Plywood made of Angarsk pine
- hangar pine wood involves high density - 540 kg / m3, which is 1. 5 times higher than the average density of pine in the middle part of the European continent.
- Angara pine wood has high mechanical strength and low thermal conductivity.
- Flexible wood, which makes it resistant to sudden changes in temperature and humidity
- High resistance to fungal infection
- Due to the combination of high density and high content of this type of resin is resistant to rot.
