19.07.2023. Times are changing: building sustainably and responsibly is no longer a desire but a requirement (RE2020). The supply of raw materials is becoming more difficult and costs are rising, all of which is driving the construction industry to design differently.

We have the solution: glulam and finger-jointed timber.

Because we focus on the quality of materials, our hybrid “durability-technology” offer will make it possible to respond to the latest requirements, for new buildings or renovation.


By optimising the material (wood) with highly engineered products harvested from the forest that IHC manages responsibly (Forest Stewardship Council, FSC® C022952) in the Republic of Congo. Industrially produced, they combine durability and time-saving processes.
