Insulation board is an essential thing, and this material must be added to any building. However, due to different needs of people, the type of insulation board required also changes. is a little more resistant than an ordinary insulating panel. Before using extruded insulation boards, we must understand them accordingly and then judge their quality based on their characteristics. Only if the extruded board insulation board is of high quality can we use it. Here we will learn more about how to judge the quality of extruded board insulation board.
How to judge the quality of extruded insulation panels
Look at the raw materials
The panel extruded is made from polystyrene resin. But many extruded panels available on the market are now made from recycled materials. Very few are producedby BASF crystals. From the perspective of raw materials, the ranking of advantages and disadvantages of extruded panels is as follows: white crystal extruded panel > blue extruded panel > black extruded panel. There are also red and yellow extruded panels on the market, which are generally similar to blue extruded panels. The next three types are BASF crystal, advanced recycled polystyrene and recycled polystyrene.
Look at the microstructure
One of the main uses of extruded panels is as an insulation layer for underfloor heating. The secret of extruded insulation boards lies in their continuous, uniform surface layer and closed-cell honeycomb structure. The more uniform the cells, the better. The next three microstructures are the white crystal plate, the blue plate and the black plate. The cells of the white crystal panels shave uniform and closed. The blue plate bubbles are well sealed. The table has no cells and is basically not closed.
Look at the effect of direct pressure with your hand
The image below visually shows the effect of different extruded boards after been pressed with your fingers. The white crystal plate is almost invisible to the naked eye after being pressed. Good blue plates have smaller prints. Dents on low quality blue boards are obvious. The direct damage to the painting was the most serious.
Look at the lifespan
The lifespan of a house is generally more than 50 years. As a hidden project of the house, if the underfloor heating cannot last in the house, this means that it will be reinstalled while in use. Tests have shown that the lifespan of white crystal panels can reach 50years. The lifespan of good blue boards can reach 30 years, and bad blue boards can generally be used for 15 years. The lifespan of blackboards is generally 5 years.
Look at environmental protection
Personally, it is recommended not to use fireproof panels for home decoration, because the panels Extruded flame retardant HBCD (HBCDD) is not environmentally friendly. White crystal panels are made from 100% new materials and are the most environmentally friendly. The blue tables contain certain additives. The board is made entirely from recycled materials. Eco-friendly white crystal board > blue board > black board.
Look at the energy savings
As shown in the floor heating structure diagram, minus the heat dissipation down the heaterby the ground, the greater the energy savings. It is. Thanks to the bubbles, the energy saving of the three is: WhiteCrystal board>Blue board>Black board.
Look at the apparent density
The apparent density is an important indicator of extruded panels. Directly linked to compressive strength. The bulk density of white crystal panels for underfloor heating is 35-36 KG/m². 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 almost blue panel is approximately 30 kg/m². The apparent density of blackboards is generally around 25 kg/m².
The quality of the extruded panel insulation panel depends not only on its own quality,but also the stability of its performances. Only when it meets various requirements can it be used normally. Since the extruded board insulation board is intended to ensure the safety of people, there can be no difference in its quality. People should also check this clearly when choosing. They cannot be greedy for the low cost of the panel and delay its use. Additionally, extruded board insulation boards are relatively hard, so take extra care during transportation to avoid accidental damage to the boards.
Which is better, an underfloor heating module or extruded panels?
When the house is being renovated, many people now install an underfloor heating. they will use. I went for Floor heating panels, but when I bought I didn't know what fabricant was the right one. Also, when I bought, I didn't know how to choose. I didn't know much about it. So, what about floor heating panel manufacturers? What are they? We will then present them to you and hope that you can refer to them.

2. How to choose floor heating panels
1. When purchasing floor heating panels, you should also look at the raw materials which are the key factor in the environmental performance of the heating panels. extruded panels. They are made of polyethylene. Made from styrene resin. ButMany 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. But in theory, white extruded panel (BASF crystal), blue extruded panel and black extruded panel.
2. When purchasing underfloor heating panels, you should also look at the microstructure of the extruded panels intended to be used as insulation layers for underfloor heating. The secret of its insulation lies in its continuous and uniform surface layer and its closed cells. Honeycomb structure and cells. The more uniform they are, the better. However, the cells of the white crystal array are uniform and closed, the cells of the blue array are well sealed, and the black array has no cells and is basically not closed.
3. When purchasingFor underfloor heating panels, you also need to look at the thermal conductivity. The lower the thermal conductivity, the better the thermal insulation effect.
4. When purchasing underfloor heating panels, you need to look at the bulk density. Bulk density is an important indicator of insulation boards for underfloor heating. Directly linked to compressive strength. The bulk density of white crystal panels for underfloor heating is 35-36KG/m_. But the specific weight of a good blue plate is also this value. There is also a problem with the blue plate raw materials. Even if the bulk density is the same, the quality of the white crystal plate is still better than that of the blue plate. But the apparent density of the slightly lower blue plate is about 30 kg/m_. The apparent density of blackboards is generally around 25 kg/m².
When purchasing underfloor heating panels, who are the manufacturers and how to choose them? The article above explains which underfloor heating panel manufacturers exist and how to choose underfloor heating panels.
How thick is the extruded panel used for underfloor heating? How much per square meter?
Floor heating modules and extruded panels are two commonly used materials in underfloor heating systems. Although they are different in usage, features and price, they each have their own advantages and disadvantages, and they can all be selected according to actual needs.
1. Floor heating module
Floor heating modules are usually made from materials such as polystyrene (EPS) or polypropylene (PP) and are used to attach floor heating pipes the ground. Heating modulesunderfloor installation are easy to install and maintain, so they are widely used. Specifically, the floor heating module mainly has the following advantages:
Advantages:
-Easy to install and can effectively fix floor heating pipes;
p>
-Good sound insulation performance, can effectively isolate noise;
- High thermal conductivity, able to transfer heat quickly;
- Holes can be drilled as required for easy switching of pipe directions;
Disadvantages:
- The underfloor heating module has a small coverage area and is easily strained;
p>
- It has insufficient pressure resistance and is prone to deformation or cracking.
2. Extruded panels
Extruded panels are generally made of materials such as polystyrene, polyurethane and polyphenylene carbonic acid and are usedused as insulating materials. pressPlastic panels are characterized by light density, good thermal insulation properties, high bearing capacity and pressure resistance.
Advantages:
-Light density and easy to install;
-Has good thermal insulation performance;
-Excellent load-bearing performance, strong pressure resistance;
- Excellent properties such as anti-aging, anti-corrosion, water resistance and flame retardancy.
Disadvantages:
-Extruded boards are not suitable for direct installation on the ground;
-The price is relatively high;
In short, choose whether the floor heating module or the extruded panel should be based on actual needs. For example, when the material of the floor heating system is mainly used to fix the pipes, the floor heating module should be used for thermal insulation. and the insulationrmic, the extruded panel must be used. In addition, when choosing products, you should also pay attention to factors such as product specifications, quality and professional services.
