galvanized steel eps sandwich panel | |||
Name | Glass wool sandwich panel | EPS sandwich panel | Rock wool sandwich panel |
Density | 64kg/m3 | 5-20kg/m3 | 80-120kg/m3 |
Heat Exchange Factor | 0.032 -0.037(m·K) | 0.035-0.042(W/m·K) | 0.041-0.045(W/m·K) |
Fire resistance | Noncombustible A level | C ~ D flammable, plus flame retardants into class B flame retarga | Noncombustible A level |
Smoke toxicity | Inorganic flame retardant materials, non-toxic
| The combustion release toxic gas | Inorganic flame retardant materials, non-toxic
|
Skin irritation | Fine fibers, no shot, Fine fibers, no shot, no stimulation of the skin | No stimulation of the skin | The fiber coarse cause itching, slag ball lead thorny affect construction |
Hydrophobicity | Hydrophobicity | Hydrophobicity | No hydrophobicity |
Tensile properties (Tensile properties) | 150~200mm, fiber grows insulation tensile higher performance, better seismic performance | Tensile strength of small, fragile
| ≤40mm,tensile strength of small, fragile
|
Life | No pulverization phenomenon, can use for a long time
| Long time exposure on the outside will turn yellow, brittle
| Natural powdering the life time is greatly shortened, after a period of time after the appearance of slag ball down, cotton body hanging elongated, and even rupture |
