To prevent improper design and construction of fire compartments through-penetration in buildings, and in order to reinforce public building safety management, all beams, pillars, ceilings, floors, doors, walls, and interior decorative materials must have fireproof properties. Moreover, cable conduits, water pipes, and air ducts located in through-penetration sites within buildings should be properly designed to block the spread of smoke and hot air, thus, reducing losses due to fire disasters. This study used common firestop materials, such as firestop sheets, mineral wool, and two-pack fire barrier foam to conduct 10-min surface burning tests on individual substrates. The flame spread distance and smoke per minute were measured and recorded in order to calculate the Flame Spread Index (FSI) and Smoke Developed Index (SDI). The results showed that all three firestop materials meet with the ASTM E84 Class A.
