High-absorbent noise barrier (Wooden)
Wooden noise barrier systems meet all important environmental
and maintenance standards set by architects and landscape planners.
Wood is an ideal material with respect to natural appearance
and flexible design.
|Outstanding features at a glance:
|Sound insulation in accord with DIN EN 1793-2
|Acoustic absorption in accord with DIN EN 1793-1
||Centre line measurement minus 4.0 cm
||Up to 6.00 m
||Impregnated pine; or
alternatively larch timber with no
||Screws, ribbed nails made from
stainless steel in accord with
V4A as per DIN 267, part 11
All elements are vertically assembled. Special sizes are possible
to customize terrain-alignment segments as well as for integrating
doors and gateways. Structural design is achieved through vertically
Wood can be well preserved by profiling its cross-sections
in an appropriate manner. Chemical preservation of wood is possible
using boiler-pressured impregnation in accord with DIN 68 800,
or optionally with CKB salt (containing chrome) or CX salt (chrome-free).
The colour tone is green. Other colouring is possible on a limited
basis. The impregnation is resistant to salt used for melting
purposes and is not impaired by plants. Wooden barriers are especially
well suited for supporting climbing plants.
Profiled, horizontal wood railings above and below. Vertically
arranged tongue and groove planking (30 mm) is nailed from the
reverse side of the wall to this framing. Exterior to the planking
and including a 60 mm hollow space, an absorption plate with
a conduit density
of > 1000 N/cbm is attached and concealed on the front side
with black fibre glass batting. The barrier surface which is
to be impacted by noise is covered with poles that have been
flattened and nailed vertically (flattened diameter 54 mm x 40
mm, separated at the core and milled). Vertical wooden filling
elements are assembled to the pole connections and are milled
in order to incorporate compression sealing tape. The wall is
additionally stabilized on the reverse side with wedges.
