Cork granules (granulated cork) 0,5 - 1mm - 3kg

It’s natural cork in a crushed form. The grains are light brown, earthy in colour, and have a porous texture. They’re adaptable, durable, and dust-free. This form of natural cork offers far greater versatility—you can pour it, fill gaps, and shape it as needed. In other words, you can do things that simply aren’t possible with sheets or rolls.

Granulated cork has a wide range of applications across various industries:

• Construction and industry: as an additive for lightweight concrete, thermal insulating plasters, adhesive composites, or even foundations.
• Insulation: ideal for filling cavity walls, improving their insulating properties.
• Reinforced composite cores: used as a lightweight, flexible core in, for example, cabins and specialist vehicle interiors.
• Furniture-making: as an eco-friendly filling for pouffes and armchairs.
• Footwear: used to make soles and insoles.
• Sports and surfaces: as a filler for punching bags, balls, shooting rests, and shuttlecocks. It’s also used as an eco-friendly infill for sports surfaces, cushioned playground bases, and fake beach settings.
• Horticulture: when mixed into soil, it improves aeration and structure.
• Modelling and crafts: mimics gravel, rocks, or crushed stone – ideal for models, nativity scenes, and decorations. Also used as a lightweight sand imitation in theatre and opera scenery.
• Terrarium keeping: a natural, safe substrate for terrariums.
• Spill clean-up: often used for cleaning up oil spills.

Yes, it holds an official hygiene certificate issued by the National Institute of Public Health in Poland (PZH). This confirms that the granules are completely safe for skin contact: they don’t cause allergies, irritation, or any adverse reactions. If you’re looking for a material with proven quality—this is it. We are currently the only company in Poland offering cork granules with such certification.

The density of cork granules depends on the fraction (grain size):

• 0,5 – 1,0 mm: 140–150 kg/m³.
• 1 – 2 mm: 100–110 kg/m³.
• 2 – 3 mm: 120–130 kg/m³.
• 3 – 4 mm: 110–120 kg/m³.
• 4 – 5 mm: 120–130 kg/m³.

Yes, it comes from the natural bark of the cork oak—a renewable raw material harvested without cutting down the trees. It’s completely harmless to the environment, as it decomposes on its own. Contains no plastics or chemicals, so it leaves no pollution behind. It naturally returns to the earth.

It’s produced from the bark of the cork oak tree. The tree itself is not cut down—its bark is carefully stripped every 9 to 12 years, then dried and cleaned. After that, the material is fed into machines that mechanically crush it. This process yields different fractions, ranging from very fine dust to larger cork pieces.

No, cork granules are simply a different form of natural cork, and they retain all the same insulating properties—thermal, acoustic, moisture resistance, and adaptability.

By grinding cork, you gain new possibilities: you can pour it, shape it, fill gaps, or use it in places where sheets or rolls wouldn’t work. Granules offer more flexibility—they adapt to shape, are lighter, and easier to apply in hard-to-reach areas.

Yes, cork naturally insulates—both heat and sound. This is thanks to its structure: cork is made up of millions of tiny, closed cells filled with air.

Unlike synthetic materials such as polystyrene or mineral wool, cork doesn’t require chemicals or heavy processing. It’s lightweight, durable, breathable, and dust-free. It functions much like other insulators but with the added benefits of being natural, safe, and kind to both your health and the environment.

Yes, we also offer:

• Cork dust – an ultra-fine form, almost like flour.
• Cork nuggets – larger pieces of cork, ideal for situations where a bulkier material is needed but still in a loose form.

It’s best to keep them in a cool, well-ventilated place—a garage, cellar, or pantry will do just fine. What matters is that they’re not stored next to a heater, in a hot room, or in direct sunlight. Make sure to keep the granules in a sealed container.

Yes, absolutely. It’s a soft and pleasant-to-walk-on material that cushions your steps well. Unlike stones, gravel, or concrete, it doesn’t press into your feet, doesn’t heat up quickly, and doesn’t turn into mud after rain.
