WeatherPro.-L is an autoclaved fibre cement reinforced calcium silicate board (alias as fibre cement board in North America) that is 100% free from asbestos, sepiolite, inorganic fibres or formaldehyde. WeatherPro.-L is specially designed for use in applications where impact resistance is required in a high humid environment. It is a versatile, economic building board substitute of plywood, cement-bonded particle board, gypsum boards or magnesium boards. It is light weight, robust and moisture resistant. It will not warp, swell or decay in wet area. WeatherPro.-L is an excellent substrate for ceramic tiles. It can be applied in direct weathering applications when used in conjunction with external grade paint finishes. 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.-L is produced from a mixture of cement, ground sand, special cellulose fibres and selected fillers to impart durability, toughness and moisture resistance. The board is then cured by an autoclaving process whereby the ingredients are reacted together under the effects of super-heated steam and high pressure. 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 by moisture or condensation and causing unsightly marks. If exposed to moisture, the board will completely recover on drying out, with no permanent loss of strength. The board will not degrade with time and within normal applications, the life of the product is limited only by the durability of the supporting structure and materials used in fastening. WeatherPro.-L is natural off white in colour and has a smooth finish on one side and a slightly textured reverse.


WeatherPro.-L can be used in a wide variety of building applications because of its easy working, fixing and decorating characteristics. Typical applications include:
 Roofing substrate panels
 Impact and acoustic wall & ceiling panels
 Internal and external walling linings
 Bathroom and shower partitions
 Kitchen and Laundries
 Ceramic tiles backing boards
 Domestic decking applications such as balconies, verandahs and pool surrounds
 Bus bar or electrical protection
 Cooling tower linings
 Facades, planking and shingles
 Parapet linings
 Floor tiles / composite floor panels
 Sanitary cubicles
 Decorative and moisture resistance ceiling
