Transcript of TypesofCE RISfi cem ent bonded particleboard
CETRIS® cem ent bonded particleboard is a construction m aterial of excellent qualities. It is best suited for the floor system s, attic adaptations and the loft superstructures, ventilated façades, fire protection applications, fascias, ceilings, w alls and partitions and different sm all garden item s.
CETRIS® cem ent bonded particleboard can be found in all kind of prefabricated constructions.
It is ideally suited for the dry building technologies, projects built in adverse clim atic conditions
and other applications, w here all of the unique positive properties of this m aterial can fully develope.
Types of CETRIS®
cem ent bonded particleboard
CETRIS® cem ent bonded particleboards are produced by pressing a m ixture of w ooden particles, portland cem ent and hydratation additives. The surface is sm ooth; the color is cem ent-like grey.

Cem ent bonded particleboards are used preferably in
such cases, w here m oisture resistance, m echanical
strength, fire resistance and ecological cleanness are
required at the sam e tim e. CETRIS® boards contain
neither asbestos nor form aldehyde. They do not get
m ouldy and do resist insects.

A basic type of the cem ent bonded particleboard w ith a sm ooth cem ent grey
surface. The standard production thicknesses are 8, 10, 12, 16, 18, 20, 22,
24, 26, 28, 30 and 32 m m . O n special request also boards 34, 36, 38 and 40
m m thick can be produced.
The basic size of the board
is 3350 × 1250 m m . The
boards can be delivered
cut dow n to a specified size.
The edges can be straight
or rounded or cham fered at
45° angle. They can be also
m illed to the sem igroove
(12 m m or thicker boards)
or the tongue-and-groove
(16 m m or thicker boards)
profiles. Holes can be also
predrilled in the boards.
A basic cem ent bonded particleboard in the size 1250 × 625 m m (including
the tongue) designed for dry flooring system s. The standard thicknesses of
the CETRIS® PD are 16, 18, 20, 22, 24, 26 and 28 m m . O ther thicknesses
can be delivered on special
request. The boards are
furnished w ith tongue-and-
groove profile around all
edges. They are designed
to be laid on beam s or on
old floors that are being
renovated.
A sanded cem ent bonded particleboard in the size 1250 × 625 m m (including
the tongue) designed for dry flooring system s. The thickness tolerance is
reduced by sanding to
less than ± 0.3 m m . The
standard thicknesses of
the CETRIS® PD are 16, 18,
20, 22, 24, 26 and 28 m m .
O ther thicknesses can be
delivered on special request.
The boards are furnished
w ith tongue-and-groove
profile around all edges.
They are designed to be laid
on beam s or on old floors
that are being renovated.
A cem ent bonded particleboard 8 to 32 m m thick w ith a sm ooth surface. By
special order also the boards 34, 36, 38 and 40 m m thick can be produced.
The surface of the board on both sides and all edges is treated w ith a
w hite prim er. The prim er
can be applied in a single
or double layer. The
basic size of the board is
3350 × 1250 m m . O ther
services (custom izing)
can be ordered sim ilar as
w ith the CETRIS® BASIC
board. The prim ing
m akes the final top
layer stick better to the
board and reduces the
consum ption of the top
layer paint.
A cem ent bonded particleboard 10 to 32 m m thick w ith a sm ooth surface,
prim ed and painted w ith a finish paint. The colours can be ordered by a
sam ple table. By special order also the boards 34, 36, 38 and 40 m m thick
can be produced. The
basic size of the board is
3350 × 1250 m m . O ther

board. CETRIS® FIN ISH
boards are used m ainly
as façade cladding
panels.
A cem ent bonded particleboard 10 to 32 m m thick w ith a layer of crushed
m arble grains on the top surface. The grain size and colour can be ordered by
a sam ple table. By special
order also the boards 34,
36, 38 and 40 m m thick
can be produced. The
boards are produced in
various sizes. CETRIS®

The interior cem ent bonded particleboard w ith thickness of 10 – 32 m m is
w hole-area tw o-sided sanded. The face side and edges are painted w ith
a w ater-based sem i-transparent paint (7 colours). A protective coat is
applied on the back side.
The boards are supplied in
rectangular form ats of m ax.
size 3350 x 1250 m m . The
boards CETRIS® LASIN are
intended for decorative use
in the interior – cladding of
w alls, building of w affle
floors, etc. The surface
finish creates covering
layer resistant against U V
radiation and abrasion.
The cem ent bonded particleboard w ith thickness of 10 – 32 m m coated w ith a w ater-
based acrylic sem itransparent paint (7 colours). The coating of the cem ent bonded
particleboard CETRIS ®
LASU R increases resistance
against clim atic influences
and significantly decreases
the board rate of absorption.
The boards CETRIS® LASU R
are m ainly used as a facing
of vented façade system s.
W e supply these boards in
sizes according to the w ish
of a custom er (m ax. 1250 x
3350 m m ). The boards can
be supplied w ith predrilled
attachm ent holes and
m odified edges.

CETRIS® cement bonded particleboard combines the virtues of cement and wood. It is lighter than a common cement fibreboard. Considering its strength, stability in moisture, weatherproofness, frost and mould resistance, it is much better than chipboard or plasterboard.
Storage of the CETRIS® boardsThe CETRIS® boards must be stored in covered and dry areas so that the boards do not get wet before they are installed. For storage, CETRIS® boards may be stacked in more layers provided that they are of uniform size.
Q uality certificatesThe producer pays steady attention to the quality of the production. The production plant has been certified according to EN ISO 9002 since the year 1996. In the 2004 it was recertified to EN ISO 9001:2000 by the internationally accredited certification body Lloyd’s Register Q uality Assurance. The production process is supervised by independent testing institutes.
CETRIS® holds CE-certificate according to EN 13986 since June 2004. CE-certificate rounds up the overall technical certification and declares the conformity of the products anywhere in the European markets.
