Multipurpose
Multipurpose is a cellulose fibre reinforced cement building board. Being an autoclaved composite material, it is tough and flexible making it the ideal choice for internal and external building requirements.

Multipurpose enables rapid installation and is ideal for internal dry wall systems, ceilings soffits, floors and roofs. Multipurpose may also be used as an external sheathing board where the board is to be exposed to the weather for a longer period prior to the outer cladding system being installed.

Multipurpose is not recommended as a carrier board for render, please refer to Renderflex.

 

 

 

 


Technical Data

Basic Composition - Multipurpose is made from specially treated high grade cellulose fibre, Portland cement, refined sand and water.

General Properties - Multipurpose with a stable crystalline structure is highly resistant to water penetration, humidity, rot, insects, termites, vermin and is fire rated class O.

Machine-ability - Multipurpose can be cut, drilled, nailed and worked in a similar fashion to timber and chipboard with standard wood working tools, but offers a much longer performance life.

Applications - Multipurpose can be used in an extensive range of applications both internally and externally (semi exposed). It offers the highest levels of weather-ability of all of the RCM boards (exc Supertech) and is can be used for soffits, behind cladding, floors, partitions and various OEM applications.

Maintenance - Virtually maintenance free, so cost effective.

Health & Safety - Appropriate health and safety precautions must be adhered to when working with this product (see lifting and handling section). Suitability: Floors | Laminate | Ceilings | Partitions | Soffits | Sheathing Board | Wet Areas
