Most people think of cork as something used for wine stoppers or bulletin boards. But here's the twist — ground cork can actually be used as a sustainable building material. Even when finely milled, cork dust is featherlight and still offers excellent insulating properties, without adding extra weight to your construction.

WHAT EXACTLY IS CORK DUST?

Cork dust is an ultra-fine grade of cork granulate. It's dry, soft, and visually resembles flour or sand, boasting a light tan hue naturally found in cork bark.

WHAT ARE THE USES OF CORK DUST?

Its versatility makes it useful across a wide range of industries:

Construction: Mixed into plasters or renders to boost thermal and acoustic insulation. Also used as a filler or in lightweight concrete blends.
Fishing: An essential ingredient in pop-up boilies for carp fishing — enhances buoyancy and improves bait performance.
Pyrotechnics: Because it's flammable, it's included in sparkler formulas and special effect compounds.
Glassmaking: Applied as a separating agent in molds — leaves no traces or contaminants behind.
Battery Production: Used as a thermal barrier between molds and molten metals.
3D Printing: Incorporated into eco-friendly filament blends for added structure and texture.
Paints & Decorative Plasters: Offers insulation and gives a textured, earthy finish when added to surface coatings.
Model Building: Perfect for terrain work in architectural, rail, or holiday nativity models.
Custom Composites: Combine it with glue or resin for DIY material projects.

IS CORK DUST ENVIRONMENTALLY FRIENDLY?

Yes — cork is a fully renewable resource. Harvesting it doesn’t damage the tree; the bark regrows naturally, and cork oaks can thrive for centuries.

HOW SHOULD IT BE STORED?

For best results, store cork dust in a dry, sealed container and keep it out of direct sunlight. This helps preserve its texture and performance over time.

DOES IT LOSE ITS INSULATING PROPERTIES WHEN MIXED?

Not at all. It stays lightweight and insulative even when combined with other components. The only change is that it forms a more compact mass depending on the mix.

CAN IT BE USED AS BIOMASS?

Yes, it can. Cork dust is a clean-burning biomass option that aligns perfectly with sustainable and circular economy practices.

HOW DOES IT DIFFER FROM CORK GRANULATE?

Size is the key difference. Cork dust has a fine, powder-like consistency, whereas cork granules are chunkier — some as large as couscous or even cork chips.

WHAT IS ITS DENSITY?

Density varies based on grain size. For particles under 0.25 mm, it's typically 90–110 kg/m³. For coarser grains between 0.2–0.5 mm, expect 60–80 kg/m³.

HOW IS CORK DUST PRODUCED?

The production involves mechanically grinding clean cork pieces until they reach a fine consistency. Then, the material is sieved to achieve a uniform particle size.

Cork boards and rolls are a go-to for many uses — but when precision matters and every crevice counts, you need something more adaptable. Cork dust brings cork down to a micro level: soft, loose, and eco-conscious. Synthetic options don’t come close — they're bulkier, less flexible, and let’s face it, unnatural.

#1 SUPER LIGHTWEIGHT & NON-REACTIVE

Cork dust is impressively lightweight — that’s thanks to its sponge-like makeup of countless tiny air-filled cells. You get volume without the weight, which makes it incredibly easy to handle, pour, and apply wherever it’s needed.

Another plus? Cork dust is chemically neutral. It won’t react with adhesives, solvents, or gases — making it perfect for use with glues, resins, and plasters. It also resists UV damage and natural decay, which is a major win for outdoor use.

#2 ONE PRODUCT, COUNTLESS USES

Cork dust fits into all kinds of industries — from construction materials like thermal plaster to acoustic insulation and creative hobby projects. It plays a key role in boosting both energy efficiency and sound control in coatings and wall finishes.

Its real power lies in its versatility. Flexible and compressible, cork dust adapts easily to specific design needs. Whether you’re building scale models, crafting unique decor, or working on functional pieces — it blends effortlessly with other mediums.

#3 SAFE TO TOUCH, SAFE TO USE

Cork dust is hypoallergenic and safe to handle. It won’t cause skin irritation or allergic reactions, making it a smart choice for sensitive environments like schools, studios, or home workshops.

And we’ve got the credentials to back that up. Our cork granules are certified by the National Institute of Public Health in Poland (PZH) — a trusted authority. This certificate confirms our material is health-safe and meets international safety benchmarks. In fact, we’re currently the only supplier in Poland offering this level of verified cork granulate.

#4 EARTH-FRIENDLY FROM START TO FINISH

Natural cork is a completely renewable and sustainable resource. Harvested from the bark of the cork oak tree — without cutting it down — the process allows the bark to regenerate, maintaining the ecosystem’s natural balance.

Our cork dust is often created by repurposing cork waste — like wine stoppers, panels, or sheets. It’s a great example of circular economy in action: recycle, repurpose, reuse. It’s a smart, sustainable choice for businesses and creators alike.
