Wood is a natural and renewable resource that will continue to gain significance as a building material.
As demands in the construction industry grow, e.g. in the area of thermal and sound insulation, and the desire to avoid the use of chemicals to preserve wood increases, it will be essential in the future to focus more on the analysis of correlations in structural physics and to implement these in concrete plans.
This also applies to the construction of new and the renovation of existing buildings. The advantageous material and technical properties of wood are ideal for this and can be used to prevent damage in the long term.
According to DIN 68800, the intention is to avoid the use of chemical preservatives in preventive wood protection. It is therefore necessary to incorporate constructive wood protection in the early stages of planning in order to reliably avoid damage to the wood building materials.
The layered structure of the components must be examined in terms of the moisture balance. Transient calculations support the development of structural components as part of innovative solutions and make it possible to forecast the hygrothermal behavior, e.g. of flat roof constructions, in real weather conditions many years into the future.
In addition to standard structures, detailed design is of particular importance in timber construction. Measures are developed here to ensure absolute air tightness and to derive details for constructive wood protection. Additional factors must be considered in the renovation of old buildings such as possible preexisting damage and the effects of modernization measures.
The necessary renovations in terms of thermal insulation have a profound effect on structures that have functioned well for many years. For instance, beam ends in wood-beamed ceilings can be exposed to harmful moisture build-up after interior insulation work has been completed.
To meet this challenge, it is necessary to examine the existing building using largely non-destructive examination methods such as drill resistance measurements or endoscopic techniques. If there is damage to the structures, e.g. due to harmful mold such as true dry-rot fungus or insects, this can be determined and appropriate targeted restoration measures can be developed.
We are specialists in the following areas:
- Constructive wood protection in the early stages of planning
- Determination of the hazard or use classes (use of chemical wood preservatives)
- Proof of new structures in new and existing buildings using simulation calculations
- Examination of wooden structures in existing buildings with regard to wood damage due to mold and insects
- Use of largely non-destructive examination methods such as drill resistance measurements and endoscopic techniques
- Development of restoration concepts in accordance with DIN 68800
- Verification of the execution quality, e.g. using airtightness measurements
