Anti Vibration Machine Foundation Slabs,
Insulation Cork Board and Expansion Joint Filler
Anti Vibration Cork Slab is produced with granulated Cork
Particles securely bound together with a synthetic resin of an
insoluble nature.
Main Application
All machines or generators, compressor should be isolated in
such a way so as to reduce and if possible eliminate the
transmission of vibrations and consequent noise to the building
wherein it is installed and the neighbouring buildings.
ZEBRA Isocork Slab
Can satisfactorily resolve problem of that nature and used with
good results in the Anti-Vibratic isolation of foundation of
heavy machinery reducing very considerably its transmission to
the structure of the building.

It is, therefore, an ideal material for thermal insulation or
cooling chambers, to improve noise levels or to provide
vibration insulation for running machinery. Insulation Corkboard
is an excellent thermal and acoustical insulation material,
besides being imputrescible, resistant to compression and
flexural efforts, and of great dimensional stability.
Insulation Corkboard the pure expanded cork
Insulation Corkboard is made from autoclave expanded cork
particles which are then bonded together with their own resin.
Depending on the end use in mind - thermal insulation,
acoustical insulation or vibration control - the specific
gravities of the material will differ.
Energy Savings
Whether it is used in ceiling, walls or flooring insulation,
Insulation Corkboard will be the ideal material due to its
durability and ease of installation, and it is especially
recommended for installation in cooling chambers.
Noise Control
The insulation of interior partition walls with insulation
Corkboard will drastically reduce airborne noise propagation,
creating a pleasant environment. You'll even stop hearing your
neighbour's TV set.
Vibration Control with Insulation Corkboard
All running machinery of a certain size will generate vibrations
that will transmit down to the floor. Such machinery should
always be mounted on bearing pads and isolated from the other
structural elements. Boards of high density Insulation Corkboard
will give excellent results in this type of isolation. Vibration
related cracks will be a thing of the past.
Regranulated Cork
When applied loose, as a filling material in wall interiors
mixed with concrete (lightweight concrete), or as a soil
levelling material, Regranulated Cork can be put to many uses in
the construction industry.
SPECIFICATION OF EXPANSION CORK JOINT BOARD
Expansion Cork Joint Board is a perfect jointing material which
follws the movements of other materials. It can expand and be
compressed time after time without changing its material
properties in any way.
Expansion Cork Joint Board is used to absorb thermal movements
in concrete structures - airport runways, motorways, bridges,
dams and the like.
Cork is such a good jointing material because of its unique
design, created by Mother Nature herself. The material consists
of fully sealed cells made of cellulose and resin and filled
with air.
Expansion Cork Joint Board is used in many different types of
structures - airport runways, motorways, bridges, buildings and
so on. Expansion Cork Joint Board functions as a horizontal or
vertical building joint between concrete elements, brick and
building stone. Wherever you need a joint that can allow for
changes in the volume of other materials - as a result of
thermal movements - Expansion Cork Joint Board is the answer, no
matter whether it acts as a jointing material or protects
concrete elements from fracture and cracking.
Cork is a particularly fine jointing material in structures
which require an even surface, such as airport runways. The
reason is that Expansion Cork Joint Board, which is subject to
pressure, never compensates for a compression in one direction
by expanding in another direction. The walls of the cork cells
condense and the cork then regains its original volume once the
pressure is released. Another benefit is its unique ability to
withstand extremely high pressure for short and long periods
alike. Expansion Cork Joint Board can be compressed time and
time again without losing its properties or being destroyed.
