What should I pay attention to when purchasing thermal insulation materials for floor heating panels

A single thermal insulation material is the main body of thermal insulation engineering application, and it needs the cooperation of other materials in the process of use. Such as: foamed polystyrene board, extruded polystyrene board, rock wool board, glass wool board, etc., before using the test content to test the following contents:

1. Water vapor permeability coefficient [ng (pa?m?s)]: This performance determines the performance of water vapor permeability, and to a certain extent, determines the condensation of the wall.

2. Oxygen index: flame retardant type is required, otherwise the fire prevention cannot meet the standard.

3. Apparent density (kg m3): The apparent density of the material affects its thermal conductivity to a certain extent, and the material with unqualified apparent density will directly lead to the decline of its physical properties, such as strength, dimensional stability, etc.

4. Thermal conductivity (w m?)Generally speaking, the laboratory test is tested when the plate is dried to constant weight, and the application of the material is used under the condition that the air contains a certain humidity, so it should be multiplied by a certain coefficient when used; Alternatively, the material can be adjusted to the ambient conditions in which it will be used.

5. Dimensional change rate (mm): The material with a large dimensional change rate will lead to the cracking of the surface layer of the system.

6. Compressive strength (mpa): refers to the compressive stress of the specimen under 10% deformation. It is related to the durability and impact resistance of the surface system.

Do you know what is a floor heating insulation board? Floor heating insulation board is a kind of board used to keep warm by laying air on the floor. Floor heating insulation board is a building material, and now many people will use floor heating treasure board at home.

How to choose a floor heating insulation board? There are also skills when choosing, do you know what the skills of choosing a floor heating insulation board are? Today we will learn about the selection skills of floor heating insulation board, and friends who want to buy floor heating insulation board are best to understand its purchase skills.

1.The importance of underfloor heating insulation panels

As the name suggests, the floor heating insulation board is to prevent the downward transfer of floor heating heat, so as to reduce the ineffective heat loss of the structural layer. To put it simply, it is to pass and rent a material to prevent the heat emitted by the floor heating from heating from warming up to the system itself, but completely dissipating it into the indoor air. It can be seen that only the thermal insulation material with good thermal insulation effect can be up to this task.

At present, the most practical needs on the market are only XPS extruded insulation boards.

2.How to choose the best insulation board?

It should have excellent thermal insulation. The insulation board of floor heating should be in direct contact with the pipe, and when the temperature of the heat medium exceeds 45 °, the material itself will volatilize harmful substances to the human body, which is very unfavorable to human health. For underfloor heating systems that need to be used for months, if the environmental protection of the insulation board cannot be guaranteed, even if there is enough temperature to survive the winter, it is a thing that outweighs the loss.

Therefore, the material of the floor heating insulation board must have good flame retardant performance and environmental protection performance. Make sure that the insulation board uses environmentally friendly materials that do not emit volatile harmful substances, so that you can enjoy both warm and healthy air.

High quality moisture resistance is an important reference factor. Water absorption is an important parameter to measure the insulation board, if the water seeps into the insulation board, at low temperatures, it will lead to freezing, and the insulation material will be directly destroyed. Therefore, it is necessary to choose a thermal insulation board with stable molecular structure of the board, and Bi Zhao can solve the problems of water leakage, permeation, frosting, condensation and other problems of the material in one step.

This will also invisibly improve the service life of underfloor heating.

Superior high-strength compression resistance is important. The compressive resistance of the insulation board is mainly to withstand the load pressure from the floor heating pipes, concrete filling layer and ground activities. If the insulation board does not have enough load-bearing, it can lead to cracks in the infill layer and floor.

The above is the selection skills of floor heating insulation board. When we choose the floor heating insulation board, we should choose some good temperature insulation, because the floor heating insulation board is in direct contact with the underground pipes, if the temperature exceeds 45 degrees, this is very bad. There are many materials for floor heating insulation boards, and some materials will volatilize some harmful gases to the human body, so we must choose some green and healthy ones when choosing.

The strength and compressive resistance of floor heating insulation board are also very important, and we must choose some with good compressive performance when choosing.

In life, when people decorate the house, there are many people who choose floor heating when installing heating, but when paving floor heating, the floor heating insulation board is essential, but people don't know how to buy when they buy, and they don't know much about theseFloor heating insulation panelsWhat are the specifications of the floor heating insulation board, I hope you can refer to it!

One. How to choose a floor heating insulation board.

1.When we buy floor heating insulation board, we should look at the raw materials, which are the key factors in the environmental performance of extruded plastic boards, but they are produced by polystyrene resin. In addition, many extruded plastic panels on the market today are made of ** materials, but few are produced with BASF crystal.

However, as for the red and yellow extruded plastic boards on the market, they are generally similar to the blue extruded plastic boards, but theoretically speaking, the white extruded plastic board (BASF crystal) blue extruded plastic board and the black extruded plastic board.

2.Next, let's talk about the microstructure, but the extruded plastic board is used as a floor heating insulation layer, and its insulation secret lies in its continuous and uniform surface layer and closed-cell honeycomb structure, and the more uniform the bubble cell, the better. There are also white crystal plates with uniform and closed pores, but the blue plate has good cell closures, and there are blackboards without bubbles that are basically not closed.

3.In addition, when buying a shirt, look at the thermal conductivity, the lower the thermal conductivity, the better the heat insulation effect.

Two. What are the specifications of floor heating insulation boards.

1.When buying insulation boards, high-quality hydrophobic and moisture-proof water absorption is an important parameter to measure insulation materials. But the thermal insulation function is reduced after the insulation material absorbs water, and in the case of low temperature, but the inhaled water is easy to freeze, destroys the layout of the thermal insulation material, so that the compressive resistance and thermal insulation function of the board are reduced.

2.The next thing to say is that the layout of high-quality floor heating extruded insulation board should have a high closed cell rate and form a vacuum layer, which will avoid air flow and heat dissipation, but ensure the durability and stability of its thermal insulation function. There are also 20mm thick XPS extruded insulation boards that have been proven by a large number of practices, but their thermal insulation effect is equivalent to 50mm thick expanded polystyrene and 120mm thick cement perlite.

3.At the time of purchase, stability, good corrosion resistance, and high-quality floor heating extruded insulation board should have long-term use, no aging, no differentiation, no harmful substances, its chemical function should be stable, so that it can not be degraded due to water absorption and corrosion, but it can still adhere to its superior function in a long-term high temperature environment.

When decorating the house, when choosing heating, there are many people who choose floor heating, but in the purchase of floor heating must have a good floor heating insulation board, the above article is about how to buy floor heating insulation board and what specifications of floor heating insulation board.

Floor heating is a more common heating equipment in our lives, especially in the northern region, because the heating effect of this equipment is good, so it is very popular with consumers. For underfloor heating, the insulation layer is very critical, and the materials used must be paid attention to. So, what kind of materials are used for floor heating insulation?

What do I need to pay attention to when using underfloor heating? Let's take you to find out.

Most of the floor heating insulation layer is made of extruded plastic board and polystyrene board, of which extruded plastic board is one of the most used. Extruded board is an organic insulation material, its heat resistance coefficient is very high, its structure is honeycomb type, the closed cell rate is more than 99%, can prevent heat loss, and the insulation effect is also very stable.

What should be paid attention to when using underfloor heating.

1. After floor heating, it is best not to lay carpets on the floor, and it is best not to choose no legs for furniture, because these will affect its heating effect and are not conducive to heat dissipation. For the first time to use floor heating in the family, the temperature should not be adjusted too high, and the method of slow heating must be adopted, such as about one degree of heating per hour, so as to avoid deformation and cracking of the floor due to high temperature.

2. When using floor heating, it should be noted that its water temperature should not be too high, otherwise it will affect the service life of its pipes, and at the same time, it will also bring uncomfortable feelings to our human body. Under normal circumstances, the temperature is about 18 degrees Celsius, which is the most comfortable temperature for people.

3. If the floor heating is laid with a wooden floor, then it is best to carry out the ring wheel protection test first. Because the environmental protection of many floors is not very good, if you do not pay attention, then the formaldehyde contained in it will be released in large quantities after heating, affecting human health.

Article summary: The above is all about what materials are used for floor heating insulation and what needs to be paid attention to when using floor heating, I hope it will help you. If you want to know more about it, please stay tuned to Qeeka Home.

How to choose thermal insulation board materials?

1. First of all, we can choose according to the heat resistance of the thermal insulation board material.

At present, the key materials of thermal insulation board in the market can be divided into three types: continuous high temperature, atmospheric pressure and ultra-low temperature. If it is applied in a living environment with a temperature of 100 to 150, it is recommended that you choose a thermal insulation board material with continuous high temperature or atmospheric pressure. If it is applied in an environment with a temperature of about 10 to 30, you can choose ultra-low temperature insulation board material.

2. Secondly, we can choose according to the material of the thermal insulation board.

There are many thermal insulation board materials, and different places can choose different types of thermal insulation board materials. It is recommended that when choosing a thermal insulation board material, it is best to ask whether the physical properties of the material can be consistent with the living environment of the application.
