火災發生時，煙毒除從建築物開口部的流竄、擴散，是造成人命傷亡的主因外，帷幕牆防火層間塞之遮煙性亦會影響上層使用者之逃生可能性。本研究藉由實尺寸之帷幕牆層間塞之模型配合CNS15038所衍生遮煙之量測空氣洩漏量裝置進行相關遮煙性能，針對不同岩棉密度、厚度、線性開口大小及附加材質，來檢討目前帷幕牆安全設計法應用於評估層間塞之洩漏量。經試驗結果得知如下:
1. 岩棉密度80㎏/m3比60㎏/m3洩漏量減少約為11％。
2. 岩棉密度80㎏/m3及60㎏/m3共有三種不同厚度遮煙效果，岩棉厚度遮煙效果為15cm＞10cm＞5㎝。
3. 線性開口大小與層間塞洩漏量呈正比關係。線性開口尺寸洩漏量最高為30cm＞20cm＞10㎝。
4. 鋁箔岩棉比一般岩棉密度為80㎏/m3及60㎏/m3有效抵擋煙氣洩漏量減少約為42％。
5. 岩棉在中溫狀態時洩漏量會比常溫狀態時洩漏量小。在中溫狀態下比常溫煙氣洩漏量減緩約為40％。
6. 岩棉煙氣洩漏量的問題在於岩棉密度而不是在於岩棉與樓板銜接介面洩漏問題。
7. 一般業界在線性開口部有施作層間塞，都會符合”IBC713.5 Penetrations in smoke barriers”及”IBC 714.6 Fire-resistant joint systems in smoke barriers”最低要求數值。

The purpose of this study is to establish a method for smoke leakage testing of
curtain-wall through-penetration firestop to operate in coordination with CNS 15038 conforming apparatus. There is a model with rock wool to test with leakage testing apparatus. Use variable for different density, thickness, linear dimension and attachment material of rock wool.
This research first makes the preliminary understanding on building smoke calamity and rock wool characteristic. Using smoke simulates carries on the experiment, picking up rock wool different material smoke leakage and the destruction pattern to provide the improvement suggestion. The results from the test are listed as below:
1. The rock wool density 80㎏/m3 compares 60㎏/m3 the smoke leakage to reduce approximately 11%
2. The rock wool density 80㎏/m3 compares 60㎏/m3 have three different type thickness, rock wool thickness smoke barriers the smoke effect for 15cm>10cm >5㎝.
3. The linear dimension and rock wool air leakages are direct ratio relations, the linear dimension smoke leakage is highest sequences for 30cm＞20cm＞10㎝.
4. Using rock wool with aluminum compare to the single rock wool unit, rock wool of aluminum smoke barrier better single rock wool unit, which smoke leakage decreased about 42%.
5. The rock wool leakage in medium atmospheric temperature rather than in normal atmospheric temperature air leakage decrease about 40％.
6. The rock wool with leakage problem is for rock wool thickness, is not rock wool connects with floor interface problem.
7. General constructions have infill rock wool of layers for fireproof, that fit “IBC standards 713.5 Penetrations in smoke barriers leakage” value and ”IBC 714.6 Fire-resistant joint systems in smoke barriers”, conforms to the lowest requirement.
