It is said that across the world, the building sector consumes too many resources and produces too much waste. Twenty five percent of the world’s water and 40 percent of its resources are used by buildings, while creating one-third of all waste and 40 percent of global carbon emissions. We all have a part to play in protecting the environment and our planet...isn’t it?
By selecting sustainable and circular construction materials, we can save energy and resources, and limit waste.
One such construction material that opens up this possibility is Stone wool or rockwool, which is the most widely used insulation material in Europe because they are fire-safe, durable, reusable, sound-absorbing as well as moisture-resistant.
Even in India it is widely used in refineries, power plants, airports, commercial buildings, industries and factories etc.
If you are listening to us from an indoor location, then it is possible that you have stonewool / rockwool insulation around you behind those walls and ceiling.
So how are rockwool’s made?
Basalt rock, dolomite and slag are heated to very high temperatures using coke.
Molten mixture is passed through very high speed spinners to form fine fibers which are impregnated with thermosetting resin (Binder)
Fibers are converted to LRB, Slabs, Building Roll of various density, thickness and facing after passing through the curing oven.
Now that you understand the basic use of rockwool, think about this, in developing nations around the world infrastructure projects are crucial to its development. Due to this old constructions may be demolished for new, or up for renovation. Be it any, all are going to make use of rockwool at some point of time.
Tune into the episode to find out how this Danish organization ROCKWOOL is doing things differently. Yeah...don’t be confused, their name is derived from the product they sell.
