Which construction method is the easiest and most effective for exterior wall insulation?

Exterior wall insulation board system and thin plastering system are two common exterior wall insulation material systems, which have certain advantages and characteristics in thermal insulation, heat insulation, waterproofing, fire prevention, etc. The following will introduce their differences and advantages and disadvantages from the following aspects.

First, the construction process.

Exterior wall insulation board system: the construction method of pasting the insulation board on the surface of the exterior wall, and then carrying out the construction method of mesh cloth and painting anti-cracking mortar, thermal insulation mortar, facing mortar and other processes;

Thin plastering system: directly on the surface of the exterior wall, first carry out the base treatment, lay the mesh cloth, and then carry out the finishing mortar plastering and other processes.

Summary: The construction process of the exterior wall insulation board system is more complex and requires a high level of technology and construction experience, while the construction of the thin plastering system is relatively simple.

Second, the thermal insulation effect.

Exterior wall insulation board system: It can effectively prevent indoor heat from being dissipated outward. The thickness is larger, which can achieve better thermal insulation effect.

Thin plastering system: The thermal insulation effect is relatively weak, and it is not suitable for use in cold areas.

3. Waterproof performance.

Exterior wall insulation board system: The insulation material used has good waterproof performance, and measures such as waterproof coating will be applied during the construction process, so as to effectively prevent rainwater from infiltrating into the wall.

Thin plastering system: It is necessary to add waterproofing agent to the finishing mortar, and at the same time, it is necessary to pay attention to ensure the flatness and compactness of the wall during construction to ensure the waterproof performance of the wall.

Fourth, fire performance.

Exterior wall insulation board system: The insulation materials used usually have a high fire rating, which can effectively prevent the occurrence and spread of fire.

Thin plastering system: It is necessary to add fire retardant and other measures during the construction process to improve its fire rating.

If you pay attention to the thermal insulation effect and fire performance, you can choose the exterior wall insulation board system; If you pay attention to ease of construction and cost control, you can choose a thin plastering system. The above is the discussion about exterior wall insulation board and thin plastering, welcome everyone to communicate in the comment area.

The most used are: expanded polystyrene board thin plastering system and extruded board thin plastering system, construction method:

Material preparation--- base wall treatment--- elastic line--- paste insulation board, and set up a wrapping net--- board seam treatment and board finishing--- insulation board grinding leveling--- anchor installation --- insulation board hidden inspection--- configuration of surface mortar--- lines and windows add plastic corner protection--- apply the first layer of plastering mortar--- laying glass fiber mesh (the first layer of reinforcement net) - apply the surface layer of plastering mortar--- the surface layer mortar hidden inspection and acceptance.

That's great, you can try it.

At present, the only system that can meet the requirements of fire protection and energy saving is the lamination system with screed, which can be laminated with polystyrene board or extruded plastic board. If the temperature difference is low, a single insulation material, such as inorganic insulation mortar, can be used. If the temperature difference is very large and the requirement of 65% is to be reached, a composite system is required.

The main forms of building exterior wall insulation are internal insulation, external insulation, mixed insulation, and self-insulation.

1. Internal insulation technology.

Exterior wall insulation technology refers to the use of prefabricated insulation materials on the inner surface of the exterior wall paste, splicing, plastering or directly as a thermal insulation mortar layer to achieve the purpose of thermal insulation.

2. External thermal insulation technology.

External wall insulation refers to the technology of thermal insulation on the outer surface of the external wall, which is usually composed of thermal insulation layer, protective layer and fixing materials (adhesives, anchors, etc.), because it can reduce the impact of thermal bridges and protect the external wall from excessive temperature deformation stress, which is the most widely used thermal insulation practice at present, and it is also the thermal insulation practice vigorously advocated by the state.

3. Mixed insulation technology inside and outside.

Mixed internal and external thermal insulation refers to the use of external thermal insulation in the parts that are convenient for external thermal insulation operation, and the internal thermal insulation in the parts that are inconvenient for external thermal insulation operation (note: the internal and external thermal insulation of mixed thermal insulation technology are complementary, not superimposed).

Fourth, self-insulation technology.

Exterior wall self-insulation refers to, the wall itself material has the function of energy saving and heat resistance, through the selection of appropriate insulation materials and the adjustment of wall thickness can achieve the purpose of energy saving and heat preservation, common self-insulation materials are: steam pressurized concrete, shale sintered hollow block, ceramsite self-insulation block, foam concrete block, light steel wire mesh frame polystyrene board, etc.

Summary. Hello, glad to answer for you;

1.External wall insulation is a construction method that places the thermal insulation system on the outside of the exterior wall to make the building achieve thermal insulation. Usually a layer of insulation material is fixed on the outside of the base wall with adhesive material, and the outer side of the insulation material is reinforced with glass fiber mesh or galvanized steel wire mesh and coated with adhesive glue, and the outermost layer is a facing layer.

2.Thermal insulation of the external wall is a construction method that places the thermal insulation system on the inside of the external wall to make the building achieve thermal insulation. It is usually on the inner surface of the exterior wall to use prefabricated insulation materials pasted, spliced, plastered or directly made insulation mortar layer to achieve the purpose of thermal insulation.

What are the insulation materials for celery finger walls? Six key points of construction.

Exterior wall insulation materials emerge in endlessly, and everyone is dazzled, so let's talk about it for you today, what are the common exterior wall insulation materials, and some construction points. Spine head cavity.

Common materials. Common exterior wall insulation materials include polystyrene foam board, extruded plastic board, rock wool board, polyurethane board, aluminum board, thin ceramic composite board, etc.

Construction points. 1.Choose the right material: choose the right exterior wall insulation material according to the wall structure, wall material, environment conditions and other factors.

2.Ensure that the base layer is dry and clean: before construction, it is necessary to ensure that the base layer of the wall is dry and clean, and remove oil and dust.

3.Ensure that the construction level is uniform: the material level should be uniform during construction to avoid omission or reapplication.

4.Ensure the quality of construction: Attention should be paid to quality control during construction to ensure that the adhesive of the insulation material is firm.

5.Avoid the phenomenon of thermal bridges: In the construction process, it is necessary to pay attention to avoid the occurrence of thermal bridges, especially in the parts of doors and windows, balconies, rainwater pipes, etc., and select appropriate thermal insulation materials for construction.

6.Ensure fire performance: Exterior wall insulation materials should have good fire performance to ensure the safety of the building.

If you want to decorate the dusty exterior wall, you must pay attention to related matters, such as construction methods, such as insulation materials, what are the external wall insulation materials? Today, I will answer them one by one for you.

First, the construction method of external wall insulation.

1. When the exterior wall is insulated, the fixed point between the wall and the base wall must be reliable, especially for high-rise buildings, so that the bearing capacity will be higher. Reliable and highly adhesive materials can be used to hold the two tightly together, especially for walls with insulation boards, this link must be paid special attention.

2. When the exterior wall is constructed with an insulation layer, it is necessary to pay attention to the fire performance of the system, and the dispersion must comply with the relevant laws and regulations of our country. There are many high-rise buildings that use flame-retardant polystyrene board, which is relatively flammable, so it is best to adopt relevant measures for fireproof construction, and there must be a fireproof isolation zone. The fire performance of organic insulation materials is very good, and it does not produce harmful gases.

3. The durability of the external wall insulation system must be good, generally speaking, its service life should be at least 25 years, so as to meet the use requirements. At present, the main material of the insulation system used in basic buildings is inorganic silicate material, because it has a very long service life.

2. What are the types of exterior wall insulation materials?

1. Thermal insulation mortar, it is a kind of ready-mixed dry mortar made by using various lightweight materials as aggregates, adding cement and cementitious materials, plus additives, and stirring, and its main role is to be used for external wall insulation.

2. XPS extruded polystyrene foam board also has a name called polystyrene extruded board, which has lower water absorption and thermal conductivity than other types of insulation materials, which is very corrosive, and has the effect of anti-aging, and has a wide range of applications, suitable for highway, airport, railway and other occasions for anti-freezing and thermal insulation.

3. Benzene board, there are many chances of using this material, but the thermal insulation effect is not too obvious, if you want to use this material, you also need to do a good job of waterproofing.

It can be seen that the external wall insulation decoration needs to pay attention to various problems, such as when the external wall is insulated, the fixed point between the wall and the base wall must be reliable, especially for high-rise buildings, so that the bearing capacity will be higher. At the same time, it is necessary to pay attention to the characteristics of external wall insulation materials to avoid wrong choices.

1. What is the construction method of external wall insulation?

First check the flatness of the substrate, if there is a bad phenomenon, it needs to be repaired and then leveled; secondly, measure the positioning with a spirit level, pop up the horizontal grid, and then pull out the vertical line; Then drill the hole according to the elastic line grid, and install the load-bearing parts; According to the ratio of 4 to 1, adjust the mortar and feed, and then fix the insulation board with a sticky anchor; Finally, wait 30 days and fill the caulk with sealant.

2. What are the precautions for the construction of external wall insulation?

1. The requirements of the base layer are relatively high, so it is necessary to check the flatness before construction, and carry out the leveling process according to the actual situation. Before installation, the exterior window should have been constructed and passed the relevant inspection, otherwise the external window will be unqualified and rectified in the later stage, which will affect the insulation wall that has been done.

2. There will be gaps in the connection between the wall and the frame, so the gaps should be filled in during operation to ensure compactness, so as to have a better thermal insulation effect. Of course, before carrying out the relevant operation, it is necessary to protect the doors, windows or other outer edges to avoid increasing the difficulty of cleaning later.

3. There are also requirements for the weather of construction, the temperature should not be below 5 degrees Celsius, the wind force should not exceed level 5, and the construction can not be carried out in rainy and snowy days, because this weather will affect the performance of thermal insulation. Whether the effect of thermal insulation is good or not, most of it depends on the base layer, so before this operation, it is necessary to accept the base layer, and then carry out the operation of external wall insulation after passing the acceptance.

Summary: What is the construction method of external wall insulation and the construction precautions of external wall insulation are introduced here, I hope that the above content can let you know more about the relevant knowledge of external wall insulation. If you need to know more about it, please continue to ******, and more exciting content will be presented to you in the future.

In the cold winter, many home decoration will do wall insulation construction, to maintain the indoor temperature of the house, so that we are more comfortable and warm, and now people also have a certain waterproof effect on the wall insulation construction materials, which are also widely used in the housing construction industry, and the method of wall insulation construction basically has four processes, namely: the cleaning of wall debris, the measurement of the insulation board, the paste and grinding of the insulation board.

In the construction of wall rubber and external thermal insulation, first of all, we have to clean up the debris on the wall, clean the wall, maintain a certain degree of cleanliness, and still use cement ash to repair it in some places on the wall.

It is also necessary to measure accurately, especially in the position of the door, to prevent the inclination of the insulation board in the back construction.

If the external wall insulation work is only limited to pasting the insulation board, then its adhesion to the wall is not strong enough. If the insulation board is firmly attached to the wall and will not fall easily, it is also necessary to double strengthen the machine. In the construction process of external wall insulation, you can use an electric hammer to chisel a few holes in the insulation board, and then nail them, so that the firmness is very sufficient.

Finally, it is the most important and the last step in the external insulation construction of the trace, after all the insulation boards are installed, it is necessary to ensure that the surface layer is smooth and free of impurities, otherwise it will be very difficult to wipe the wall in the future, and the effect is greatly reduced. If the gap between the board is relatively large after the insulation board is installed, it must be filled to keep the wall not too large.

The above is the simple four steps of the external wall insulation construction, do not underestimate the role of the insulation board, if the paste process is done in place, then its role will not be underestimated, not only heat insulation, heat preservation, but also for the protection of the wall is also very obvious.
