The origin of the tree goes back to China and Japan. Since 2600 BC, Paulownia has been considered a sacred tree and a symbol of good luck. In Asian countries, the tradition of planting this amazing tree was created after the birth of a girl in the family. After that, on the day of the girl’s wedding, the trunk of the tree was cut and a wooden box was made from it to carry the girl’s furniture. Foresters point to Paulownia’s resistance to temperature as well as attacks by parasites and insects.

The achievements of Paulownia affect the industry, assuming that 2000 trees are planted per hectare, after about 5-7 years, about 200-300 tons of wood with qualitative parameters can be harvested.

The thermal value of Paulownia is similar to birch, about 15.5 MJ/kg (wood moisture: 20%).

Optimistic forecasts says that under favorable weather conditions, a 5 to 7-year-old farm can produce about 100 tons of Paulownia wood per year.

An Attractive Material: 8 Facts About Paulownia Wood

1. Kiri tree, from the fast-growing paulownia family, is the fastest-growing tree in the world, and its wood is among the lightest. It weighs only 250 to 350 kilograms per cubic meter, which is roughly one-third the weight of oak per cubic meter. Paulownia’s low weight makes it an ideal construction material where every gram matters: boat and shipbuilding, tiny houses and caravan sections, interior furnishings, packaging, and sports equipment like surfboards and skis.
2. This wood has a honeycomb-like cellular structure, which makes it incredibly strong relative to its weight, giving it exceptional stability. Hence, paulownia wood is known as the “aluminum among woods.”
3. Unlike many other types of wood, paulownia wood is highly suitable for outdoor use. Its special properties mean that it dries very quickly, helping prevent the growth of moss, fungi, and mildew. Burckhardt Institute at the University of Göttingen conducted months-long experiments confirming that even after long-term exposure to weather, paulownia wood does not split, warp, or crack.
4. As the tree grows, it traps a relatively large amount of air within its cells, giving the wood excellent insulating properties. Paulownia wood’s insulating ability is approximately twice that of oak (thermal conductivity for paulownia: 0.09, oak: 0.2). This makes it ideal for constructing saunas, houses, engine rooms, doors, windows, curtains, and even for cladding the facades of buildings.
5. Paulownia wood is dimensionally very stable, even in environments with fluctuating humidity. It has very minimal expansion and contraction.
6. The wood has a light color, with a fine and consistent grain pattern, and its surface is notably smooth and pleasant to touch. Only grade one paulownia wood from European farms is placed in the KIRITEC range. Their very straight trunks are virtually branch-free, providing exceptionally high-quality, smooth-looking wood. This is why high-grade paulownia wood is particularly suitable for use in places where appearance matters, such as furniture making, coffins, and musical instruments. In Japan, it’s traditionally used to make kimono wardrobes.
7. Paulownia wood has a relatively high ignition point: it only ignites at temperatures above 400 degrees Celsius. In comparison, a pine tree’s ignition point is only 225 degrees Celsius.
8.  Processing paulownia wood, whether by hand or mechanically, is very easy and versatile, whether as plywood, glued boards, solid wood boards with a wood core, wood chips, or three-layer boards. The boards and products made from paulownia do not splinter but absorb paints and stains well.”
