When we go shopping for food, we naturally check the quality of the groceries before we buy them. Strangely enough, when building a house, customers tend to focus 99% on the appearance of the building disregarding other important aspects.
Luckily, more and more people care about how their home is going to be built and wish to build only with environment-friendly materials.
One good example of such building material is MHM (Massiv-Holz-Mauer), a cross-layered wood panel where timber boards are joined together with aluminum pins.
MHM looks a lot like CLT (cross-laminated timber) but is produced using no adhesives or chemicals.
