1.Core Raw Materials & Production Process
We ISOKING products use top-grade basalt for our rock wool boards, and here’s the thing—this stuff has a crazy high melting point and built-in fire resistance. That’s not optional, by the way—it’s what makes the insulation actually perform like it should.
Our production process isn’t some fancy new experiment, either. It’s a workflow we’ve messed with and nailed over the years. First, we crush the raw basalt, melt it at insane temperatures, then spin it into fine fibers using centrifugal force. Toss in some eco-friendly binders after that, shape the fibers into boards, and cure ’em at just the right temp to lock in strength and durability.
And we don’t cut corners at the end, period. Every single batch goes through strict quality checks before it leaves our factory. We do this so every board you get works exactly how it’s supposed to—no exceptions, no excuses.

2.Shipping & Packaging
Every batch of our rock wool gets wrapped in heavy-duty moisture-proof film first. Then we stack it on reinforced wooden pallets and strap ’em down tight—like, really tight. That way, nothing gets damp, crushed, or banged up, no matter how rough the sea trip is.
For sea freight? We only work with logistics guys we’ve known and trusted for years. We book 40HQ containers because they fit the most stuff—means your per-unit shipping costs go down. And we track every shipment nonstop, from the second we load pallets at our factory right up to when they hit your port. We’ll shoot you updates the whole time, too. Oh, and we handle all the shipping paperwork—so customs clearance is smooth sailing, no extra hassle for you whatsoever.
3.Installation Tips
Here’s a more conversational, expert-like version that sounds like you’re sharing hands-on tips:
Always make sure you’re working in a well-ventilated spot, and don’t skip the dust mask and gloves. Rock wool fibers can irritate your skin and lungs if you’re not careful—trust me, it’s a small step that saves a lot of hassle later.
Use a sharp utility knife or a proper insulation cutter to trim the boards. Dull blades leave rough edges, which makes sealing gaps a nightmare and kills the insulation performance. You want each piece to fit tight against the surface, then seal every joint with matching tape or sealant—no air gaps allowed, or you’re wasting your time.And don’t even think about installing these boards when it’s wet out. Moisture gets trapped inside fast, and it’ll ruin the material over time. If they do get damp by accident, let them dry out completely before you put them up—no shortcuts here.
