Influence of natural weathering on the ignition and relative burning rate of selected softwoods
Original language description
In recent decades, coniferous facade boards from untreated wood have been used extensively without the use of biocides, flame retardants and weather protection coating systems. This work is focused on testing selected properties of 4 untreated softwoods -spruce, larch, pine and Douglas fir -exposed outdoors for 3, 6, 12 and 24 months during direct flame exposure. When exposed to outdoor conditions, all of the wood species significantly changed colour to grey shades, while the highest roughness changes were observed in spruce. FTIR analyses confirmed a significant decrease in lignin in surface layers due to weathering. After 3, 6, 12 and 24 months of weathering, all of these measured characteristics had no significant effect on changes in ignition and relative burning rate of the tested wood. The tests confirmed the higher effect of the wood species compared to density influence, wherein pine had significantly higher mass losses and burning rate compared to Douglas fir, spruce and larch.
