WHERE ARE THEY USED?
Styrofoam* IB is used by applying plasters based on
cement and with added latex or by dabbling plasters
and/or by applying from inside or from outside on the
surfaces of the roof, walls, and column beams of the
building and later by pasting. The boards are produced
with rugged surfaces to increase the paste power of the
plaster.
HOW ARE THEY APPLIED?
- For the
inner side insulation, the boards are pasted to the
internal face of the wall using cement based pastry
mortar. If the surface is correct for pasting and the
height of the stage is no more than 3 m. the boards may
not have to be fixed using dabbles. If painting is
necessary application of a light layer of satin plaster
is advisable.
- On the
cellar roof where heating is not provided. The Styrofoam
IB boards are pasted onto the roof by using cement based
pastry mortar. The pastry mortar is left drying for a
while and the boards are fixed to the surface at the
back in rows of 6 for every m2 using plastic nail
insulation dabbles.
- In areas of
cellar, which is not, used application of plaster onto
the surfaces of the boards might not be necessary. For
rooms being utilized latex added, cement based ready
prepared plaster are applied directly onto the surface
of the boards. Alkali proof glass fleece plaster rigger
filet is pasted onto the plaster surface (before it is
dried) using steel trowel. And later a few mm. Of
plaster is applied and then left for drying.

ADVANTAGES
- Styrofoam IB thermal resistance
boards can be used for the roof of cellars, bottoms of
porch balconies, and for both columns and beams by
adding for molding as well as later by applying plasters
and eliminates thermal bridges due to its high thermal
resistance qualities.
- The rugged surfaces of the
boards tightly grab the surface where it is pasted to
and also the plaster it is pasted to. In addition,
prevents condensation and becoming moldy and establishes
a healthy living quarter.
- For the inner side insulation,
the boards which are highly vapor diffusion resistant
eliminate the need to use vapor barrier, thus eliminates
costs related to vapor cutter, rigger filet, materials
required for pasting and labor.
- It eliminates the change of
temperature of the wall internal surface to ambient
temperature. Also prevents erosion of the surface layer,
split of the paint and plaster.
- Styrofoam IB thermal resistance
boards do not require renewal work to be carried out
very often and keep their thermal resistance
characteristics for the length of the life of the
building.
- Allows smaller and more
economical use of devices for heating and cooling.
Economizes on maintenance and operational work.
TECHNICAL SPECIFICATIONS FOR
THE MATERIALS OF STYROFOAM IB FOR INSULATION OF WALLS
FROM INSIDE
MATERIALS FOR THERMAL RESISTANCE (TS 11989
COMPATIBLE TSE STANDARDS). For the insulation for
internal wall application the cap less porous
polystyrene - extruded foam XPS boards used must
definitely have armored (binded) surfaces (TSE 825
standards, article number 10.2.1.2.1. of attachment
number 5 of the official gazette numbered and dated
23725 and June 14, 1999). In the case of surfaces being
armored the paste resistance of the boards between paste
plaster and/or plaster cardboards shall not be
sufficient.
RATE
OF THERMAL CONDUCTIVITY (LAMDA). It must not be
larger than 0.031. (For boards with both of the surfaces
being rugged test results carried out at the
laboratories of TSE must definitely be obtained from the
manufacturer).
DENSITY. Must not be at lower than 25 kg/m3 density.
Although under TS 825, article number 10.2.1.2.1 of
attachment number 5 the lower limit of density is given
as 20 kg/m3 for the boards with rugged surfaces we
propose values of 27-28 kg/m3 density to be used to be
able to catch the value of 0.031 W/m.K.
SIZE
DETERMINATION
a) Change of dimensions in the length and the width must
be zero at 60 C and 90 % relative humidity.
b) Change in dimensions must not exceed 2 % under 20-kPa
stresses and at a temperature of 80 C.
c) Must not exceed 2 % under 40-kPa stresses and at a
temperature of 70 C.
Size determination is one of the most important
specifications especially for the wall applications. Due
to differences in temperatures might create size changes
problems on the frontal surfaces. The sizes of the
cells, their placements and their balances in three
directions are very important regarding paste resistance
and size dimension involved.
WATER
ABSORBTION. The water absorption rate for prolonged
periods using full dipping method must not exceed 0.5 %
in volume. Otherwise, the thermal resistance material
absorbs the water of the paste plaster or pasting
plaster it is in contact with and changes the rate of
thermal conductivity (lambda) and the building will
start to consume more energy than anticipated at the
beginning.
THE
PASTING RESISTANCE TO THE PASTE PLASTER. The pasting
resistance of the thermal resistance boards to paste
plaster must be lower than 80 kPa.
THE
PASTING RESISTANCE TO PLASTER CARD BOARDS. The
pasting resistance of thermal resistance boards to
plaster cardboards must not be less than 120 kPa.
WATER
VAPOUR DIFFUSION RESISTANCE. It must be in between
90 and 110. The values must remain at these levels so
that no condensation occurs at the wall cross-sections
and at the same time the building can breathe. However,
a test for condensation at the wall cross sections must
be carried out under any circumstances (please refer to
TS 825 standards given in the official gazette numbered
and dated 23725 and June 14, 1999).
PRESSURE RESISTANCE. Must not be lower than 200 kPa
(TSE 11989, class C2).
RESISTANCE TO FIRE. Must pass the B2 test first,
then must be proven that it has passed B1 class by
applying chimney furnace tests and that it has not been
dripping. Besides the documents obtained from TSE there
must also be certificates granted by the test institutes
in Germany.
CAPILARITY. Must be zero.
SPECIFICATIONS OF THE SURFACE. Both of the surfaces
must only be rugged, for the application of paste
plasters.
LENGTH, WIDTH, DEVIATION FROM THE SET SQUARE, SURFACE
PLAIN, THICKNESS. Must be in conformity of TS 11989.
SIDE
PROFILES. The long sides being tongued would prevent
the work of heat bridges.
