Magnesia drywalls: better than bricks
This defies international trends wherein brick or block walls have been jettisoned long ago for the modern and superior magnesia drywalls. If the international ratio of drywalls to brickwalls is 80:20, in India it is reversed.
‘Drywalls’, are walls constructed without the use of water at site, usually a metal framework as skeleton and building boards mechanically fastened on either side.
The industry did experiment with drywalls in the last fifty years by first switching from brick walls to internal partitions made of timber frame and wood-based panels. In the 1980s gypsum board and metal frame became the non-wood option, followed by calcium silicate and grey cement boards. One possible reason why drywalls could not make much headway was because none of the drywall options could substitute brick walls.
Now magnesia drywalls have entered the market. These have been in vogue in several countries: USA, Canada, UK, South Africa, Australia, Russia, China. In fact, China has been the world’s largest manufacturer, domestic consumer and exporter, by virtue of the fact that it has the world’s largest deposits of magnesite. They have been employed in these countries for both external walls and internal partitions. It is, however, novel to India.
Magnesia drywalls mimic a brick or block wall. They are strong and impact-resistant. They do not get spoilt in damp or wet conditions and so can be
