Why do you need wall insulation materials for indoor partitions in high rise buildings?

The use of good insulation technology and materials in industry and construction can achieve twice the result with half the effort. For every ton of mineral wool insulation used in construction, one ton of oil can be saved a year. The insulation of industrial equipment and pipelines, using good thermal insulation measures and materials, can significantly reduce production energy consumption, improve the environment, and have good economic benefits.

Definitely. Otherwise, the building will fall.

1. Wide range of application.

External thermal insulation is suitable for heating and air conditioning of industrial and civil buildings, which can be used for new projects and old house renovation, and has a wide range of applications.

2. Protect the main structure and prolong the life of the building.

The wall insulation scheme is adopted, because the insulation layer is placed on the outside of the building envelope, the stress caused by the structural deformation caused by temperature change is buffered, the structural damage caused by rain, snow, freeze-thaw, dry and wet cycles is avoided, and the erosion of harmful gases and ultraviolet rays in the air on the enclosure structure is reduced. Facts have proved that as long as the wall and roof insulation materials are selected appropriately and the thickness is reasonable, the external thermal insulation can effectively prevent and reduce the temperature deformation of the wall and roof, and effectively eliminate the common oblique cracks or figure-eight cracks of the top horizontal wall. Therefore, the external thermal insulation can not only reduce the temperature stress of the enclosure structure, but also protect the main structure, thereby effectively improving the durability of the main structure, so it is more scientific and reasonable than the internal thermal insulation.

3. The influence of "thermal bridge" is basically eliminated.

The use of external insulation is more advantageous than internal insulation in avoiding "thermal bridges", such as "thermal bridges" generated at the junction of internal and external walls, external wall ring beams, structural columns, frame beams, columns, door and window openings, and the perimeter of the junction between the top parapet and the roof panel. According to statistics, the additional heat load of the "thermal bridge" in the ground floor room accounts for about the total heat load; Mezzanine rooms occupy ; The top floor room occupies . It can be seen that the impact of the "thermal bridge" is still large.

The above-mentioned "thermal bridge" is almost unavoidable for internal insulation and sandwich insulation, while external insulation can not only prevent condensation generated by the "thermal bridge" area, but also eliminate the additional heat loss caused by the "thermal bridge". The calculation shows that under the condition of 370mm thickness brick wall insulation, the peripheral "thermal bridge" increases the average heat transfer coefficient of the wall by about 10% compared with the heat transfer coefficient of the main part. In the case of a brick wall with a thickness of 240mm, the average heat transfer coefficient of the perimeter "thermal bridge" increases by about 51% to 59% compared to the heat transfer coefficient of the main part, while in the case of a brick wall with a thickness of 240mm, this effect is only 2% to 5%.

4. Improve the dampness of the wall.

Under normal circumstances, the internal insulation must be provided with a vapor insulation layer, and when the external insulation is adopted, because the main structural material with high steam permeability is located on the inner side of the insulation layer, the condensation analysis is carried out with the steady-state moisture transfer theory, as long as the insulation material is appropriately selected, the condensation phenomenon will generally not occur inside the wall, so there is no need to set up the vapor insulation layer. At the same time, because the temperature of the whole wall of the structural layer is increased after the external insulation measures are taken, and its moisture content is reduced, so the thermal insulation performance of the wall is further improved.

5. It is conducive to maintaining stable room temperature.

Because the structural layer with large heat storage capacity is on the inner side of the wall, when the indoor air temperature rises or falls due to the unstable heat action in the room, the wall structural layer can absorb or release heat, so it is conducive to maintaining a stable room temperature.

Aerogel insulation can be considered.

Aerogel is a new solid material with ultra-low density. With nanoporous structure and strong thermal insulation performance, it is a new green building material with wide application prospects.

In principle, the north winter time is long, building energy conservation to thermal insulation as the main goal, the vast majority of existing buildings at present, is to increase the thickness of insulation materials to meet the increasingly stringent energy-saving requirements, practice shows that the traditional insulation board not only has a limited energy-saving effect, but also has high material costs, construction difficulty, short life cycle, fire hazards are imminent, frequent accidents from high altitudes and construction waste is difficult to degrade and other serious problems, so that the whole city is full of danger. Therefore, for the northern region, a new type of insulation board can be used--- Zhongning Technology Aerogel Composite Non-combustible Insulation Board, which can solve the problem of easy falling off of rock wool board and the problem of non-flame retardant polystyrene board.

In the southern region, the summer time is long, and the main goal of building energy conservation is thermal insulation. At present, external wall insulation technologies such as EPS (XPS) thin plastering external thermal insulation system, rubber powder particle thermal insulation slurry external thermal insulation system, cement-based composite thermal insulation mortar external thermal insulation system by increasing thermal insulation materials may have a counterproductive effect. Therefore, it is suitable to use a thin-layer thermal insulation system with both thermal insulation and thermal insulation in the southern region - Zhongning Technology Aerogel Thermal Insulation Coating System, which has the advantages of integration of thermal insulation and decoration and simple construction, and can solve the problem of thermal insulation and thermal insulation.

Building insulation has gradually become a key topic in the field of construction. For a building, almost all parts are involved in the need for thermal insulation. Including the interior and exterior walls of the building, the roof, etc., only the overall thermal insulation can truly achieve the purpose of energy conservation and emission reduction.

Aerogel and its composite materials have different applications in different construction fields, which can play an effective energy-saving effect, which is also described in detail.

If the budget for exterior wall insulation is sufficient, and a high insulation coefficient is required, it is recommended to use aerogel insulation materials.

The construction industry is one of the fastest consuming industries in China, accounting for more than 30% of the country's total energy consumption. China's annual urban and rural construction area of nearly 2 billion square meters, of which more than 80% are high-energy buildings; The existing buildings are nearly 40 billion square meters, and more than 95% of them are high-energy buildings. At present, China's energy consumption per unit of construction area is more than 2 3 times that of developed countries, so the implementation of energy-saving and emission reduction policies is gradually increasing, and a number of building energy-saving standards have been proposed, aiming to promote and standardize the development of building energy-saving materials.

At present, there are many kinds of building thermal insulation materials on the market and are being studied, which can be divided into two categories in terms of material composition, one is inorganic thermal insulation materials, such as aerated concrete, glass fiber, rock wool, etc.; One is organic thermal insulation materials, such as extruded polystyrene board and polystyrene particles. However, at present, there are certain problems in the comprehensive thermal insulation effect of traditional thermal insulation materials.

The thermal insulation performance of exterior wall insulation is closely related to the material of exterior wall insulation. The lower the thermal conductivity, the better the thermal insulation.

Common exterior wall insulation materials are divided into inorganic and organic insulation materials.

XPS extruded board, EPS polystyrene board, PF phenolic board, PU rigid foam polyurethane board, RW rock wool, graphite polystyrene board, foam glass insulation board.

Exterior wall insulation materials refer to a type of insulation materials used for building walls, which can be divided into: exterior wall insulation materials, interior wall insulation materials, and roof insulation materials according to the use location; According to the intrinsic composition of insulation materials, it can be divided into: inorganic insulation materials and organic insulation materials.

Exterior wall insulation technology first originated in Europe, and China began to pilot in the mid-80s of the 20th century, and the technology was widely used in the field of construction. However, the current level of building energy conservation is still far lower than that of developed countries, and the energy consumption per unit area of buildings in China is still 3 5 times that of developed countries with similar climates.

Interior walls and exterior walls are OK, but there are more exterior walls.

To do interior wall insulation, it is better to use light steel keel as a skeleton, fill it with extruded plastic board, and then finish it with gypsum board. As long as the light steel keel, gypsum board, and extruded plastic board meet the standards.

These materials are sold in the building materials market, you can choose Lofeel light steel keel, Knauf gypsum board, and extruded plastic board 5 thick can meet the standard, and can ensure the service life.

In addition, a designer introduced two other methods, one is to extrude the plastic board and then hang the net in plastering, this method must be fully patched in the later stage, otherwise it will crack. The second is that extruded plastic board and cement pressure board are used for insulation of materials. But in general, it is recommended to use the first method introduced.

Is it on the inner wall? The net is inside the wall, so you shouldn't be able to see it after the renovation. I've seen that paving roads is covered with a net, which should make the structure between the walls stronger. It is purely an opinion of personal ignorance, and I don't know if it is correct or not.

Interior walls and exterior walls are OK, but there are more exterior walls.

From the fire to the air conditioner to the thermal insulation wall, people's lives are really progressing, air conditioning can no longer meet people's pursuit of life, after all, being under the air conditioning for a long time also has an adverse impact on our body, so people came up with the idea of making thermal insulation walls, so how to choose materials to make good thermal insulation walls? Here we will talk about the three characteristics of the required materials: good thermal conductivity, low material density, and material not easy to denature.

Good thermal conductivity requires it to absorb very little heat to ensure its basic function, if you don't know how to judge, you can read its manual carefully, find the thermal conductivity, generally when this value is lower than the specified value, its thermal conductivity is very good, made of thermal insulation wall is naturally good.

The small density of the material means that the internal material of the material is very sparse, and then it has the effect of heat insulation, which can store a large amount of heat and slowly release it into the air, bringing people a comfortable and warm space. The general materials are green and environmentally friendly materials.

Because the thermal insulation wall is composed of thermal insulation materials, if you want to keep the wall functional, you must ask for this thermal insulation material to be not easy to change, simply put, the characteristics of this material can not be easily lost, if you want to determine this, you can look at the specific composition of the material manual, understand its specific material, if the composition of the material is polymer, it means that its stability is relatively high, Then the thermal insulation wall made of it also has a long service life.

Good materials can make good thermal insulation walls, so you must not be careless when choosing thermal insulation materials, casually, and be careful and cautious.

Measurement and budgetingFirst vacate the room that needs to be insulated, measure the size of the wall, and convert the total area into the size of the insulation board, and get how many insulation boards are needed. Before construction, the wall needs to be cleaned up, if there is no wall skin detached, you can only clean the dust and floating dust, if there is a large piece of wall detached, you need to use a shovel to shovel down the wall skin, clean up and then construct. - For a flatter wall, you can choose nail-free glue, and extrude about 1 cm long gel at the four corners and middle positions of the back of the insulation board and stick it directly to the wall.

If you are or stupid to resist the uneven wall, you can use foam glue to squeeze it to the back of the insulation board, you can squeeze about three or four of it, and then stick it to the wall.

Wall insulation is very important, for every house, winter can block the cold outside, will not let the cold air outside so easy to come in; In summer, the indoor temperature will not be so hot, especially for the wall that will be exposed to the sun, and the wall insulation is more important, so that the indoor temperature will not rise too much because the sun continues to shine.

According to the position of insulation, it is mainly divided into external insulation, interlayer insulation and internal insulation. Among them, the most commonly used methods are internal insulation and external thermal insulation.

1. External thermal insulation is a method of using the insulation system to isolate the building by placing the thermal insulation system on the outside of the outer wall. As a rule, the insulation layer is fixed to the outside of the wall with adhesive, and the adhesive material is reinforced with fiberglass mesh or galvanized steel sheet on the outside of the insulation.

2. Internal insulation is a method of setting up a thermal insulation system inside the exterior wall to keep the building insulated. Typically, the inner surface of the exterior wall is applied with prepared insulation, smeared, spliced or directly with an insulating mortar layer for the purpose of wall insulation.

1. Internal insulation:

Advantages: simple structure, low cost, does not affect time.

Disadvantages: it will affect the decoration (after the decoration is completed, the insulation layer is inside, and the decoration of the wall will destroy the insulation layer), there will be condensation (because the wall is cold, the insulation layer is high, and the temperature difference between the inner layer and the outer layer is large), the insulation effect is not sufficient (because the insulation material will not block the thermal bridges that appear in the beams, columns and walls, resulting in poor thermal insulation and poor performance).

2. External insulation:

Advantages: The indoor space will not be occupied, and the effect of thermal insulation is better than that of internal thermal insulation.

Disadvantages: difficult construction (especially high-rise buildings), high cost, need for construction process, will drop the time and duration of the scaffolding, will have an impact on the exterior wall decoration (exterior wall tiles require very high technology).

This is all the introduction of wall insulation, you need to choose the use of internal insulation or external insulation according to the demand, can not choose blindly, otherwise it will have a bad impact on the decoration of the house.
