ENGINEERED WOOD
represented a gain for future viability
due to increased flexibility.
The flexibility of production at Haas
is evident in the element heights.
In Falkenberg, prior to automation,
manual production was set to an
element height of up to 3.11m. But
today, elements with heights of
1.5-3.5m can be produced. “High
walls are standard in residential
and commercial construction, since
more building technology has to be
accommodated in the floor and in
suspended ceilings,” added Haas.
High walls are also in demand for its
spaciousness and elegant ambiance in
commercial construction and modern
detached house construction.

The height of the elements ranges
from 1.2-12m long, at up to 50cm.
The same applies to the maximum
weight of 3.5 tonnes to clad these
elements with gypsum plasterboard
panels and run them through the line
without any damage, for instance. Haas
said that it was a challenge as nobody
had done it before. “This is why we
re-optimised these details of the line.
WEINMANN found solutions to meet
our requirements,” he added.
The end result was said to be a win for
both partners. With the pilot project,
WEINMANN anticipated a development
in timber construction that is a reality
today. Haas Fertigbau acquired a
production line that did exterior and
interior walls for house and apartment
construction, walls for commercial
buildings, commercial and agricultural
halls, facade systems and special
components such as gables and jamb
walls. The automated production line
ran for most that were industrially
feasible, except for a manufacturing
facility next to a wall slot.
OUTLOOK
Haas simulates production processes
digitally before running over the
actual machine twin. With the use of
Autodesk Revit, laser scanners and
tachymeters, the company is ahead
in its digitalised processes compared
to the majority of commercial
construction projects in Germany. For
the production plant, the company
is considering an extension with an
automated plaster application and a
panel processing centre to alleviate a
potential bottleneck that could arise in
certain processing configurations.
Haas said that the weighting of the
business areas will change for the
future development of the company.
“There will be a stronger shift
toward apartment construction,” he
added.
“We will invest less in detached
house construction and the quantities
will even-out again. In the long
term, the trend continues towards
apartment construction.” WIA
