Birch is very attractive and gives off a lot of heat, but it burns out fairly quickly. Though birch can be easier to find and cheaper than many other species, you €™ll go through it much faster. Birch is most suitable and reccomended for campfires, fire-pits, low cost pizza ovens and barbecues. Spark-free burning firewood, made exclusively from 100% sustainable sources. Only the best quality birch wood is used for production. Free of mould, mildew and pests due to kiln drying.
