When choosing underfloor heating xps insulation board for ground heating, you need to consider some important factors to ensure that they meet your needs.
Here are some suggestions:
Underfloor heating xps insulation board is usually made of polystyrene (EPS) or extruded polystyrene (XPS). The price of EPS is lower, but XPS is more durable and water resistant. Choose the right material according to your budget and requirements.
The thickness of the extruded plate is usually between 20 mm and 100 mm.
Choosing the appropriate thickness depends on the design and performance requirements of your floor heating system.
Ensure that the underfloor heating xps insulation board has sufficient pressure strength to support floor heating pipes and flooring materials. In general, the pressure strength of the extruded board should be able to withstand the normal human activities and the weight of furniture.
Choose the underfloor heating xps insulation board with low thermal conductivity to improve the efficiency of the floor heating system. XPS usually has lower thermal conductivity and therefore performs better in terms of thermal insulation.
If your basement is prone to moisture or water problems, choose an underfloor heating xps insulation board with good humidity and moisture resistance. XPS usually has this advantage over EPS.
Consider choosing environmentally friendly underfloor heating xps insulation board to reduce the impact on the environment. Some manufacturers offer recyclable extruded panels.
Underfloor heating xps insulation board should be easy to cut and install in order to adapt to the design of the floor heating system. Make sure the extruded board of your choice is easy to process and install.
the price of the underfloor heating xps insulation board varies according to material, thickness and brand. Be sure to select products that meet your budget and meet performance requirements.
Choose underfloor heating xps insulation board from well-known brands or experienced manufacturers to ensure the quality and performance of the products.
When choosing underfloor heating xps insulation board, it is best to consult a professional floor heating designer or contractor to ensure that your choices match the specific requirements of your floor heating system.
Underfloor heating xps insulation board is widely used as insulation layer in floor heating laying because of its high quality of heat preservation, water absorption, compression resistance, flame retardancy and so on.
However, how many people know that extrusion boards, as auxiliary materials for floor heating, can be divided into two categories: one is raw material extrusion boards made of new materials, and the other is recycled materials made of waste plastics.
As the price of the raw material underfloor heating xps insulation board is very high, and the qualified extruded board equipment is expensive, at present, many manufacturers are inferior. Many of the popular extruded boards in the market are made of recycled plastic.
The sources of recycled plastics include: medical plastic garbage, plastic lunch boxes, electrical shells, foreign garbage and so on. However, due to the low level of domestic plastic recycling enterprises, the vast majority of enterprises are still in the state of small workshops, unable to distinguish which plastics are toxic and can not be recycled.
Therefore, the underfloor heating xps insulation board of recycled materials is full of heavy metals, toxic PVC and so on. These ingredients will release carcinogens such as hydrogen chloride, chlorine gas, hydrochloric acid and dioxins under high temperature. The release of these substances will produce strong irritation to the human eyes and respiratory tract mucosa.
Mild cases can cause headache, nausea, allergies and other symptoms, severe cases can cause damage to the human liver and nervous system. The water absorption rate of nourishing harmful bacteria is an extremely important parameter to measure whether the extruded board is of high quality.
Because the molecular structure of polystyrene itself is not absorbent, the molecular structure of the high-quality underfloor heating xps insulation board is stable and there is no gap, which solves the problems of water leakage, infiltration, frosting and dew of other materials.
However, the inferior underfloor heating xps insulation board contains a variety of impurities. Under the action of capillarity, water gradually seeps into the interior of the plate. Water is an important condition for mold growth. Porous materials will form a "hotbed" for mold growth after absorbing water, and the harm to people living in it is self-evident.
Energy consumption and thermal waste the thermal conductivity of high-quality materials is 0.026. The thermal conductivity of inferior materials is 0.040, which will directly affect the energy-saving effect of the whole floor heating system and the later operation cost of the floor heating system.
Moreover, after the inferior underfloor heating xps insulation board absorbs water, the inhaled water is easy to freeze at low temperature, which destroys the structure of the insulation material, thus reducing the insulation performance of the board.
Moisture content is an important factor affecting the thermal insulation effect of insulation board.
For every 1% increase in moisture content, the thermal insulation effect will be reduced by about 10%. In the process of land subsidence recovery and reconstruction, polystyrene needs to be remelted at high temperature, which will lead to the fracture of a large number of molecular chains and significantly reduce the strength of the extruded plate.
In order to reduce the cost, many small factories will try their best to reduce the density of the underfloor heating xps insulation board, which directly leads to the low compression resistance of the underfloor heating xps insulation board.
The underfloor heating xps insulation board has storage requirements, that is, the product can only be used after 21 days of storage, so that the water vapor can be fully evaporated to achieve the best product condition. However, the finished foam board takes up a lot of space.
The manufacturer has been storing for such a long time. A small number of powerful manufacturers will build a drying chamber to solve this problem, and a large number of small factories will use it directly.
In the process of using this inferior extruded board, under the action of the weight of furniture, it will lead to ground subsidence and cracking of concrete layer. The flame-supporting underfloor heating xps insulation board has the advantage of "flame retardant" because it contains additive flame retardant.
However, in the recovery process, flame retardants are easy to volatilize and not easy to retain. Some manufacturers do not even add flame retardants at all in order to save costs. As a result, the original "flame retardant" became "flammable".
