Wall elements

Wall elements and facade elements 

The outer surface of a facade element is usually made of facing tiles, flat or brushed concrete or otherwise finished, such as washed or fine-washed surface. The concrete used for the manufacture can be ordinary grey concrete or one of the various sorts of grain or colour concrete.

Facade slabs are divided into two categories on the basis of their technical functions: bearing and non-bearing facade elements. In terms of their structure, the elements are divided into sandwich elements and thin-shell panels.

The structure of sandwich elements consists of an outer and inner skin made of concrete, with thermal insulation in between them. The insulation can be mineral wool, polyurethane or polystyrene. The skins of sandwich elements are joined together using trusses.

Thin-shell panels consist of only one concrete shell and do not usually include thermal insulation. On the basis of their uses, thin-shell panels are divided into strip and square panels. The form of the element together with the length of series is an important factor with respect to the manufacture and the working time and lead time required by it.

Facade elements are poured using flat casting. The base material of the mould is usually plywood or steel.

Partition panels

Partition panels are typically 80-200 mm thick, planar objects that are poured using either flat casting on mould tables or vertical casting with battery moulds. The advantage of products made in battery moulds is the evenness of both surfaces (steel mould surface).
