These panels made of polystyrene and steel mesh could replace bricks
The Building Material and Technology Promotion Council floated tenders for alternative construction technology in 2010 and Ritman Group was among the companies short-listed. What the company offered as an alternative was ‘Structural Insulated Panel System’.
The panels are made of high technology polystyrene (thermocol) and steel mesh with high strength RCC sprayed on either side. Parag Majmudar, chairman and managing director of Ritman Group of Companies, who was in Coimbatore recently for BuildMat 2013 explained to The Hindu Habitat :
The modular panels can be used with normal construction frame. The thermocol is 60 mm, 80 mm, or 120 mm thick. Italian technology that has been in use for nearly 30 years and adopted in about 60 countries, these modules make buildings energy-efficient and provide thermal insulation. Compared to regular buildings, it gives at least 15 per cent saving on the cost, he says.
The product decreases the load on the structure and hence can be used in multi-storeyed buildings. With the technical expertise of a Malaysian partner, the Ritman Group opened a factory in West Bengal recently with a capacity to make 1,000 sq.mt of modules in one shift. It now has orders from the Central Government and is talking to a couple of State Governments to work on their project as well. A mobile unit can be set up if there are orders for atleast five lakh sq.ft. The investment for a plant is about Rs.15 crore
