What is the practice of building wall insulation

In the northern region.

The walls of the building will have a layer of insulation. So, what is the practice of building wall insulation? Specifically, it needs to go through four steps: base surface treatment, adhesive insulation board, glass fiber mesh, and finishing coating.

The first step in the practice of building wall insulation is the base surface treatment. The treatment of the base surface of the wall is very important, which is directly related to whether the insulation layer can be pasted firmly. The standard of base surface treatment is to use grinding tools to polish and clean the wall, remove cement residue and excess building materials on the wall, and make the wall clean and flat.

For the wall construction left by the rod hole, it should be tightly sealed. After the base surface is treated, an even layer of interface agent should be applied to the wall.

The second step of the building wall insulation layer practice is to glue the insulation board. Before sticking the insulation board, it is necessary to pre-typeset according to the size of the wall, and use elastic lines to draw a specific paste outline on the wall to facilitate the actual paste operation. When pasting the insulation board, it is recommended that two staff members cooperate to operate, one person is responsible for smearing glue on the insulation board, and the other person is responsible for pasting the insulation board.

The third step of the building wall insulation layer practice is to lay the fiberglass mesh. Wait for the insulation board to be pasted for one day.

It's time to lay the fiberglass mesh. The purpose of laying fiberglass mesh is to strengthen the insulation layer and prevent the insulation board from falling off. Before laying, a percussion drill is used.

Drill holes to install anchors on the pasted insulation board, and after installing the anchors, the glass fiber mesh coated with adhesive is smoothly pasted onto the insulation board.

The fourth step in the practice of building wall insulation is the finishing coating. After all the above operations are completed, the wall finish is also coated. Because only the installation of insulation layer on the wall will particularly affect the appearance, so a layer of decorative paint should be applied to the outside of the insulation layer.

The practice of building wall insulation layer is not difficult, but the workload is relatively large, and it is necessary to pay attention to the division of labor and cooperation in actual operation in order to complete the project efficiently.

Exterior wall insulation is one of the important measures to improve building energy efficiency and maintain indoor comfort. According to the relevant standard requirements of the People's Republic of China and the actual situation, external wall insulation mainly includes the following layers.

The first is the base layer. The base treatment is to enhance the adhesion between the insulation material and the wall and prevent the cracking and falling off of the insulation layer. Common base treatment methods include cleaning the wall surface, repairing the wall surface damage, brushing waterproof coatings, etc.

This is followed by the insulation material layer. The insulation material layer is the key layer that plays the role of thermal insulation. Depending on the building design and regional climatic conditions, different types of insulation materials can be selected, such as extruded polystyrene (XPS), expanded polystyrene (EPS), rock wool, glass wool, etc.

The thickness of the insulation material layer is determined according to the insulation requirements of the building.

The third is the protective layer. The main purpose of the protective layer is to protect the insulation material from the external environment and increase the durability of the building. Common protective layer materials include exterior wall paints, latex paints, veneer tiles, etc.

The choice of protective layer needs to consider factors such as architectural style, decorative effect and durability.

Finally, there is the decorative layer. The decorative layer is mainly used to beautify the appearance of the building and increase the visual effect of the building. The decorative layer includes exterior wall paint, stone, color steel plate, curtain wall, etc. The choice of decorative layer should be made based on factors such as design requirements, building type and budget.

In short, the level of external wall insulation mainly includes the base treatment layer, the insulation material layer, the protective layer and the decorative layer. Each floor serves an important function, thus achieving the goals of insulation, energy efficiency and aesthetics of the building. During the construction process, the operation should be carried out in strict accordance with the relevant standards and requirements to ensure the quality and use of the project.

The insulation layer of the building wall is divided into the following steps.

1. Grassroots treatment.

2. Elastic line typesetting preparation for construction.

3. Adhesive boards, walls and boards are plastered with cement.

4. Anchor fixing.

5. Thermal insulation caulking strip caulking.

6. Paste masking paper.

6. Silicone glue and weather-resistant glue sealing.

7. Tear off the masking paper.

The insulation layer is a professional structural layer, which is made of insulation materials, and its main role is to improve the performance of house insulation and insulation.

When the insulation layer is a part of the building wall, it is more than the wall is glued together, divided into two kinds of exterior wall insulation layer and interior wall insulation layer, the interior wall insulation layer is relatively thin, and the exterior wall insulation layer must reach a certain thickness in accordance with the relevant regulations to be qualified, it is composed of high-quality insulation materials, plays an important role in thermal insulation, is a professional structural layer.

First, what is the insulation layer?

The insulation layer is the specialty of the building, the structural layer is composed of advanced insulation materials, it will be pasted on the surface of the exterior wall or the surface of the interior wall, its specific thickness is not fixed, users need to determine the thickness of the insulation layer according to their own needs and related conditions, as well as the temperature of the environment. Although it is divided into two types: interior wall insulation and exterior wall insulation, if you choose interior wall insulation, it will reduce the usable area of the interior, so most buildings now choose to add insulation layer at the outer layer.

Second, what are the materials of the insulation layer?

Now the insulation layer is mostly made of foam board, they are better functional insulation materials, especially polystyrene foam board and polyurethane foam have good thermal insulation performance, with them to make the insulation layer can improve the thermal insulation ability of the house, will make the indoor environment more comfortable and can also reduce the energy consumption of the house. The insulation layer made of polystyrene foam board is more powerful, it can not only insulate and keep warm, but also has good impact resistance, and it is not easy to deform and fall off during use, and has a long service life.

Third, the role of the insulation layer

The insulation layer has a good protective effect on the main structure of the building, it is mostly pasted on the wall of the exterior wall is a very important part of the building structure, the insulation layer has a good thermal insulation effect, it can avoid climate change in the external environment, has too much impact on the indoor temperature, can buffer the temperature change, resulting in structural deformation, can also prolong the service life of the building, improve the durability of the main structure. The insulation layer can not only make the indoor environment more comfortable, but also reduce the damage of wind and moisture, which will keep the room in a relatively dry state, which can prevent mildew in the room.

The insulation layer is a special structural layer in the building, which is made of insulation materials and plays the role of heat preservation and cold protection. Some people don't like this kind of insulation and feel that it affects the decoration effect.

That is, when the wall is decorated, the main role of a structural layer is to play a thermal insulation effect, and it is also for thermal insulation, which can better protect the wall.

It is a professional term for decoration, which refers to the process of decoration, which will add some things that can be insulated to the wall structure or roof, so that it is not particularly cold in winter, and can also achieve rain prevention and warmth, and can also achieve the effect of warm in winter and cool in summer.

The insulation layer can be better insulated, which can make the temperature in the house higher, can avoid the temperature in the house from dissipating, so that people have a good living environment, and the temperature in the house is suitable for people's lives.

When building a house, you need to pay attention to building walls and insulation. How is the wall insulation layer constructed? PChouse will take you to find out.

1. Grassroots cleanup.

First of all, clean up the residual ash on the concrete wall to see if there are any debris such as release agent oil stains, and repair if there is plastering hollow parts. Fill all kinds of openings tightly. The deviation of the surface smoothness key is less than 4 mm, and when the deviation is exceeded, the protruding wall is polished, and the recessed part is repaired.

2. Wall measurement, elastic line, hanging line.

According to the design requirements of the building façade, the external doors and windows, vertical control lines and telescopic lines should be marked on the wall. Hang vertical datums at the large corners of the building exterior wall to control the verticality and flatness of the polystyrene panels.

3. Paste the wrapping mesh cloth.

In the exposed part of the side of the polystyrene board, it is best to do the mesh cloth turning package treatment first. The 80 mm width of the mesh cloth about 200 mm wide is pasted on the base surface with mortar, and the remaining mold bright source mesh cloth is turned over later.

4. Prepare special binders.

This step is very important if you want to do a good job of insulation. During the preparation process, you should stir while adding water, and then use a handheld electric mixer to stir, about five minutes, if the stirring is uneven, you can add time until the consistency is moderate.

5. Pave the mesh cloth.

Tighten the mesh cloth and stick it to the bottom layer, and then press it into the mortar to get the surface layer, remember to flatten it, and it is strictly forbidden to wrinkle the mesh cloth. When there is a lap joint, first meet the lap length requirements of 100mm transversely and 75mm longitudinally. The surface mortar should not be rubbed constantly to avoid the formation of hollow drums.

The insulation layer of the house plays a very important role in the suspicious seller's ambush, which can prevent water seepage. How does the insulation layer of the interior wall of the house be done? PChouse will take you to find out.

1. Before construction, the wall needs to be cleaned up, if there is no wall skin detached, you can only clean up the floating dust, if there is a large piece of wall detached, you need to use a shovel to shovel the wall skin down, clean up and then construct.

2. In order to prevent the insulation board from being crooked before construction, you can first use an ink fountain to draw a baseline on the wall or point out traces to ensure that the entire insulation board will not be crooked during the construction process.

3. You can also paste the insulation board, one is a relatively flat wall, you can choose nail-free glue, and extrude about 1 cm long gel at the four corners and middle positions on the back of the insulation board, and stick it directly to the wall. One is the uneven wall, which can be squeezed to the back of the insulation board with foam glue, about three or four, and then glued to the wall.

When the house is decorated, people will also do insulation on the inside of the wall, which can keep us from hot in summer and not cold in winter. It has a comfortable feeling. So this decoration is also indispensable.

So,wall insulationHow to do construction? It is a problem that needs to be understood when decorating. Let's introduce you to the knowledge of wall insulation.

Let's find out.

First, how to do the construction of wall insulation layer.

1. The insulation of the main material is selected as the insulation material is like choosing the right clothes for the house. In addition to its beautiful appearance, what is more important is its performance. When choosing a thermal insulation board, please choose a thermal insulation board with good performance, environmental protection, harmless to the human body, no harmful gases, and consider its best thermal insulation board.

There are many types of interior wall insulation materials on the market.

2. According to the construction method, there are: smeared insulating coating, and self-adhesive insulating board. Paint coating is very simple, everyone knows, here is the main introduction of the construction method of adhesive insulation board.

In addition to the insulating board, the choice of excipients also requires the use of special glue to fix the insulating board to the wall. There are two kinds of glue recommended here, one is environmentally friendly glue-free, and the other is foam glue extrusion. If the wall is relatively flat and there is no wall peeling, nailless adhesive can be used; If you want to remove the walls, you can choose foam glue.

3. Measurement and BudgetFirst of all, vacate the room that needs the separation wall, and measure the size on the wall. The total area is converted to the size of the insulating board, and how many insulating boards are needed. Note: You need to prepare some insulating boards when cutting for waste.

4. Wall waterproof measures before construction: If the wall is damp, peeling and mildew, it is best to make the wall waterproof and moisture-proof before pasting the insulation board, so as to avoid the completion of the moldy wall insulation layer after moisture-proofing. Currently, there are many waterproof and moisture-resistant materials.

The simplest and most convenient is the waterproof coating. It can be dried after painting. If the wall is very dry, you can skip this step.

Second, what are the functions of the insulation layer?

1. Some people don't understand the role of external wall insulation, and it doesn't matter whether they do it or not. This is a big misunderstanding. The exterior wall insulation is very good. One of the most important aspects of this is the protection of the main structure, as the insulation is located on the outside of the building envelope.

2. The outdoor climatic conditions lead to a large change in the internal temperature of the wall, which occurs in the outer insulation layer, buffers the stress caused by the structural change caused by the temperature change, prevents the temperature change of the internal main structure, effectively improves the durability of the main structure, and establishes life extension.

3. The temperature is too high in summer and too cold in winter, which makes people very uncomfortable, so many owners will isolate the exterior wall. Exterior wall insulation not only improves the indoor environment, but also has a thermal insulation effect. Not only does this greatly reduce damage caused by wind and rain, but it also increases indoor dryness and avoids indoor mildew.

This is also in line with our better use of the wall and gives us a better decoration of the wall.

How to do the construction of the wall insulation layer and what are the functions of the insulation layer are introduced to you, so that after we have a clear understanding, it is also when decorating, there is a better effect.
