Abstract: In traditional floor heating materials, the basic heating and insulation materials are all XPS extruded boards. It is also proved that the high quality XPS extruded board meets the requirements of environmental protection, thermal conductivity, compressive strength and moisture permeability. The demand, the best quality on the market is the white crystal plate. However, some friends have found that in addition to the common XPS extruded board, there is a similar thermal insulation board with a groove. Is the grooved floor heating board good or not? Source: Insulation Engineering Network In traditional heating and auxiliary materials, the basic heating and insulation is XPS extruded board. It is also proved that the high quality XPS extruded board meets the needs of floor heating and insulation regardless of environmental protection, thermal conductivity, compressive strength or moisture permeability coefficient. At present, the best quality on the market is the white crystal plate. However, some friends have found that in addition to the common XPS extruded board, there is a similar thermal insulation board with a groove. Is the grooved floor heating board good or not? This kind of self-grooved insulation board is called pre-groove insulation board, which is a kind of product which evolved from the traditional heating auxiliary material to the floor heating module conversion process. It is still very different from the real floor heating module. Pre-groove insulation board Compared with conventional floor heating panels, especially white crystal plates, there are still many differences. 1. Different raw materials: The pre-groove insulation board on the market has XPS and EPS materials, and most of the pre-groove insulation boards are color or even black, containing different degrees of recycled old materials; commonly used XPS floor heating In the thermal insulation board, the white crystal plate is produced by using the crystal grade new material, which is safe and environmentally friendly. If you purchase pre-groove insulation boards, it is recommended to buy "white crystal grade". 2, the process is different: the commonly used XPS floor heating insulation board is extruded, and the EPS pre-groove insulation board is made by heating and molding in the mold after foaming. Due to the process limitation of XPS, it is impossible to make the shaped sheet, so XPS-made pre-grooved insulation boards require secondary processing to form grooves, so the cost increases. 3, heat dissipation effect: XPS is better than EPS in terms of thermal conductivity. Taking white crystal plate as an example, its thermal conductivity is ≤0.028w/(mk), EPS is difficult to reach; and due to pre-groove insulation The shape of the board is characterized by the fact that the surface must be coated with a heat-conducting aluminum plate. If it is not added, the contact area between the floor heating pipe and the heat-insulating plate will be large, so that the heat is “locked” in the heat-insulating plate, and the heating effect will be reduced. 4. Different construction methods: The commonly used XPS floor heating insulation board is suitable for wet floor heating construction. After laying and coiling, it is necessary to carry out concrete backfilling. It is a floor heating with heat storage layer. The pre-groove insulation board is suitable for dry floor heating. After laying and coiling, it is not necessary to backfill, and the floor tiles can be directly laid.
