本研究以開發外牆開口部之新材料為研究方向，目的是希望開發有關層間牆改善之替代防火區劃部品，利用柴油為燃料之高溫爐進行火災標準試驗，模擬裝置於外牆開口部之替代防火區劃部品的火災行為，以得知該防火區劃部品之防火性能。經試驗後本研究獲致下列結論：
一、試驗爐之爐壓及爐溫符合CNS 12514要求標準下，在時間為30分鐘，平均爐溫為810℃時，輻射熱為106.3kW/m2，在時間為60分鐘，平均爐溫為946℃時，輻射熱為149.4kW/m2。所量取之輻射熱值均較Sultan之小型試驗爐(Intermediate-Scale Furnace)及大型試驗爐(Full-Scale Furnace)為高，證明本研究所使用試驗爐具有一定程度之代表性。
二、百葉之簍空縫隙較多者，塗料厚度對降低輻射熱之助益較少。實驗最大輻射熱為1.271 w/cm2，發生在「第Ⅰ型」未噴塗塗料且距離火源0.5 m之位置。不論是否噴塗塗料，當距離與火源超過1.0 m以上時，最大輻射熱亦低於1.0W/cm2。
三、相同網徑及塗料厚度下，網目愈小，阻擋輻射熱之效果愈佳。在相同網徑及網目下，塗料厚度愈大，阻擋輻射熱之效果亦愈佳。鐵網經噴塗ㄧ定程度之膨脹性防火塗料後，可達到1小時防火時效遮焰性之等級。
四、網目為#4、#8及#10時，當塗料噴塗兩層之厚度，其60分鐘時之最大輻射熱可降低至木材之輻射引燃值1 w/cm2以下。
五、本研究提出之新材料應用觀念，不僅可以保持採光及通風的功能，更可以達到阻止延燒的目的，可依建築性能化設計之觀念，應用於建築物之特定位置，本研究雖僅以少數百葉及鐵網做為樣本，但應用概念確實可行，只要活用，即可將各種百葉、鐵網及不同之塗料厚度進行適合之搭配。

The study focused on new building material using in openings of external wall which main to develop alternative fire barriers on fire compartment, the use of diesel fuel in standard furnace for fire test to determine the fire behavior of new fire device to confirm the fire performance of the new component. After to the tests, the followings are obtained: First, According to the criteria on furnace pressures and temperature in CNS12514, when the furnace operated in good condition, in 30- min time, required average temperature is 810℃and radiant heat is 106.3 kW/m2, in 60-min time, required average temperature is 946℃and radiant heat is 149.4 kW/m2. The tested average radiant heat is higher than tested both in intermediate-scale and full-scale furnace. This verified the test furnace used in this study is representative. Secondly, the louver empty areas more, the thickness of coating to reduce radiant heat is less helpful. From the fire source 0.5m, the experiment 1.271 W/cm2 was measured in non fire spray coating of type-Ⅰ louver. With or without fire coating, when the distance from fire source more than 1.0m, the maximum rediant heat is also under 1.0 W/cm2. Thirdly, the less the smaller span of iron mesh using the same wire diameter and coating thickness provides better heat insulation; a same span of iron mesh with the thicker coating and the same diameter improves resistance to radiant heat. Iron mesh sprayed on certain amount of intumescent fireproof coating can provide 1 hour fire rated integrity. Fourthly, #4, #8 and #10 iron mesh sprayed double-layer coating were found the maximum radiant heat at 60-min can be reduced to 1 w/cm2 which as the ignition radiant rate in wood. Lastly, the concept of new-material application in this study provides not only nature light and ventilation performance but also preventing fire spread and can be applied in performance-base design buildings for special spaces. Although only few iron mesh specimens were tested but it proves the test method is applicable. The various iron mesh with different coated thickness can be proceeded in utilizing the concept of this study.
