Влияние теплоизоляции из полимерного пенокомпозита Penocom на огнестойкость ограждающих деревянных каркасных конструкций

Abstract

Sing a small-scale fire tests three separating construction assemblies modeling fragments of walls and partitions in timber buildings of light frame type have been studied. As a thermal insulation layer have used a commercial polymer foam composite "Penocom" with different density between 43.7-140 kg/m 3 . It was established that the actual limit of fire resistance of separating constructions for the integrity and insulating capacity (EI) was 95-110.3 min. It was found that there is a tendency: increasing the fire resistance of four-layers structures corresponds decreasing the density foam composites "Penocom" from 83 to 43.7 kg/m 3 . The average values of the heat flow in the small-scale fire oven at the standard mode of fire at different periods of fire actions have been measured as well. These values correspond the relationship found at standard large-scale apparatus. Thermal conductivity of polymer foam composite was calculated.
