WeatherPlank Siding products are made of autoclaved fibre cement reinforced calcium silicate boards that are 100% free from asbestos or sepiolite. Since WeatherPlank is laminated of specially formulated calcium silicate mixtures and selected fibres to form the designated thickness, unlike other siding boards made of vinyl or timber materials, maintenance cost of WeatherPlank is low. It is robust, impact resistant, moisture resistant and non-combustible. It is designed for use in direct weathering applications when used in conjunction with external grade textured finishes and other surface coatings or internal decorated applications. It can hold paint finishes 3-4 times longer than other siding board materials do. It has high water vapour permeability which helps eliminate condensation or water trapped behind the boards. Available products include WeatherPlank Siding, WeatherTrim and WeatherPlank Panel. WeatherPlank Siding Products are ISO9001:2000 (Certificate of Conformity of Quality Management System Certification) and ISO14001:1996 (Environmental Management System Certificate) certified and have obtained Green Product Label Award issued by National Environment Protection Bureau.
WeatherPlank is made of WeatherPro.-L fibre cement reinforced calcium silicate board, which is produced from a mixture of cement, silica, special cellulose fibres and selected fillers to impart durability, toughness and moisture resistance. It 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. WeatherPlank will not rot or support fungal growth and is unaffected by sunlight and steam. It does not contain any soluble ingredients or free alkali which could be dissolved by moisture or condensation causing unsightly marks. If exposed to moisture, WeatherPlank will completely recover on drying out naturally, with no permanent loss of strength. It 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.
WeatherPlank is easy to cut on site with standard wood working tools. Where seamless finishes are required, it can be finished with thin coat polymeric renders or other surface coatings to give a seamless finish. Standard WeatherPlank is off-white in colour and has a high quality embossed wood-like, wood grain smooth or traditional smooth surface textures.
