本研究針對在一般火場的環境下，為確保供更建築物之安全，以及有效率減緩火災發展。因此測試垂直簾幕結合水系統之實驗，探討水膜系統結合垂直簾幕之防火阻熱性能。此研究使用三種不同之垂直布幕作為試體，分別為防火布幕、一般性吸水布幕以及一般性防水布幕。並且利用小型門牆爐，此小型門牆爐在測試時溫度可高達900 °C。在實驗過程中，防火布幕試體分別結合水膜系統與未結合水膜系統，而一般性吸水布幕以及一般性防水布幕則是結合水膜系統進行實驗。
研究結果顯示，防火布幕未結合水膜系統在實驗過程中，非曝火面溫度在30分鐘時達到693 °C，而當防火布幕結合水膜系統時，非曝火面溫度在60分鐘時低於60 °C，此結果成功符合CNS14803規範。另外值得注意的是，一般性吸水布幕也有相同的實驗結果，而價格方面，一般性吸水布幕價格比防火布幕便宜，也較方便取得。而在一般性吸水布幕結合水膜系統的實驗過程中，卻無法符合CNS14803規範，其原因為在實驗過程中，由於布幕皺褶導致水膜無法均勻分佈在布幕上，最後導致布幕破損。

To ensure safety in public buildings, effective methods for suppressing the spread of fire are required. This study examines the feasibility of using a curtain with a down-flowing water film to achieve this requirement. Three types of curtain are considered, namely a commercial fireproof curtain, a simple towel curtain and vertical blinds. For all curtains, small-scale fire resistance tests are performed at a temperature of 900 °C. In the tests, the fire resistance of the commercial curtain is investigated both with and without a down-flowing water film. By contrast, for the towel and vertical blinds, the tests are performed only with a water film since otherwise, the towel and vertical blinds would immediately combust.
The results show that for the fireproof curtain without a water film, the temperature on the unexposed surface reaches 693 °C in less than 30 minutes. However, when the water film is applied, the temperature on the unexposed surface remains below 60 °C for more than 60 minutes. In other words, the curtain satisfies the CNS 14803 standard. Significantly, the same result is obtained when using the simple towel curtain. Thus, the use of a simple towel curtain with a down-flowing water film provides is an inexpensive and convenient alternative to more expensive fireproof curtains. For the vertical blinds, the experiment was unsuccessful due the heat of the furnace making the strip become wrinkled, and thus degrading the uniformity of the water film.
