Wood modification, particularly the thermal modification, is one of the special business fields of the Institute for Wood Technology Dresden (IHD) for many years. IHD has been established here as an internationally accepted partner.

Services and activities are, in particular:

  • Research projects on product and technology development
  • Provision of specific information, technical TMT leaflets
  • Organising the European TMT Workshop (biennial)
  • Thermal modification of wood and wood-based materials thermokiln
  • Classification and assessment of thermally modified timber (TMT)
  • Certification programme "Quality Mark TMT" (operated by EPH)

Services Biology

  • Wood knowledge; Determination and assessment of wood properties and quality
  • Wood protection; Damage analysis and expert reports
  • Microscopic determination of harmful organisms (fungi, insects, bacteria)
  • Microscopic/microstructural investigations (coatings, glue lines, compartments)
  • biomolecular diagnostics of fungi by DNA array (proof of 24 building rot fungi) and ITS sequencing
