I was looking at the latest industry data: the Chinese mineral wool market is projected to hit 200 billion RMB by 2025. Honestly? Looking at the frontline, that number feels low—maybe it’s missing a zero.
It’s easy to see why. Mineral wool is made from melted rock; its fire performance is solid, and the price is dirt cheap. But as someone who has spent years in the insulation trenches, I see a much darker side to this "growth."
The "Banned" List is GrowingHave you noticed? In industries where hygiene and long-term safety are non-negotiable—like food plants, specialized shipbuilding, and eco-certified buildings—mineral wool is being phased out or outright banned.
The Price of "Cheap"The biggest problem with mineral wool is that it’s only "cheap" the second you buy it. After that, the costs start compounding:
The Health Debt: We all know it. It’s itchy, it’s messy, and once those fibers are in your lungs, they stay there. In an era of strict ESG and labor safety, can your plant afford that liability?
The "Wet Sponge" Effect: Mineral wool loves water. On a hot tank, it becomes a reservoir, leading to hidden Corrosion Under Insulation (CUI). You think you’re saving money on material, but you’re actually rotting your multi-million dollar equipment from the inside out.
The Solid Waste Trap: You buy it for a few hundred dollars per cubic meter, but a few years later, when it sags and loses efficiency, you’ll pay double that just to get rid of it. Illegal burying will get you fined into oblivion, and legitimate disposal is a logistical nightmare.
The Vicious Cycle of MaintenanceIn a modern factory, "Safety First" means you can't just swap insulation while the machines are humming. You have to shut down. The time lost during a mineral wool replacement cycle is often worth more than the insulation itself.
My Take:The industry is stuck. Production is still rising because the low-end market has a massive appetite. But the "invisible hand" of environmental costs and new material technology is already pushing the lever.
We aren't calling for an overnight ban, but we are calling for a rational, orderly transition. If you’re tired of the "buy-replace-dispose" cycle, it’s time to stop looking at the price per bag and start looking at the cost per decade.
