The sustainability of fibre cement
Kalsi is the brand of fibre cement boards and planks under Marley Building Systems in South Africa.
Three of the Kalsi product categories include KalsiCeiling, KalsiCladding and KalsiPlanks. Each are successfully used in residential, commercial and industrial building applications, particularly because of the many advantages of fibre cement over brick, block and wood.
Kalsi products are manufactured from a precise combination of cement, silica and cellulose. They are then cured and stabilised in an autoclave (a special process involving steam, high temperatures and pressure) to ensure optimum dimensional stability and mechanical resistance. As a result, Kalsi fibre cement boards and planks are durable and highly resistant to most environmental conditions – which is why they are the best alternative to wood, concrete and masonry construction materials.
Kalsi is extensively used in dry construction – a building technology that uses fibre cement boards installed over metal or timber sub-construction. Dry construction is often used to build exterior walls (cladding), interior walls (partitions), ceilings and other applications. It is a more economical and environmentally friendly form of building that is taking precedence worldwide.
In addition to being recyclable and sustainable, Kalsi fibre cement is also cost-effective, strong, durable, flexible in design and adaptable.
