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. Insulation boards made of different materials have different 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. The 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.it and other scenarios. Polyurethane foam board has the characteristics of good heat 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.
What materials are used for insulation panels for underfloor heating? How to choose insulation boards for floor heating?
The thickness of insulation boards for floor heating is generally 20mm to 50mm. The specific thickness must be determined. according to the actual situation. Generally, the thicker the underfloor heating insulation board, the better the performance.insulation, but the thicker the thickness, the higher the cost. Therefore, when choosing an insulation board for underfloor heating, the thickness should be determined accordingly. the actual situation to achieve the best insulation effect.
What type of insulation board is typically used for underfloor heating in high-rise buildings? How thick and dense is it?
Nowadays, most houses install underfloor heating, but few people know about insulating panels for underfloor heating. Underfloor heating insulation boards play a decisive role in the underfloor heating system and are an important consideration when purchasing underfloor heating. So, what should consumers pay attention to when it comes to underfloor heating insulation panels? Let’s discover together the insulating panels for underfloor heating.
What materials are used for underfloor heating insulation boards?
Common insulation boards currently on the market include extruded boards and polystyrene boards. In terms of performance and product quality, extruded insulation boards. Cardboard is better than polystyrene cardboard. The choice of insulation board material is also very important.
1. Extruded board, also called XPS board, is the third generation of rigid foam insulation material. XPS board is a board composed of extruded polystyrene resin and other additives, with a continuous and uniform surface layer and a closed-cell honeycomb structure. The XPS card overcomes the complicated production process of EPS cards and provides superior performance that EPS cards cannot replace.
The thermal conductivity of the extruded panel is only 0.028 W/(m·k), which islower than that of foam board, so the heat insulation effect is better than that of foam board. Likewise, the extruded panel has very low water absorption and very good resistance to humidity and water. Different from foam boards, extruded boards have high strength, good pressure resistance, are not easily damaged, are easy to transport, have stable performance, and are environmentally friendly and harmless.
2. Floor heating foam board, also known as polystyrene foam board and EPS board, is made of expandable polystyrene beads containing volatile liquid foaming agent. It is heated and pre-expanded in a mold. White objects are mainly used for building wall and roof insulation, composite panel insulation, cold storage, air conditioning, vehicle insulation,ships, etc., and have a wide range of uses.
How to choose floor heating insulation board
1. Look at the raw materials
The raw material is the key factor in the environmental performance of the extruded panel. , which is produced from polystyrene resin. But many extruded panels on the market are now made from recycled materials, and few are produced by BASF Crystal. As for the red and yellow extruded boards on the market, they are generally similar to the blue extruded boards. Theoretically speaking, white extruded panel (BASF crystal) > blue extruded panel > black extruded panel
2. Look at the microstructure
Extruded board is used as an insulation layer for underfloor heating, its thermal resistance The secret of insulation lies in its continuous and uniform surface layer and honeycomb structure closed-cell bee. Plus the celsThe more uniform, the better. The cells of the white crystal board are uniform and closed, the cells of the blue board are well sealed, and the black board has no cells and is basically not closed.
3. Look at the thermal conductivity coefficient
The lower the thermal conductivity coefficient, the better the thermal insulation effect.
4. Look at the apparent density
The apparent density is an important indicator of insulating panels for underfloor heating. Directly linked to compressive strength. The bulk density of white crystal panels for underfloor heating is 35-36KG/m_. The specific weight of a good blue plate also corresponds to this value. However, due to the raw material of the blue plate, even if the bulk density is the same, the quality of the white crystal plate is still better than that of the blue plate. The apparent density of the purlinto almost blue is approximately 30 kg/m_. The apparent density of blackboards is generally around 25 kg/m_.
Can foam boxes be used for underfloor heating?
1. Extruded boards, also called XPS boards, are the third generation of rigid foam insulation materials. It offers superior performance that cannot be replaced by EPS cards. Its density is 35Kg/m3 and its thickness is 4.0cm.
2. Foam board for underfloor heating is also called polystyrene foam board and EPS board. It is mainly used for building wall and roof insulation, composite panel insulation, cold storage, air conditioning, vehicle insulation, ship insulation, etc. .Very versatile.
3. Nowadays, almost all underfloor heating insulation boards use XPS (extruded polystyrene plastic board). The Avasntages are low thermal conductivity and high compressive strength. also good and bad XPS cards. The most obvious is the use of raw materials. The more recycled materials used, the worse the quality of the XPS and the lower the cost.
4. To be used as an insulating material, thermal conductivity is a very important criterion. The foam board has an independent bubble structure, low thermal conductivity, generally less than 0.039 W/(m·k), low density and light weight. In addition, the surface of the foam board has low water absorption, good anti-penetration ability and can be recycled. Its degree of recycling is the highest among plastics.
5. What is commonly used now is an extruded polystyrene panel, with a density of 35 kg/m3 and a thickness of 2.0 cm. Its scientific name is an extruded polystyrene insulation panel, manufactured byextrusion molding. foam board.
Can be used for floor heating
In daily life, people usually use foam boards to avoid heat heat loss through the groundp>
Because the biggest advantage of using foam board is that the foam can be recycled and reused. Since foam is a recycled material, so in terms of the cost of home maintenance and floor heating, the cost of foam board is easy. 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 a waterproof function, which is beneficial and harmless to the whole project. Additionally, the thermal conductivity of foam board is relativement weak, so it has super resistance to shocks if the interior of the floor is almost. filled with air, then this type of foam boards can achieve the ability to bounce back
