is conducive to the room temperature to maintain stability, the use of external insulation, due to the wall of the heat storage capacity of the structural layer inside the wall, is conducive to room temperature stability.
5. Increase the area of ​​use of the house. You can avoid secondary decoration damage to the insulation.
Editor's summary: Were you concerned about the toxicity of the foam board and the advantages and disadvantages of the foam board, I hope to be helpful to everyone. If you want to know more related information, you can pay attention to this website information.
