What are the recommendations for exterior wall insulation materials for the renovation of old reside

Most of the old residential areas were built in the 20th century, and the building envelope was designed.

It is too simple, the building insulation, heat insulation and other conditions are very poor, and it is extremely important to do a good job in the energy-saving renovation of the building exterior wall, which is extremely important for the effective improvement of the thermal insulation and thermal insulation capacity of the building exterior wall, and it is also an important way to effectively reduce the energy consumption of the building. Therefore, it is necessary to do a good job in the design of external insulation of the exterior wall of the old community to become a building energy conservation and emission reduction.

important means.

At present, there are many types of insulation materials in China's market, which can be divided into two categories: organic insulation materials and inorganic insulation materials according to the different materials of insulation materials. In the field of construction, the commonly used inorganic insulation materials mainly include rock wool.

Expanded perlite, polystyrene particle insulation mortar, foam glass panel, foamed cement board, calcium silicate.

products, etc. Commonly used organic insulation materials mainly include polyurethane, ordinary molded polystyrene board, phenolic foam, etc.

among othersPolyurethane insulation boardBecause of its good thermal insulation effect and strong flame retardant performance, it is widely used in the construction field.

Unique waterproofing properties

Polyurethane insulation board is a microporous foam with a dense structure and a closed cell rate of more than 92%, so it has high water vapor permeability resistance and good impermeability. A large number of application practices have also proved that polyurethane insulation board is a high-quality material that does not absorb moisture.

Excellent thermal insulation performance

Polyurethane insulation panels have a very low thermal conductivity.

Only k) or so.

Anti-corrosion, anti-corrosion, good aging resistance

Polyurethane insulation board is resistant to general solvents such as gasoline and benzene and dilute concentrations of acids, alkalis and salts.

It has good chemical stability and does not mildew. However, like other polymer materials, aging will occur under direct sunlight, which makes the physical and mechanical properties of the material.

declines, but the rate of change is very slow, at 20 The thermal conductivity of polyurethane insulation board can be stable for 50 years.

Wide range of applications

Polyurethane insulation board is suitable for insulation projects of various industrial and civil buildings, and can be used for both new construction and old building restoration. The use temperature of polyurethane insulation board is -80 80, and it can be used in all regions of the country.

1. Expanded polystyrene board.

Expanded polystyrene board is a very widely used external wall insulation material at present, which occupies a very large proportion in the domestic and foreign markets. It has excellent thermal insulation performance and is a relatively mature thermal insulation product, but as a board, it has shortcomings such as low strength and poor fire performance. At the same time, it is necessary to wait for it to be fully matured before it can be posted during construction, otherwise it is easy to shrink and fall off.

2. Extruded polystyrene board.

Extruded polystyrene board, also known as XPS board, is a kind of insulation material commonly used by us in China. The board has excellent waterproof and thermal insulation properties, excellent strength and compressive properties, and low thermal conductivity, and is mainly used for roof insulation and building floor insulation.

3. Phenolic foam.

Phenolic foam is a new type of exterior wall insulation material, which will not burn in case of fire and will not emit toxic and harmful gases. It has the advantages of heat preservation and energy saving, non-toxic, non-corrosive, etc., with high cost performance and great development prospects. However, China's production technology is poor, the promotion is small, and there are relatively few people who choose the material in China.

In recent years, China's economic and social level has developed rapidly, and the urbanization process has a huge impact on the planning of urban internal construction. The exterior finishes of some old residential buildings in the city fall off and crack, which not only affects the appearance of the city, but also pollutes the urban environment.

According to the statistics of the Ministry of Housing and Urban-Rural Development, there are about 170,000 old communities in the country, with a construction area of about 4 billion square meters.

In the practice of old city renovation in China, three typical models have been formed: breaking the old and creating the new, coordinating planning, and reviving the old city. If you continue to use the traditional real stone paint to renovate, not to mention the need to renovate after many years, the pollution of paint and other materials to the urban environment should not be underestimated.

The shortcomings of traditional paint refurbishment construction, severe weather, slow completion speed, and short service life will make the renovation projects with long cycles, large dust, and affecting residents' lives even worse.

Shigongjiang thermal insulation and decorative integrated board is committed to making the city more beautiful and more convenient in construction, and actively develops thermal insulation integrated board technology to contribute to the city.

Conclusion: The market demand for the renovation of old residential areas is large, the urban development process is fast, and the traditional paint decoration is obviously not suitable, and the external wall insulation integrated board has been widely used.

The exterior wall insulation of this old community is made of insulation boards, because as long as the flame retardant insulation board is used, the fire prevention can be improved, so it is used as a thermal insulation measure.

①.Indoor water seepage caused by non-standard insulation construction: After adding insulation to the exterior wall of the old community, the biggest impact on residents is indoor water seepage.

The impact of the construction on the original water, electricity and gas: after adding insulation to the exterior wall of the old community, it is not only the construction of adding insulation layer to the façade.

There is no big impact. It is possible that during the construction process, the construction materials will occupy the area of the roadside, causing inconvenience for pedestrians. But these are temporary, and after the construction is completed, it can be restored.

It will have a certain impact on the building! It is still necessary to calculate according to the actual materials of the building, and the external wall insulation can make the building warmer and have the effect of cooling and insulation.

I personally feel good, after all, it will be a lot warmer, and the heating of the old community is certainly not very good, but the installation will definitely bring trouble to everyone.

The use of exterior wall insulation and decorative integrated board in the building exterior wall has become more and more common, especially in the cold cities in the north, the installation of external wall insulation and decorative integrated board is relatively early. What are the advantages of buildings that do not have thermal insulation and decorative integrated panels?

Next, I will take Jiunuo exterior wall insulation and decorative integrated board as an example to introduce the advantages of this new building material.

First, the well-known and most valuable advantage is that it can play the function of thermal insulation and heat conduction for the building, so that the building can achieve the effect of warm in winter and cool in summer. Due to the physical properties of the thermal insulation composite panel, the temperature can be retained in winter and the external temperature can be blocked in summer, so that the indoor temperature can be kept at a relatively stable level.

Second, because the external wall insulation material can protect the concrete and brick walls of the wall from external erosion and damage, the insulation decorative board can also extend the service life of the building. At the same time, because the exterior wall insulation and decorative integrated board can keep the indoor temperature stable, it can also protect the building wall from cracking and deformation.

Third, there are many varieties of exterior wall insulation materials, and the materials used for the interior are used, and the diversity of materials also has a good decorative effect on the building. Today's thermal insulation composite panels can imitate the appearance of stone, ceramic tiles and even metal, and play a later role in the decoration of the wall.

Fourth, the installation of insulation and decorative integrated board of the building, because the room temperature can reach a stable level. It can reduce the frequency of using air conditioners and other appliances, reducing energy waste and economic expenditure.

5. The exterior wall insulation board itself has the characteristics of light weight and no pollution, and is more convenient and environmentally friendly in the process of installation and use. And its.

With a high cost performance, when some buildings are renovated, the use of external wall insulation and decorative integrated board will also be very convenient and economical, which is the choice of many hotels and other enterprises when renovating buildings.
