The exterior insulation exterior finishing material of the exterior wall of high-rise buildings is generally selected: inorganic thermal insulation mortar is better. The reasons are:

1. High-rise buildings are decorated with mortar, which can avoid the possibility of falling after the block is decorated;

2. Reliable thermal insulation performance;

3. Cheap;

4. The color of decorative coatings is diverse, which can facilitate designers to express their design characteristics.

Article 2 of the "Interim Provisions on Fire Prevention of External Thermal Insulation Systems and Exterior Wall Decoration of Civil Buildings" stipulates that the external thermal insulation materials of civil buildings shall be materials with Class A combustion performance.

When designing exterior wall insulation materials, in addition to meeting the requirements of building energy conservation and the durability of the exterior wall insulation system, the purpose of use, location, construction method, performance of insulation materials, etc. should also be considered

Weather resistance. The quality of weather resistance determines whether the insulation system can maintain the long-term effectiveness of the main body of the building.

Thermal conductivity. Thermal conductivity is an important indicator to determine the thermal insulation performance of the board. The greater the thermal resistance of the plate, the more obvious the thermal insulation performance of the plate, and the greater the temperature difference between the two sides of the plate.

Tensile strength. After the plate products are put on the wall, they are directly faced with the gravity of the insulation board system itself and the external forces such as wind power, and reasonable process structure and supporting materials (such as various mortars and meshes) play a key role in solving the tensile capacity of the insulation board system.

Bulk density of the plate. The bulk density of the plate is an important index to determine the thermal conductivity, strength and dimensional stability of the plate.

Dimensional stability of the plate. After the insulation board is put on the wall, if the size of the board is unstable, the insulation board system will be more prone to cracking and deformation, leaving potential safety hazards.

Sheet water absorption. The water absorption of thermal insulation board products varies greatly due to the composition and internal structure of the material itself.

First, the status quo of building exterior wall insulation.

1.National Building Energy Efficiency Policy.

The national building energy conservation plan will save 30% of the comprehensive energy before 1995; 50% after 2005; 65% has been implemented since 2006, and 75% is currently being implemented on a pilot basis in municipalities directly under the central government;

2. The energy loss of Chinese buildings is 50% for walls, 10% for roofs, 25% for doors and windows, and 15% for basements and grounds. Nearly 2 billion new buildings are built in the country every year, and only nearly 5 billion energy-saving buildings have been achieved in the country, accounting for about 10% of the total number of buildings.

2. Exterior wall insulation materials.

2.Analysis of the advantages and disadvantages of various materials.

The biggest advantage of inorganic materials is that they have a high fire rating, which is a flame-retardant material, and the combustion performance can reach Class A;

The thermal conductivity of inorganic materials is greater than that of organic materials, and as external wall insulation, the thermal calculation of its insulation thickness is about 8-10 cm (cold areas in northwest China) and the wall safety is worth considering.

The biggest disadvantage of organic materials is that the fire rating cannot reach Class A in terms of the material itself, and the highest can reach Class B1 flame retardant, and can reach Composite Class A after modification.

The market recognizes that Du is better than HFS HF and other materials, you can learn about it.

1. Temperature environment.

It is best to choose insulation materials according to the local climate and temperature, such as the northern region, which is colder in winter, so it is necessary to choose some better insulation materials, benzene board is a good choice, and for the south where the temperature difference is not large, it is enough to choose vitrified microbead insulation mortar.

2. Thermal conductivity.

In the case of thermal insulation, it is recommended to choose a thermal insulation material with the minimum thermal conductivity, which is not only convenient for construction, but also takes up space.

3. Stability.

It is better to choose insulation materials with good chemical stability. At the same time, if it is an insulation material for the exterior wall, it is recommended to choose an insulation material with a low unit thermal resistance.

4. Mechanical strength.

Exterior wall insulation materials also need to have a certain load bearing capacity and be able to resist external collisions.

This is determined according to the local energy-saving requirements and the national building fire code GB50016, in the building insulation and exterior wall decoration there are regulations, the residence needs to use fire-resistant windows above 27 meters, so the cost is high, if you choose A-level fireproof, you don't need it, like the HF board on the market, HFS board and so on can reach A-level fireproof.

It's not much, based on experience, I will simply tell you the principle of ten ** choices! Hope it helps!

1. Preferential selection of insulation materials with low conductivity coefficient.

Under the condition of satisfying the thermal insulation effect, the thermal insulation material with the minimum thermal conductivity should be preferred, which not only meets the design requirements, is convenient for construction, reduces the cost of transportation, but also occupies less space.

2. The selected insulation material should have good chemical stability.

3. The selected insulation material has sufficient strength.

The insulation material should be able to withstand a certain load and resist the impact of external forces.

4. Insulation materials with reasonable cost performance should be selected.

5. Class A non-combustible insulation materials should be preferred.

In the building structure, the area with high fire protection requirements should be preferred Class A non-combustible insulation materials 6, and insulation materials with low water absorption or non-water absorption should be preferred.

The thermal conductivity of the insulation material will increase after absorbing water, so the insulation material with low water absorption or no water absorption should be selected to avoid the thermal insulation material absorbing water and increasing its thermal conductivity.

7. Low-density insulation materials should be preferred.

The low-density insulation material can reduce the load and facilitate the construction.

8. The selected insulation materials should have good workability and easy maintenance, and the insulation materials should have the characteristics of convenient construction, easy operation, easy to ensure quality, etc., and easy to maintain.

9. Insulation materials with a long service life should be selected.

With the extension of time, the physical properties of the insulation materials will inevitably decline, and the energy-saving effect will also be reduced, therefore, the thermal insulation materials with stable physical properties and good aging resistance should be selected to ensure the energy-saving effect and prolong the service life.

Based on experience, I will tell you this, you can see if it is suitable or not, and I hope it can help you.

When choosing materials for the insulation of the house, you need to pay attention to various matters. What materials are generally used for the insulation layer of the exterior wall of the house? PChouse will take you to find out.

The insulation material of the exterior wall of the house is as follows:

1. AEPS modified polystyrene board: a new type of insulation material, generally about three centimeters thick, the advantage is that the flame retardant reaches the A2 level, the insulation effect is good, and the disadvantage is that the cost is relatively high.

2. Polyurethane: a more commonly used insulation material in cold areas, with the advantage of good fire performance. Disadvantages: High cost of construction.

3. Foamed cement, etc.: as a thermal insulation material, it is relatively rarely used, and the advantage is that it is non-combustible, and the disadvantage is that it is fragile and the thermal insulation effect is average.

4. EPS polystyrene board: the most common thermal insulation decorative integrated board insulation material, the general thickness is greater than or equal to five centimeters, the advantage is that the cost is low, and the thermal insulation performance is also the best. The disadvantage is that the fire performance is up to class B1.

1. Expanded polystyrene board. This is the most common exterior wall insulation material at present, the proportion of the domestic market is very large, the thermal insulation effect is good, but its hardness is not high, the fire performance is very poor, the construction must ensure that it is thoroughly matured before it can be posted, otherwise there will be a shrinkage and fall off the problem.

2. Extruded polystyrene board. It can also be called XPS, is a common domestic insulation material, this kind of board has excellent waterproof and thermal insulation performance, good strength and compressive ability, and thermal conductivity is not high, is widely used in roof insulation and building floor grip insulation.

3. Phenolic foam. This is a new type of exterior wall insulation material, it will not burn in case of fire, there is no toxic gas, the texture is light, it can be insulated and energy-saving, it can resist corrosion, it is cost-effective, and the future is bright, but due to the limitations of production technology, the promotion is not large, so there are not many people who use it.

What is the difference between internal and external insulation of external walls? 1. There is a difference in location, the main place for the internal insulation of the external wall is the internal insulation layer, and the external insulation can be directly added to the external wall.

2. There is a difference in construction, the construction speed of the external wall insulation is relatively fast, while the external wall insulation is relatively long, and there is no way to construct it in rainy days.

The difference between external wall insulation and interior wall insulation 1. Different structural protection: The advantage of external wall insulation is that it is more conducive to protecting the main structure of the house and prolonging the life of the building. If the external insulation of the exterior wall becomes the internal insulation of the exterior wall, the load-bearing wall and parapet of the exterior wall will omit the insulation material, and the mortar thickness of the exterior wall will also become thinner.

2. The thermal insulation effect is different from that of Qingguo: the external thermal insulation structure of the external wall can promote the indoor temperature of the house to maintain a relatively constant temperature, which is conducive to improving the quality of the indoor thermal environment. The material requirements for external wall insulation are stricter and more demanding than those for external wall internal insulation.

The internal insulation of the external wall is prone to mold and other phenomena of the internal wall. The internal insulation structure will cause two temperature fields to appear on the internal and external walls, forming a temperature difference, which will cause instability to the building beam structure.

There are three types of exterior wall insulation materials, namely polystyrene board, insulation mortar, and phenolic foam. Polystyrene board is a wide range of exterior wall insulation materials. The insulation mortar is made of lightweight materials and has the advantages of good durability. Phenolic foam is the most promising insulation material for construction, which is light and non-toxic.

Polystyrene board, also known as EPS board, is a plate that is heated by heating the expandable polystyrene beads and forming them in a mold. Thermal insulation mortar is a ready-mixed dry mortar made of lightweight materials as aggregates and adding modified additives. Phenolic foam is a rigid foam plastic prepared with phenolic resin, smoke suppressant, curing agent and other additives.

This depends on the actual situation, mainly to see whether the exterior wall protective layer is still within the warranty period, if the exterior wall is still within the warranty period, then there is damage should be found to the contractor or to find the developer to repair, if the owner himself has no way to get in touch with the developer, then you can also find the property company of the community, let the property company negotiate on behalf of you. However, if the exterior wall has been out of the shelf life, then after the quality problem occurs at this time, the general developer will not bear the corresponding responsibility, let alone pay for the repair, in this case, you can choose to use public maintenance** to repair.

If the insulation layer of the exterior wall falls off, then the construction unit and the construction unit must be responsible, most of the insulation layer falls off is caused by quality problems, so the construction unit and the construction unit not only have to bear the responsibility for the void, but also have to pay for the loss. If the exterior wall of the general building is still within the warranty period, the construction unit and the construction unit need to compensate for the relevant losses, according to the relevant regulations, the minimum warranty period of the exterior wall decoration project is two years, and the specific warranty period depends on the provisions of the contract. During the warranty period, if there are problems such as water seepage on the wall, the construction unit should be responsible.
