According to "NFPA" fire statistics, the cause of fire death analysis, the proportion of structural damage death is 5%, the proportion of direct fire death is 20%, the proportion of toxic smoke death as high as 75%. The role of smoke prevention and exhaust pipe provides time and conditions for personnel safety. This also has high requirements for the performance of smoke prevention and exhaust pipes: a. Safe structure, integrity, and prevention of fire; B. Non-combustible heat insulation, avoid combustion and ignition, combustion support.

Smoke control and exhaust duct is the air duct of the mechanical pressurized air supply and smoke control system that is set through the building according to the requirements of the design code, or is located in the fire danger zone, and the machine across the fire zone. Air duct of smoke exhaust system.

Uetersen latest product:

As an advocate of building energy conservation in China, Uetersen has developed the uttson fire and smoke exhaust system ventilation pipe dedicated to smoke prevention and exhaust system. It is composed of galvanized sheet + rock wool (50mim) + fire prevention board, their fire resistance limit in the 9mm smoke control system ventilation pipe can reach 120min, 12mm smoke control system ventilation pipe can reach 180min.

Calcium silicate fiber is an excellent fireproof material in many kinds of fireproof boards.  In many years of various fires, calcium silicate fiber fire prevention board as A1 non-combustible grade in fire prevention building materials stand out.

Hazardous smoke emitted during a fire

Rock wool as a basalt fiber material, applied in the field of heat preservation, thermal insulation, sound absorption noise reduction, high mechanical fire performance, the above performance is rock wool fiber through the formation of the adhesive chamber to achieve. The fiber diameter of the fire and smoke exhaust system ventilation pipe is below 5μm. The fiber diameter distribution is uniform, and the strength is better than ordinary rock wool. The consistent length makes rock wool smooth and soft, and the processing is more convenient.

Uetersen smoke control pipe channel with rock wool as the core, rock wool core material is specially designed for metal sandwich board rock wool products, with good fiber, uniform spray glue, including adhesive, hydrophobic agent spraying uniform.

Uetersen new product: smoke control and exhaust system pipe

Is fire prevention board, calcium silicate fiber is lime, Portland and inorganic fiber reinforced materials as the main raw material of building plank, have qualitative light, high strength, good durability, insulating and stays processing performance and construction characteristics of excellent performance, mainly used in ceiling, partition wall as well as for the fire protection of the steel columns, steel materials.

Galvanized sheet + rock wool (50mm) + fire prevention board three layers of A1 protection, both heat preservation and fire prevention, fully meet the "Building smoke Prevention and exhaust system technical Standard" GBhttp://m.nmnyaamb.com.cn/2http://m.nmnyaamb.com.cn/ on fire resistance and heat insulation requirements of smoke prevention and exhaust system.  Uetersen advanced production process control process and advanced production line always ensure the excellent quality of Uetersen, whether in the construction process or in the future long-term use process can provide users with high quality fire control and smoke exhaust effect.

Uetersen fire exhaust system ventilation duct before and after fire comparison

Uetersen fire protection board class A1 does not burn, no black smoke output.

With years of experience in thermal insulation industry, Uetersen  has summarized the experience of people before and after, and constantly improved, updated and iterated utsen's products, so that the green thermal insulation materials can bring high quality fire protection, heat preservation and moisture-proof effect for customers in the most excellent state.

Uetersen mission is to protect life and make the environment sustainable by building materials that are fire-resistant, energy efficient and comfortable. We firmly believe that our products will be used in more fields and play a greater role in solving social and environmental problems in the future. We will constantly update our new products, so that you can easily build a beautiful comfortable and safe space.
