Good workability

Du Run fire insulation board is a cement-based porous material, homogeneous with mortar and wall, excellent interface, simple cleaning can be directly pasted, and the viscosity is firm.

Good sound insulation

The inner structure of the fireproof material contains a large number of independent air bubbles, and the sound insulation effect reaches 60db (140mm).

Compression resistance

The company has inspected the finished materials many times. After freeze-thaw experiments, the quality loss rate is <5% and the strength loss rate is <20%, and the performance is still stable.

Low water absorption

Durun fireproof thermal insulation panels have low water absorption, will not mildew in humid environments, will not affect thermal insulation performance, and ensure product safety and durability.

High thermal insulation

The closed cell rate of thermal insulation panels is >95%, and the lowest thermal conductivity can reach 0.045W/M.k, can meet the needs of building thermal insulation.

Antifreeze

The company has inspected the finished materials many times. After freeze-thaw experiments, the quality loss rate is <5% and the strength loss rate is <20%, and the performance is still stable.

Low cost

The cost is low, the life span can reach more than 50 years, and the exterior wall insulation construction can be repeated many times during the use period.

Fireproof

The fire-resistant temperature can reach more than 1000, and the fire-resistant safety performance is superior, and it will not pulverize after excessive fire.

Green environmental

The company has inspected the finished materials many times. After freeze-thaw experiments, the quality loss rate is <5% and the strength loss rate is <20%, and the performance is still stable.

Same life as building

Effectively avoid the installation and welding of stainless steel keels.Double fixation with physical anchor bolt + chemical paste.Enhanced stability, effectively saving up to 70% of steel consumption
