Описание: This is the story of the "stone sweater" for houses – an industry worth over $4 billion in the US alone! 🏠 We're diving into the secrets of how cold, heavy volcanic rock becomes a light, fluffy insulation.

Here’s a completely new look at the manufacturing secrets: 👇
The recipe starts with basalt rock and metallurgical slag – a byproduct from steel mills given a second life.
In a cupola furnace, this stone mix is melted into a white-hot liquid mass hotter than volcanic lava!
The molten stone is spun into a cloud of super-fine fibers, thinner than a human hair, just like cotton candy.
This fluffy mat is then "baked" in a giant furnace, where a special resin polymerizes and glues the fibers together.
Did you know modern mineral wool is made from up to *90% recycled materials*? ♻️ It's a triumph of the circular economy!

Get ready to see how a simple stone becomes a fireproof, sound-absorbing shield for our homes!
