Building insulation board, insulation board has several materials

At present, the most energy-saving insulation materials used in China are polystyrene boards, part-molded polystyrene boards (commonly known as "polystyrene boards") and extruded polystyrene boards (commonly known as "extruded boards") and cement polystyrene boards.

Process to ferry** check "polystyrene board".

The production process includes external wall internal protection and external protection. The raw materials are generally vitrified microbeads...

220 yuan per cubic gray plate is the most common in general construction.

The raw material is also the worst, that is, some garbage**, and then processed to form particles, and then processed again, it is the so-called "polystyrene board", and the disadvantage is that the life span is generally about 2 years, the insulation coefficient is small, it is easy to decay, and the strength is low.

If you are a family, it is recommended to buy your own materials Generally, the pink and bright insulation board is unlikely to be made of poor raw materials, and the best board is elastic.

At present, the commonly used polystyrene particle insulation system achieves, and this thermal insulation performance is reached, but the process is complex, and the construction is difficult. The long-term insulation effect is not good, and the reason why there is a market is because it is cheap.

Secondly, the cost of stone curtain wall and glass curtain wall is too high.

Cost-effective insulation systemI personally think there are metal insulation systems and inorganic insulation systems. It can be used in dry hanging and wet pasting, and the whole factory is operational, easy to install, and has excellent performance.

If the aluminum-galvanized steel plate insulation system can be used outdoors for more than 50 years, it is difficult for other insulation systems to reach 20 years.

There are 4 types of insulation boards.

1. Extruded plastic board

The full name of extruded plastic board is extruded polystyrene foam board, also known as XPS board. It is a rigid foam board made of polystyrene resin as raw material plus other raw materials and polyinclusions, heated and mixed while injecting a catalyst, and then extruded and extruded.

Extruded plastic board has a perfect closed-cell honeycomb structure, with extremely low water absorption, low thermal conductivity, high compressive resistance, and aging resistance, and is a special material for floor heating insulation layer.

2. Polystyrene board

Polystyrene board is also known as foam board, polystyrene foam board, benzene board, referred to as EPS board. A white object made from expandable polystyrene beads containing a volatile liquid blowing agent, pre-formed by heating and then heated in a mold.

Polystyrene board has the structural characteristics of fine closed cell, and is widely used in construction, insulation, packaging, freezing, daily necessities, industrial casting and other fields. It is also used in the manufacture of exhibition halls, commodity cabinets, advertising signs and toys. It is also a common material for the insulation of interior and exterior walls of buildings, especially floor heating and insulation.

3. Polyurethane board

Polyurethane board is referred to as PU or PUR, which is a product of polyisocyanate and polyether or polyester polyol reflected in a certain ratio. Polyurethane panel refers to a polyurethane sandwich panel made entirely of PU or formed by the composite of PU and color steel plate.

4. Thermal insulation mortar

Polygranular thermal insulation mortar has the characteristics of simple and convenient construction, light weight, high strength, good thermal performance, low cost and good weather resistance. Vitrified microbead insulation mortar has excellent thermal insulation performance, fire and aging resistance, no hollowing cracking, high strength and convenient construction.

The material of the insulation board can be divided into expanded polystyrene board, extruded polystyrene board, phenolic insulation board and rock wool board.

Insulation board is a board with thermal insulation effect, generally used for wall decoration, using polystyrene resin, polyinclusion and other materials heated and mixed after injection of catalyst two production, has good moisture-proof, waterproof performance, and has excellent performance in fire resistance, heat preservation and strength.

Polyurethane insulation board has the effect of efficient thermal insulation, thermal insulation performance is better than mineral wool, glass fiber, polystyrene and other materials, and long service life, extruded thermal insulation is XPS thermal insulation board, the surface structure is dense, the inner layer is closed-cell structure, has good moisture resistance, even if used in a humid environment, its thermal insulation performance will not be affected.

Before doing thermal insulation construction, the wall should be checked to see if it is flat, and if there is a problem of unevenness, it should be treated accordingly immediately to ensure that the construction will not be affected later. Attention should be paid to the temperature of the construction site, and construction can only be carried out if the construction requirements are met. Once everything has been treated, it is time to protect the wall and extend its lifespan.

1. Extruded plastic board: This is a commonly used insulation board, with strong heat preservation, high pressure resistance, anti-aging, water absorption and other advantages.

2. Polystyrene board: also called foam board, polystyrene board is used as the insulation layer, which is often used as an external wall insulation board.

3. Polyurethane board: This kind of insulation board is mainly used in the field of air conditioning, cold storage and cold room, with good thermal insulation, waterproof and moisture-proof.

Hello dear to the insulation board is to use rock wool board. The raw material of rock wool board is rock wool, and the fire performance of rock wool board is much higher than that of ordinary insulation boards, and it is the highest fire performance among all insulation boards, so many places require the use of rock wool boards. When rock wool boards are generally used on exterior walls, they are basically rock wool boards with a thickness of 100mm to 130mm.

The installation of rock wool board is an external hot-dip galvanized welded wire mesh, which is fixed with plastic anchors, and the outer layer is smeared with building insulation mortar. Finally, a layer of plastering mortar is smeared, and then alkali-resistant glass fiber mesh cloth is added; Then apply a layer of plastering mortar to complete the construction of external thermal insulation.

There are many insulation board materials on the market in China, and different materials, their production processes and effects are different, so we should choose carefully and not be sloppy. So what are the insulation board materials? How much is the ** of the insulation board? Let's take a look!

1. Expanded polystyrene board: good thermal insulation effect, low cost, but poor strength, compressive and aging resistance.

2. Extruded polystyrene board: that is, XPS board, the thermal insulation effect, strength and moisture-proof effect are better than the former, but the price is relatively high.

3. Phenolic insulation board: Although the board is more expensive than the first two, it has better performance, thermal insulation effect and fire performance. However, it is brittle and easy to chalify, which will bring great inconvenience to the construction.

4. Rock wool board: its biggest advantage is that it has good fire resistance, is a class A non-combustible material, and has strong flame retardant ability. The disadvantage is that it is hygroscopic and does not have a good thermal insulation effect.

How much is the ** of the insulation board:

Article summary: Well, what are the materials of the insulation board and how much the relevant knowledge of the insulation board is introduced here, if you need to know more information, please continue to pay attention to Qeeka Home, and we will have better and more exciting content for you in the future.

Exterior wall insulation panels are mainly used to improve the thermal insulation performance of buildings and reduce energy consumption. The question of whether the exterior wall insulation board will absorb moisture mainly depends on the materials used and the quality of construction.

Under normal circumstances, the exterior wall insulation board will not absorb moisture under the correct construction and use conditions. Common exterior wall insulation board materials include polystyrene (EPS), extruded polystyrene (XPS), rock wool, polyurethane, etc. These materials are moisture-resistant and resistant to moisture penetration.

However, if there are loopholes or negligence in the construction of the exterior wall insulation board, it may lead to an increase in the contact area between the insulation board and the surrounding environment, which may cause moisture to penetrate into the insulation layer. In addition, if the construction of the waterproof layer is not mastered, it may also allow moisture to penetrate into the insulation layer, increasing the risk of moisture absorption.

Therefore, when installing exterior wall insulation boards, the following points need to be noted:

1.Choose high-quality exterior wall insulation board materials, with good moisture-proof performance;

2.Ensure that the construction process is strictly in accordance with the relevant specifications and construction technology, and do a good job in the construction of the waterproof layer;

3.Regularly inspect the building exterior wall insulation board system for damage or loopholes, and repair it in time.
