Material
Porous soft fibreboard is manufactured
from spruce, fir and pine pulp in a wet
production process. Fibre humidity
exceeds 20 per cent during the manufacturing
process.
The raw density of soft fibreboard lies
below 450 kg/m ;i , making it lower than
that of medium hard and hard fibreboard.
Application®
Soft fibreboards are used as insulation for
floors, walls, ceilings and roofs; they are
also employed as impact sound insulation
under floor screed, dry screed and wood
flooring, and as sound absorbing panels.
Depending on the application, the boards
are connected by butt joints, rebate joints
or tongue-and-groove joints. The panels
are loosely laid and then mechanically
fastened or glued. Special joint adhesive
sealing may be required to ensure air
tightness.
Like untreated wood, wooden fibreboards
must be protected against UV-radiation
and humidity. With a wood moisture content
of less than 20 per cent, these
boards are highly resistant to wood pests
and other sources of damage (bacteria,
fungi, and insects).
Wood fibreboards are available as insulating
plaster-base elements for exterior
walls. They are also suitable as elements
for composite or sandwich construction in
combination with hardboard or gypsum
board.

Manufacture
In the wet manufacturing process, waste
(rom locally harvested coniferous trees is
chipped and shredded. The chips are
pulped with vapour in a reaction chamber
and subsequently milled into fibres. Additives
and, if required, wood preservatives
are blended into the fibre slurry. The
slurry is spread on a Foudrinier to create
a flat fibrous mat, which is then dehydrated
by extrusion or by applying negative
pressure. In the final stage, the mats
are shaped into boards and dried.
Thicker panels (25-30 mm and upwards)
are manufactured by laminating several
individual boards.

Material
Bituminated fibreboards are porous wood
fibreboards, manufactured with a bitumen
additive.
A distinction is made between bituminated
(ibreboards
• with 10-15 per cent bitumen additive
(moisture-proof) and a water absorption
rate of less than 25 per cent (BPH)
• with more than 15 per cent bitumen
additive (increased moisture resistance)
and an average water absorption of less
than 20 per cent (BPH2).
Application®
The primary areas of application ar& exterior
walls, roof extensions and subfloors.
Bitumen-impregnated wood fibreboards
can be used under roof covering as
water- and airtight layers. The bitumen
content renders them resistant to moisture,
rot, fungi and insects.

Manufacture
Bituminated wood fibreboards are manufactured
in the same manner as porous
wood fibreboards; the only difference
being that a bitumen emulsion is added
to the fibre slurry.
