Gypsum plasteboards

The last few years have seen a range of meaningful developments in the construction landscape. The influx of technological advancements has helped curate advanced offerings that give several advantages over the traditional processes. 
 
When you build your house or renovate it, it is common to come across people suggesting the use of gypsum plasterboards. Even though not a new finding by any means, it is only in the last few years that it has found increased traction in the construction scenario.
 
Gypsum boards are useful in building lightweight and durable walls. 
 
Even though we are seeing increased use of synthetic gypsum plasterboards, the traditional ones use dehydrated calcium sulfate and convert it into CaSO4.0.5H20 by heating it.
 
Once dehydrated, the resulting product is mixed with several additives and water. It is then placed onto cardboard running on a conveyor belt. It soon takes the shape of a needle-like structure that combines to form what we commonly know as gypsum plasterboards.
