Dragonwood has conducted tests on the bamboo composite used to produce their products. The tests consisted of dipping test blocks in water and leaving them for a few hours. The blocks were then placed in freezing cold, up to -38 ° C! They lay there for weeks and defrosted after that. The blocks were as good as new and showed no cracks or other irregularities.
In other words: Very well applicable material in very cold conditions!
