Welcome to RETROTIMBER
We combine the appearance of old wood with the static properties of new wood
The superior alternative to old timber
RETROTIMBER is specially treated timber, mainly from spruce and larch, which has the appearance of old timber while retaining structural properties that are comparable to untreated timber. The idea for RETROTIMBER originated
from steamed timbers, which have been long been used,
especially for decorative purposes. RETROTIMBER has the same visual properties as heavily steamed wood, but without significantly altering its original structural properties.
For use in the construction sector
Compared to conventional steaming, the special RETRO treatment is much more complex and time-consuming. The timber is treated very gently in order to influence its properties as little as possible. The treatment is only intended to significantly change the appearance of the timber. Additional surface treatment (brushing, hacking), renders RETROTIMBER almost indistinguishable from old timber. Since the structural properties following treatment are known, RETROTIMBER can be structurally determined and is particularly suitable for use in structural applications.
European technical assessment (ETA)
RETROTIBMER has been issued European technical assessments (ETA). ETAs certify the technical usability of a product within the meaning of the EU regulation on construction products. They are based on highly extensive tests conducted by test institutes specifically accredited for this purpose. An assessment covers all the important product characteristics of a construction product. Thanks to this safety of our construction products for structural use in accordance with the requirements of the Construction Products Directive. Please also note that you do not have this safety when using common old timber products or other thermally treated woods. ETAs give construction companies the certainty of using a suitable product for structural use.
RETROTIMBER has two European technical assessments:
Structural timber ETA-16/0706
Glued laminated timber ETA-17/0393
ETAs give construction companies the certainty of using a suitable product for structural use.
