YT inorganic active wall insulation system
YT inorganic active wall insulation system is a new type of netless insulation system developed by Nanyang Yintong. This material adopts a unique process and the bonding strength can reach 0.6MPa. Therefore, even the veneer brick can be directly insulated. The material is pasted on the outside, and no mesh cloth or rivets are needed. It does not need anti-cracking mortar and plastering mortar. It also has many advantages such as water resistance, crack resistance, anti-air drum, Class A non-combustible, etc. The remarkable advantages of this material are It will certainly occupy a large share of the insulation sector in the future.

Cement foam board
Cement board foaming is made of cement as the main raw material, combined with a unique formula. The fire rating is Class A. Eight Baidu's high temperature baking for three hours can still maintain the integrity. It can be effectively used on the outer wall. The fire performance of the building, the closed cell ratio is more than 90%, has good thermal insulation performance, and the construction process is relatively easy. It will not burn under high temperature and no toxic chlorine is released. It is both fireproof and heatproof. It is safe. Environmentally friendly materials.
Rock wool mineral wool board
The rock wool is mainly used as the outer wall thermal insulation material and the concrete is cast once or the steel mesh mechanical anchor is used for anchoring the rock wool board. Although the rock wool mineral wool board is made of inorganic materials, it can be used to press the organic rubber to form the board. It can not avoid the possibility of aging degumming, and it has the disadvantages of water absorption, low tensile strength and environmental protection for the construction workers. The use of rock wool for building insulation is not a problem. The key point is that the quality of rock wool used for building insulation cannot meet the needs of building applications.
Foamed phenolic board
The foamed phenolic board can only reach the B1 level. It has the disadvantages of large rigidity, easy to break, not easy to nail, not easy to punch, easy to absorb moisture, easy to powder, expensive, construction adhesive is organic material, and the joint strength is low.
Foamed glass board, foamed ceramic board
Foamed glass plate and foamed ceramic plate belong to the same high-temperature sintering material, the production energy consumption is too high, and the clay resources are limited, the closed cell ratio of the foamed glass is low, the thermal conductivity of the foamed ceramic plate is too high, and the material is bonded to the base wall material. The differences and other issues have restricted the promotion and application of such exterior wall insulation materials.
Hard foam polyurethane external insulation system
The polyurethane insulation material is sprayed on the base wall by a polyurethane foaming process, the polyurethane material surface layer is leveled with a leveling material, and the finish layer can be decorated with a paint or a tile. Features: good insulation effect, can achieve energy saving of 65%, and construction speed is fast, can significantly shorten the construction period
Insulation block and prefabricated insulation board external insulation system
The thermal insulation block is prefabricated with lightweight mortar or the prefabricated insulation hanging plate of the factory is combined with the wall to form an insulation system. Specific: The construction speed is fast, and the construction period can be significantly shortened.
XPS off-board insulation system
Replace the insulation system formed by the XPS board with an XPS board. Features: low thermal conductivity, good thermal insulation properties, but the XPS board adhesion and permeability need to be studied.
The above are some of the common aspects of the external insulation system. After reading these, everyone should understand what the external wall insulation materials are for your reference.
