Paulownia wood is a widely-used valuable timber in many industries, including furniture, aircraft and boat construction, to musical instruments. Offering the benefits of lightweight and aesthetic qualities, it is no wonder that it gains plenty of tractions and demands nowadays—even adopting the nickname of “aluminum” of the wood species. Moreover, the fact that it grows rapidly makes it an ideal choice for biomass production.
Here are some defining characteristics of Paulownia wood:
The color of Paulownia is light, ranging from yellowish-honey to light gray shade. It has silky shine surface and visually-grabbing grain characteristics because of its broad yearly growth rings.
Paulownia has a flash point of 420°C, which is about 50% higher than the average woods’ flash point at 270°C. High flash point doesn’t exactly play a big role for its use, but it creates interesting applications such as if more fire protection is needed.
This wood species only weighs around 310 kg/cubic meter in average. It makes it as one of the lightest options out there. As a comparison, American native oak weighs roughly 580 kg/cubic meter. Even the widely-known lightweight wood species such as spruce weighs about 470 kg/cubic meter. Paulownia still provides great stability regardless of its low density, making it favorable in areas that required reduction of weight such as mobile homes construction, shipbuilding, and aircrafts.
Paulownia trees provide soft surfaced wood due to the low density. It allows the wood to be crafted easily, but it also means that it is prone to damages and scratches. A proper finishing and extra treatment steps are necessary to make it more suitable for daily uses.
The required length of Paulownia timbers drying depends on how it is going to processed, as in within a drying chamber or fresh air. Opting for drying chamber can cut down the excess moisture content up to 10% to 12%. After it is dried, the wood is not likely to absorb water again, making it more dimensionally stable compared to others. In addition, it also doesn’t require swelling and shrinking steps of wood’s working processes.
Paulownia Tomentosa (PAW) has shown a great stable growth as an imported timber product, to the United States over the past ten years or so. as an exterior and interior trim product, it is clear that Paulownia wood are getting more and more popular by days due to its offered benefits and a smaller number of drawbacks.
