Wooden formwork

Wooden formwork can be used as a substructure or external façade cladding. It usually consists of profiled boards.

Profiled boards are small-scale and therefore allow a high variety of designs. At the same time, the repair effort in the event of damage is rather low, as individual boards can be easily replaced.

A variety of local woods are suitable for wooden formwork, e.g. spruce, larch, fir, pine, Douglas fir and oak.

Profiled boards are manufactured with different profiles, which influence the joining and thus the appearance. For example, the design can be carried out in the form of a lid or inverted formwork. The boards can be aligned vertically, horizontally or diagonally. Different profiles are, for example:

• boards - parallel edged
• strips/boards - the narrow surfaces have an inclination of at least 15° on
• boards, spun - with tongue and groove
• bevel boards, spund - chamfered on the upper side, with tongue and groove
• inverted formwork boards - with tongue and groove, on the spring side the edge is concave rounded
• Boards with shadow groove - with tongue and groove, edges chamfered on the visible side, wide ground on the spring side

Profiled boards belong to building material class B2.

Profiled

boards for timber formwork are available in different lengths and widths. The wood moisture content should be between approx. 12 and 18% during installation. When selecting size, dimension and joint spacing, the swelling and shrinkage of the wood must be taken into account.

If the wooden formwork is to be coated, it must not have any cracks in the surface and no resin galls.
