In recent years, fire accidents caused by high-rise building fires have occurred frequently, and the national building energy efficiency standard has gradually increased from 65% to 75%. It is an inevitable trend to use A-level fire-resistant insulation materials for exterior wall insulation materials. However, in addition to the excellent thermal insulation performance of A-level fireproof insulation boards and the advantages of A-level non combustible insulation boards, the following advantages of A-level fireproof insulation decorative integrated boards have also been recognized:

1. A-level fireproof insulation decorative integrated board has good stability.

Due to the similarity or similarity in chemical or physical methods such as bonding and mechanical bonding between the components of Class A fire-resistant insulation boards, even in harsh environments such as temperature changes, sunlight, rain, frost, cold, high temperatures, acidity, and alkalinity. Ensure the stability of the system. A-level fireproof insulation integrated board is a scientifically unique internal structure system that coordinates with the microscopic movement of buildings. The supporting materials, special-shaped parts, and supporting tools of the A-level fireproof insulation board system have been integrated with core technologies such as cavity free technology, breathing technology, and waterproofing technology in the entire system design, enabling the harmonious coexistence of the entire system and instrument system. Through systematic scientific internal adjustments, the lateral movement of the main building has been achieved.

2. A-level fireproof insulation integrated board has breathing function and no negative pressure.

The unique breathing technology of A-grade fireproof insulation board prevents the accumulation of internal moisture while eliminating negative pressure, preventing the disadvantages formed during the alternation of high and low temperatures, and avoiding the safety hazards of A-grade fires. A-level fireproof insulation board reduces construction difficulty and shortens construction period. The insulation effect of A-level fireproof insulation board is very good. In addition, the patented anchoring method, combined treatment, and cold bridge design can reduce energy consumption. Therefore, especially in harsh weather areas such as Northeast and Northwest China, the requirements for energy conservation and insulation are often high. Traditional insulation construction has brought great difficulties to construction.

The fully automated production, standardization, refinement of the dust-free workshop ensures that the entire production process is dust-free and avoids quality instability caused by discrete technology. The heat preservation and decoration integrated board is made of mixed slurry of inorganic heat preservation particles, aerogel, mineral fiber, plant fiber, inorganic cementitious material, cement, silica fume, etc. The high-efficiency insulation core material is combined with special technology to produce a first-class fireproof insulation board. The entire board is divided into A-side and B-side. During the construction process, A side is installed on the wall and B side faces outward.

This product combines A-grade fire-resistant inorganic insulation materials and high-efficiency insulation core materials, and combines various insulation materials into one. The advantages and disadvantages of various materials complement each other, resulting in stable and reliable product quality. All performance indicators have been tested and meet the standard requirements.
