TEWO Wall Elements

The TWEO Element is an insulated, element made of solid wood with a hollow cavity. The element can be used in supporting outer walls, apartment partition walls (soundproofing walls/firewalls), inner walls, parapet elements as well as filling elements that have another load-bearing construction.
The groove/spring function allows the elements to fit snugly together, and also makes them simple to assemble together. The elements are supplied with mineral wool, wood fibre or without insulation for insufflation.
