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

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.

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.

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.
