Cork dust

Not every application requires natural cork in sheet or roll form. Perhaps this time, you need insulation that fits easily into gaps? Something loose and ultra-light, right? Cork dust is natural cork in its "micro" form – the finest cork granulate. Light, loose, and flexible!

You probably have a few questions, so we’ve prepared the answers!

WHAT IS CORK DUST?

Cork dust is finely ground natural cork, similar in texture to flour or sand. It is light, loose, and dry. It is produced by grinding natural cork, which has been carefully cleaned and dried beforehand.

WHAT IS CORK DUST USED FOR?

Cork dust is used in various industries, including:

Construction – As an additive to plasters, enhancing their thermal and sound insulation properties. It is also used for insulation fillings in building structures and as a component of lightweight concrete.
Fishing – In the production of pop-up balls for carp fishing, making them more effective at attracting fish.
The production of fireworks and pyrotechnic effects.
Glassworks as a separator for moulds.
Battery production.
The production of paints and plasters.
3D printing as an additive to filaments.
Railway, architectural, and historical modelling as a sand imitation.

IS NATURAL CORK ECO-FRIENDLY?

Yes, it is a fully eco-friendly material. It is biodegradable, free from harmful substances, and can be reused.

DOES CORK CAUSE ALLERGIES?

No, natural cork is hypoallergenic and has antibacterial properties, preventing the growth of mould and fungi. However, during processing, fine dust particles may become airborne, so it is recommended to wear a mask to avoid inhaling them.

Cork sheets and rolls are practical, but what if you need something for fine gaps or lightweight filling? That’s where cork dust comes in. It offers more versatility than traditional cork— in construction, it works as an additive to plasters, enhancing thermal and sound insulation properties. It’s also an excellent lightweight insulation filler for structures and a key component of lightweight concrete. Less building mass, more effective insulation – that’s how it works.

But cork dust isn't just for construction. If you're into fishing, you know that a good bait can make all the difference. Adding cork dust to pop-ups makes them lighter and ensures they float at just the right level – not too high, not too low. This makes them more visible to fish, increasing the chances of a successful catch.

Cork dust comes from the bark of the cork oak tree, but don’t worry – the trees aren’t cut down. The bark regenerates, and the tree continues doing its job: absorbing CO₂, producing oxygen, and living for up to 200 years. It’s a 100% natural, renewable material with no hidden downsides.
