Differences between heat treated Pinus pinaster heartwood and sapwood

, 2012
Heat treatment is a well known process to improve the durability and dimensional stability of less noble wood, The treatment can be applied for heartwood unlike the traditional treatments based on impregnation due to the difficulty of impregnating ...

Effects of moisture content on the behaviour of Scots pine heartwood and sapwood under impact

Journal of Wood Science
The material properties of sapwood and heartwood vary within various wood species and even they can show significant differences within a single tree. Scots pine (Pinus sylvestris L.), a species that plays a crucial role in timber production for joinery ...

Radial Distribution of Lipophilic Extractives in Walikukun (Schoutenia ovata Korth.) Wood

South-East European Forestry
Walikukun (Schoutenia ovata Korth.) is a commercially significant wood species in Indonesia. Heartwood, in particular, is important due to the natural durability and aesthetics, while lipophilic extractives play a crucial role in the formation. Therefore,

Treatment variation along the board of furfurylated sapwood and heartwood

, 2014
Wood modification by furfurylation depends on impregnation, so only some species can be treated and even so generally only sapwood samples can be used. Another question is that if the impregnation is not even the properties may vary along the board. The
