Fire-resistant pillow, 120x300x35 mm DB1805 DKC

Fire-resistant pillows are designed for installing penetrations at the intersection of walls or floors with metal trays. The penetration consists of tightly packed pillows, whose shell is made of fire-resistant fabric, and contains a thermo-expanding filler inside. Under the influence of high temperature (>200 °C), fire-resistant pillows swell by more than 40% of their original volume, thereby forming a tight seal that prevents the further spread of open flame and heat. Pillow dimensions - 120x300x35 mm.
