In the future exterior wall insulation market, the state will launch that material of exterior wall

EPS (Molded Polystyrene Foam) boards or pellets. In addition, rock wool, expanded perlite, aerated concrete, etc. are also optional insulation materials.

Exterior wall insulation material A1 non-combustible A1 fire retardant Nanyang JETCO.

B1 polystyrene insulation board is not good.

Rock wool is now a good external wall insulation material, and it is a grade A insulation material. It has a very mature application abroad. Many people are prejudiced against rock wool, because there was no rock wool in China before, and mineral wool was regarded as rock wool.

Leads to people's thinking that rock wool is not good. The true hydrophobicity of rock wool can be achieved. And the service life can reach the same life as the building.

It can be said to be a cheap and beautiful A-grade insulation material for exterior walls. Our company specializes in the production of this kind of rock wool. At present, all the parameters of the "Kaihua" brand rock wool produced by our company have reached the international first-class level.

Class A exterior wall insulation material currently on the market.

1. Classification of non-combustible insulation materials for external thermal insulation systems.

At present, there are four types of non-combustible insulation materials used in external thermal insulation systems: foamed ceramic insulation board, composite cement foam insulation board, aerated concrete board, and rock wool board (strip).

1. "GZ" inorganic active wall insulation and anti-crack material

2. Foamed ceramic insulation board.

The foamed ceramic insulation board prepared by inorganic ceramic materials through high temperature roasting is referred to as ceramic insulation board.

3. Composite cement foam insulation board.

It is a closed-cell lightweight water-repellent insulation board made of cement, fly ash, silica fume, etc., through foaming, curing, cutting and processing processes.

4. Aerated concrete slab.

Lightweight concrete slabs are made of raw materials such as lightweight materials, siliceous materials and gassing agents, and are autoclaved by a certain production process.

5. Rock wool board.

It is a plate made of natural igneous rock, etc., which is melted at high temperature and made by centrifugal method, and is made of thermosetting resin as a binder.

The national policy on external wall insulation materials mainly includes Document No. 46 of the Ministry of Public Security and Document No. 65 of the Ministry of Public Security.

Langfang, Hebei Province is a base for the production of insulation materials, and you can look up again. A lot.

**Due to the differences in product materials, processes, etc., there is not much difference between the construction method and the usual construction.

There are 4 types of new exterior wall insulation materials, including:

1. Aluminum silicate insulation material, which is a new type of wall insulation material, is mainly made of natural fiber and auxiliary materials.

2. The phenol first grasp aldehyde foam material is mainly made of phenolic resin foaming, which has the characteristics of light weight.

3. Extruded plastic board, which is a material that is continuously extruded into foaming and forming by a special process, has the characteristics of light weight and heat insulation.

4. Foam board, which is made of expandable polystyrene beads, has a wide range of applications.

The role of exterior wall insulation materials 1, the degree of exterior wall insulation materials has a certain protective effect on the exterior wall body, which can not only protect the temperature difference of the exterior wall body from changing greatly, but also increase the durability of the exterior wall building and improve the service life.

2. Exterior wall insulation materials not only have the effect of thermal insulation indoors, but also improve the indoor environment, so that the indoor will not be damp and mildew, so that we can have a dry indoor environment.

3. We install exterior wall insulation materials on the exterior walls, which is not only a low-carbon and environmentally friendly decoration method, but also can effectively avoid the invasion of cold air on the house, which greatly prolongs the life of the house.

Exterior wall insulation construction process 1Construction technology: base treatment, configuration of building adhesive, pasting rock wool board, installation of fixings, plastering mortar, alkali-resistant grid cloth, plastering mortar, thermal insulation system acceptance.

2.Hang the baseline: hang the vertical baseline at the big corner (yin and yang angle) of the outer wall of the building and other necessary places, and hang the horizontal line at the appropriate position of each floor to control the verticality and flatness of the rock wool board.

3.The rock wool board should be paved horizontally along the horizontal direction from bottom to top, and the adhesive mortar (not less than 60%) has been plastered; The side wall rock wool board should be staggered and locked. The vertical seam should be staggered according to the row of seams 1 2 plate length or 200. Often, use 2

m Ruler and template check the straightness, if it does not meet the requirements, please correct it in time. Remove the adhesive that spills on the edge of the board in a timely manner, and the surface of the board shall not be coated or stained with adhesive. Foaming agent tamponade with large voids.

4.Install anchors: Install anchors after the primary mesh cloth (allowed joints) is hung and solidified, and the anchors should be installed 25 cm deep into the wall, and the anchors should be evenly arranged. The sunny angle of the outer wall should be encrypted, and the distance from the sunny angle should be 100-200

mm plus anchors.

5.Plastering layer construction: After the anchor is installed, the second mesh cloth is carried out, the mesh cloth is lapped with 100-150 MPa, and the verticality and flatness are checked in time after the construction of the plastering layer is completed, and the patch is repaired in time if it does not meet the requirements.

Rock wool board. The thermal conductivity is a kind of mineral fiber made of basalt and other natural ores as the main raw materials, melted at high temperature and centrifugal injection, pressed and cut after mixing a certain proportion of binders and additives. It is characterized by Class A fireproof, good sound insulation performance, high temperature resistance, and suitable for harsh environments.

Glass wool board. The thermal conductivity is that it is a material that is melted at high temperature using quartz sand, limestone, dolomite and other materials, glass fibrosis and heated molten solid resin to form a cotton-like material, which is characterized by no strength of the material, simple construction, and is generally used for the insulation of curtain wall systems and pipelines with low fire protection requirements.

Rigid foam polyurethane.

The thermal conductivity is divided into on-site foamed polyurethane and factory-prefabricated rigid foam polyurethane sheets according to the process. It is characterized by good waterproofness, good bonding performance, and convenient construction and operation.

Extruded polystyrene board.

Thermal conductivity, with polystyrene resin or its copolymer as the main component, adding a small amount of additives, through heating extrusion molding and the preparation of rigid foam products with closed-cell structure, characterized by high strength, moisture resistance.

Expanded polystyrene board.

The thermal conductivity is a polystyrene foam sheet with a closed-cell structure prepared by heating and pre-foaming the expandable polystyrene beads and then heating and forming them in a mold. It is characterized by mature technology, cheap and convenient construction.

Benzene board, benzene board is now used more, but its thermal insulation effect is not ideal, it will absorb water, so the use of benzene board will generally do some waterproof measures. Second: extruded board, extruded board is much better than benzene board, thermal conductivity is lower than benzene board, slightly higher.

Third: polyurethane is a relatively high-end insulation material, but also the best performance, generally used in some places with extremely strict requirements in this regard, and because it is high, there are fewer residential buildings. Fourth:

Glass wool and rock wool, glass wool and rock wool have many similarities in performance, and many people are easily confused, but because glass wool feels better than rock wool, it is generally higher than rock wool. Hope mine is helpful to you.

Answer]: A Commonly used external insulation materials for external wall insulation are: expanded polystyrene board (EPS), extruded polystyrene board (xps), rock wool board, glass wool felt and ultra-light thermal insulation slurry.

The commonly used macro cavity insulation board for external wall insulation includes GRC internal insulation board, glass fiber upscale Qiqiang gypsum external wall insulation board, P-GRC external wall internal insulation board, etc.

The other is the integration of building structure insulation materials (CL system, FS board, OKS, CT, etc.) insulation integration with self-insulation block construction, basically insulation particles and lightweight mortar leveling, the thickness is generally not more than 20mm thick. There is also a kind of green building exterior wall panel with integrated thermal insulation, finishing, and photovoltaic power generation. Exterior paints.

Exterior wall coating is to decorate and protect the exterior wall of the building, so that the appearance of the building is beautiful and tidy, so as to achieve the purpose of beautifying the urban environment. At the same time, exterior wall coatings can also play a role in protecting the exterior walls of buildings and prolonging their service life.

Overall thermal insulation materials: vermiculite concrete, expanded perlite concrete, fly ash ceramic concrete, clay ceramsite concrete, pumice concrete, slag concrete, etc., with some properties of loose materials, good integrity, convenient construction; The new thermal insulation and decoration integrated board is produced through the assembly line, integrating insulation, waterproofing, finishing and other functions, which is the preferred material to meet the current energy-saving needs of housing buildings, improve the insulation level of external walls of industrial and civil buildings, and is also the preferred material for energy-saving renovation of existing buildings.

If it is foam, it should be EPS insulation board, there are several fire grade EPS insulation boards on the market, if this kind of board is used for exterior wall insulation, you should choose products that meet the national requirements of fire rating. The scope of application of this regulation: the construction and acceptance of the external thermal insulation system of industrial and civil buildings with polystyrene board as the insulation material, polymer adhesive mortar as the adhesive material, polymer plastering mortar as the plastering layer, and alkali-resistant glass fiber plastic-coated mesh cloth as the reinforcing material and supplemented by clamping nails for anchoring.

EPS polystyrene board: the most common 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.

AEPS modified polystyrene board: a new type of insulation material, generally about three centimeters thick, advantages: flame retardant up to A2 level, good thermal insulation effect, disadvantage is that the cost is relatively high.

It is not high, because the difference in material also determines the difference in **, you can choose foam glass plate, ** in about 35 yuan.

I think the material of the exterior wall insulation decoration is very high, and their material is also very good, and it is also very good to use.

I think it's still very high, and the construction is difficult and easy to be dangerous, so the cost is very large.

In fact, I think these prices are generally not too high, because the materials for thermal insulation and decoration require a certain amount of technology. And it makes sense that the price is a little higher.

I think it's still relatively high, and there will be different pricing depending on the quality and durability.

In fact, ** is not particularly high, within the range that everyone can accept, so you can also choose.

It still depends on the area used, if it is only used in the building, it is still very preferential, if it is used in a square area, it is a little expensive.
