A sandwich wall is composed of three layers: a facing layer, an insulating layer and a load-bearing layer. These walls are typically made horizontally and have a formwork-smooth main visible side, usually the facing layer, and a rough main visible side, usually the load-bearing layer. In a new production process using battery formwork, sandwich walls can also be manufactured with a formwork-smooth, or ready-to-paint, load-bearing shell, which reduces follow-on costs on construction sites.
