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 the use of 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 ISO14001 environmental management system, and has obtained the Green Product Label Award issued by National Environment Protection Bureau.

WeatherPro.-S is a highly compressed high density calcium silicate board reinforced with selected fibres (alias named as compressed high density fibre cement board in North America) . It is formulated without asbestos, sepiolite, formaldehyde or 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 ferry and train stations, machine rooms, food factories or external locations.

WeatherPro.-S is used in a wide range of external and general purposes for building applications in domestic, commercial, industrial and agricultural including:
 Impact resistant fence walls
 Heavy duty wall fascia / cladding
 Floor decking
 Encasement to steelworks
 Fascias and shop fronts
 Verge under cloaking
 Claddings in tunnel
 Service enclosures
 Noise barriers at highway
 Left-in formworks
