Wood-cement block without thermal insulation
The IZOBLOK wood-cement block without thermal insulation serves as sacrificial formwork for filler concrete and a carrier of plasters. These blocks are most frequently used for inner bearing walls and partitions and have excellent noise insulation. They can also be used as bearing perimeter masonry, which is additionally heat insulated.
