A glass wool sandwich panel has an excellent incombustibility, so 100㎜ thickness of sandwich panel has got 1hour fire resistance identification. But after the fire resistance test method has been changed, most of glass wool sandwich panels couldn't get 1hour fire resistance identification.
As the result of this changed method, the sandwich panel wall needed to reinforce. So nowadays a identified sandwich wall has thicker U-bar, higher glass wool density, and thicker panel thickness than before, involving girth reinforcement. But a sandwich wall reinforcing girth has some problems, which are different construction class between sandwich wall and girth, and no application to the wall without girth. This research studied composition methods of glass wool sandwich panel without girth reinforcement having 1 hour fire resistance and the results were as follows.
The glass wool sandwich panel wall composed with 125㎜ thickness of panel, 70㎏/㎥ of glass wool density, 1.6mm of U-bar thickness couldn't get 1 hour fire resistance although joint was reinforced with steel stuffs and ceramic wools.
The 150㎜ thick sandwich panel without girth could get 1 hour fire resistance if U-bar thickness was 2.0㎜ and ceramic wool thickness doubled or steel stuffs were reinforced on joints although glass wool density was decreased to 64㎏/㎥.
A sandwich panel composed with 150㎜ thickness and 74㎏/㎥ of glass wool density could get 1 hour fire resistance using normal assembly method without girth reinforcement.
