How to choose thermal insulation materials, whether in the south or the north, the temperature is getting higher and higher, which makes the temperature on the top floor of the room get higher and higher. If the roof is not insulated, many people who live on the top floor will not be able to stand the high temperature at all. Let's share how to choose thermal insulation materials.
1 How to choose roof insulation materials?
1, which kind of roof insulation material is better? The thermal conductivity of rubber powder polystyrene particle insulation slurry is 0.057-0.06, which has good flame retardancy, unsatisfactory waste recycling insulation effect and high construction requirements.
2. What kind of roof insulation material is better? The thermal conductivity of rock wool board is 0.04 1-0.045, which is fire-proof, flame-retardant, hygroscopic and poor in heat preservation.
3. What kind of roof insulation material is better? The thermal conductivity of perlite slurry is 0.07-0.09, which has good fire resistance, poor high-temperature insulation effect and high water absorption.
4. What kind of roof insulation material is better? The thermal conductivity of expanded polystyrene board (EPS board) is 0.038-0.04 1, with good thermal insulation effect, low price and slightly poor strength.
5. What kind of roof insulation material is better? The thermal conductivity of extruded polystyrene board (XPS board) is 0.028-0.03, which has good thermal insulation effect, high strength and high humidity resistance, and the surface needs to be treated during construction.
6. What kind of roof insulation material is better? Polyurethane foam material has thermal conductivity of 0.025-0.028, good waterproof performance, good thermal insulation effect, high strength and high price.
How to choose roof insulation materials?
1, select the roof insulation material.
Pottery clay and cement tile: Pottery clay tile is a common material for high-grade houses or places prone to fire. Although pottery tiles are twice as expensive as good asphalt colored tiles, they also have a long life. Tiles can have different colors, materials and patterns. Clay, concrete and metal are all common materials.
2, choose the roof insulation materials
Coil roofing: In Europe and America, most low-slope commercial roofs adopt coil roofing system. Almost all waterproof materials, such as TPO, PVC and EPDM, are used in roofing systems. There are also modified asphalt waterproofing membrane roofs in Europe.
3, choose the roof insulation materials
Roof tiles: Asphalt, fiberglass and wood are typical roof tiles used as roof materials. Most building codes and manufacturers require the roof to have a small slope of 4/ 12 with a layer of roof gasket material.
I believe everyone has a certain understanding of what is a good roof insulation material. There are many kinds and brands of roof insulation materials. At this time, it is very important to choose roof insulation materials according to different regions, because only by choosing suitable materials can better insulation effect be achieved. But in general, in order to ensure the quality of products, we need to choose brand products.
How to choose thermal insulation materials? 2 What kinds of insulation materials are there?
1. Thermal insulation paper: IT is often used for small IT electronic products and household appliances, but rarely used for building thermal insulation. Fiber GC- 10 ~ 50 series thermal insulation paper has a thermal conductivity of 0.027 W and a thickness of 0.4 ~ 5 mm, which is white and paper-like, and has the advantage of ultra-thin.
2. Glass fiber cotton board/felt: used for household appliances, pipes, etc. The thermal conductivity is 0.035 Watt-meter, the thickness is 3 mm ~ 5 mm, it is white, divided into hard board and soft felt, and it has glass fiber structure.
3. Polyurethane foam board (PU/PIR): the thermal conductivity is 0.02 ~ 0.035 Watt-meter, multi-color, hard and brittle, and the thickness is 10 mm ~ 200 mm. ..
4. Centrifugal stripping of fiber cotton/rock wool: generally used in construction industry, computer room, warehouse, etc. Normal thermal conductivity is 0.038W, thickness is 30 ~ 200 mm, and it is yellow.
5. Micro-nano insulation board: thermal conductivity is 0.02 W/m, which is resistant to high temperature and is mostly used in high temperature environment.
6. Aerogel felt: It can be customized into a rigid plate-like material as required, which is suitable for the insulation of equipment and pipelines. At room temperature, the thermal conductivity is 0.018w/(k m), the thickness is 2 mm ~ 10 mm, and it is white or blue, which is a flexible felt.
How to choose thermal insulation materials for home improvement
1. Depending on the temperature range of the material.
According to the temperature range of materials, there are low temperature insulation, medium temperature insulation and high temperature insulation. If low-temperature thermal insulation materials are selected, materials with a temperature about 100- 150℃ higher than the long-term use temperature can be selected.
2. According to the form of thermal insulation material
There are many forms of heat insulation materials, such as cotton, paper, felt, board, special-shaped parts, textiles and so on. Due to different types of physical characteristics, these different forms of thermal insulation materials will be different.
3. Calculate the price cost
After selecting the range of materials to be used, the next step is to buy, and then you need to calculate the cost of the price and try to buy materials with good cost performance.
Generally speaking, the selection of thermal insulation materials is to select thermal insulation materials whose shape, physical characteristics, chemical characteristics and thermal insulation performance meet the use environment and environmental protection grade meet the design requirements according to the use environment, and finally determine the thermal insulation materials to be used after accounting the cost.
Finally, the article concludes that the insulation materials used in home decoration are insulated because the materials themselves have such special properties, so after understanding the insulation materials, we can easily and quickly choose insulation products according to the purchasing skills I summarized above.
How to choose 3 1 as thermal insulation material depends on temperature resistance.
According to the temperature range of materials, there are low temperature insulation, medium temperature insulation and high temperature insulation. If low-temperature insulation materials are selected, materials with a temperature about 100- 150℃ higher than the long-term use temperature can be selected.
Step 2 choose famous brands
Some manufacturers produce unqualified and unqualified thermal insulation products for temporary benefits, and using unqualified thermal insulation materials will cause great harm. Therefore, when choosing thermal insulation materials, we must choose regular manufacturers.
Step 3 look at the materials
There are many forms of heat insulation materials, such as cotton, paper, felt, board, special-shaped parts, textiles and so on. Due to different types of physical characteristics, these different forms of thermal insulation materials will be different.
2. What are the brands of thermal insulation materials?
