Stacks should be weighted down for best seasoning results Kiln Drying Rate Drying rate is fairly rapid to fast Naturally dries quickly Rapid Tree Size Tree height is 10-20 m Tree height is 0-10 m Sapwood width is 0-5 cm Sapwood width is 5-10 cm Bole length is 10-20 m Tree height is 20-30 m Trunk diameter is 150-200 cm Trunk diameter is 100-150 cm Tree height is 30-40 m Bark width is 10-15 mm Product Sources Although the generic vernacular name of Vatica is Resak, the name has been used to refer to other species. Vatica timbers are very similar in characteristcs to those of Cotylelobium, and they are usually combined and marketed together under the trade name, Resak.
