 Styroboard
is an excellent insulating material that has secured a firm
position in the insulation sector. It is a polystyrene rigid
foam for up-to-date energy-saving and economical construction.
Buildings today and in the future are characterized substantially
by requirements for energy saving, noise and environmental
protection. Virtually all industrialized countries today have
statutory minimum requirements for the constructional thermal
insulation of heated
and air-conditioned buildings. This is due to the fact that,
in tropical area the energy lost in summer air conditioning
of  buildings
is a significant factor. This is comparable to the energy
used for heating in winter for cold countries.
Such material give the owner of a building under construction
considerable cost/benefit advantages with reduced risk of
technical errors in the execution of work.
Styroboard
Advantages in Construction:
Extremely
low density combined with good load resistance imposing less
weight on structure and easy to handle.
Excellent
thermal insulation as styroboard
is about 40 times better than usual concrete.
Good
impact and sound insulation. It can absorb direct shocks and
sound waves.
Durable
and reliable as it is unaffected by:
- Water, moisture, humidity
- Alkalis and moist acids
- Harmful microorganisms
Comes
with flame retarding agent. It is more difficult to ignite
with considerably reduced rate of flame spread.
Good
engineering knowledge leading to
- Wide scope of application
- Economical construction material and methods
Environmentally
safe and have no deleterious effects on Human health.
Roof
construction with Styroboard
From the viewpoint of construction,
the roof is subjected to most aggressive environment. Heat
and storms, dryness and wetness, act from outside conditions,
while internal relative humidity acts from inside. Roof designs
and materials, as protective element; have to be adapted to
these conditions.
Whether a flat roof or a pitched roof, whether someone's home
or an office building, on factories, workshops or warehouses,
whether a roof garden or an underground garage stryoboard
foamed plastics play a significant part in this connection,
because they have outstanding insulation and offer economical
answers as insulating systems.
Flat roof insulation
is an important field of application for styroboard
foamed plastics. The insulating material may be laid
loosely with ballast (e.g. gravel). fixed by hot or cold adhesive
or mechanically fastened with special dowels to the underlying
surface.
Pitched roof space in many countries,
is increasingly being developed as additional area for living,
storage, play or hobby purposes.
Adequate thermal insulation of the roof
surface, as the area bounding indoor from outdoor, must be
provided. styroboard rigid
foams is suitable for use as insulation in pitched roofs in
the form of filler insulating boards laid between rafters.
Such insulation systems make economical construction work
possible and offer lasting thermal protection. For existing
structure, boards are used with underlying vapor barrier laid
on the existing roof battens. The tiles are then re-laid on
cross battens fixed through insulating units.
Floors
Styroboard board forms an excellent
resilient layer for floating floors, which greatly lessens
the transmission of impact and noise. It may also be used
to provide the thermal insulation required below the heating
elements of underneath floor heating systems.
Wall
construction with styroboard
A wall is both a load bearing and a protective building unit.
It protects the surrounded space against the effects of temperature
and whether and against noise.
Nowadays,
the thermal insulation function is becoming an important factor.
The styroboard
insulating layer can
be applied easily on the outside of the load bearing wall
and weather-protected either by a reinforced special plaster
or by a ventilated facing layer.
A method widely used is by fixing external insulating boards
to the wall with bonding mortar and subsequently covered with
a fabric reinforced dispersion plaster. The reinforcement
of the plaster layer with alkali resistant glass fiber sheets
is necessary to absorb the material and temperature dependent
stresses in the plaster layer occurring on the insulated facade
as the result of temperature fluctuations.
Chemical
and physical properties
styroboard
is expanded polystyrene containing a blowing
agent. It is formed by polymerization of monostyrene, with
the addition of pentane.
Cellular polystyrene consists of an
assembly of myriad's of tiny, air-filled cells. Most of the
physical properties of cellular polystyrene
depend on the density of the material.
It should be noted that expanded polystyrene
is most likely to be affected by organic solvents or plasticizers.
Adhesives and paints must be chosen with care, and direct
contact with plasticized PVC should be avoided.
