WeatherPro-S is a flat external
grade high quality building
board for heavy-duty commercial
and industrial use, such as
train station or airport. The
board is made of non-combustible
raw materials and has undergone
an extremely high pressure pressing
process. thus, making WeatherPro-S
inborn with good strength and
good resistance to impact. It
is designed for use in external
applications or internal applications
where high resistance to impact
damage and weather resistance
is required. It is economical
and durable when comparing with
traditional plywood, MDF board
or chip board for similar applications.
The board is manufactured to
ISO 9001 quality management
system and has obtained the
Green Label Award issued by
National Environmental Protection
Bureau.

WeatherPro-S is a highly
compressed high density
calcium silicate board
reinforced with selected
fibres. It is formulated
without asbestos or
any other inorganic
fibre. Its manufacturing
process is pollution-free
and hence the product
is a green construction
material. WeatherPro-S
composes of calcium
silicate matrix, reinforced
fibres and synthetic
cement silicate binder.
It has undergone a high
pressure pressing process
together with an autoclave
process where steam
under high pressure
is injected for curing.
The synthetic cement
silicate binder provides
exceptional dimensional
stability and an unrivalled
resistance to movement
due to effects of moisture
or heat. The board will
not rot or support fungal
growth and is unaffected
by sunlight and steam.
The board does not contain
any soluble ingredients
or free alkali which
could be dissolved out
by moisture or condensation
causing unsightly marks.
The board is watertight
and fully weather resistance
and its performance
will not degrade in
its lifetime when properly
installed, WeatherPro-S
is light grey in color
and has smooth surface
on both sides. It can
be left undecorated
or can be easily decorated
with paints or other
external applied finish,
alkali-resisting primer
are not required. WeatherPro-S
can be used as furring
or left-in formwork
for reinforced concrete
construction or as a
permanent lining board
for metal cladding.
The unique characteristic
of high density autoclaved
calcium silicate means
that WeatherPro-S is
by itself moisture tolerant,
it is tough, durable
and resistance to impact
damage and is commonly
used in areas where
permanent damp or high
humidity are anticipated
such as washrooms, kitchens,
food factory or external
locations.
