(fly ash) * manufacturing process is 100% recyclable - Cut/use. * reduces emission of co2. * uses one third raw material from mother earth, due to low density very low environmental impact. * good thermal insulation -lower energy cost (up to 26% power savings) * good sound insulation -low noise Other benefits : * requires very less water in construction- Practically dry construction. * very light weight -reduces the structural load. * provides more carpet area in every floor/room. * fire-rating up to 4 hrs.
