SAWN TIMBER

UPM Timber product range covers both standard and special sawn timber made of Nordic pine and spruce. The difference between standard and special sawn products is largely based on sawing and drying methods as well as length and grade selections. Our special sawn timber range carries the name UPM+.

Log cut in pieces 

UPM's sawmills across Finland utilise local certified raw material and its properities to produce high quality standard sawn goods from spruce and pine logs. UPM offers fast and flexible deliveries as well as an extensive range of dimensions in standard grades.

Product standars define the dimensions and moisture contents:

  • EN 1313-1: sawn timber standard dimensions and grades
  • ISO 738-1981: allowed dimensional variance and shrinkage 
  • INSTA 141: moisture content

 

Standard moisture content is 20 % (+/- 2%).
