Regranulated cork 3-4mm - 10kg

It’s simply natural cork that’s been ground into small particles. They’re lightweight and adaptable. Thanks to this form, cork becomes way more versatile—you can pour it or fill in tricky gaps. Basically, it does what sheets just can’t.

Granulated cork has loads of uses in all sorts of fields:

• Construction and industry: works great as an additive in lightweight concrete, thermal plaster mixes, bonding composites, or even foundations.
• Insulation: perfect for stuffing wall cavities to boost thermal performance.
• Composite structures: used as a lightweight, flexible core in, for example, cabins and specialist vehicle interiors.
• Furniture production: an eco-conscious stuffing for pouffes, cushions, or chairs.
• Footwear: a component in crafting soles and inner shoe linings.
• Gardening: mixed into soil, it boosts structure and air flow.
• Crafts and models: looks just like gravel or crushed rock—ideal for nativity sets, dioramas, or as theatre props that mimic sand.
• Absorbent uses: handy for mopping up oil spills.

Density depends on the grain size (also called the fraction):

• 0.5 – 1.0 mm: around 140–150 kg/m³.
• 1 – 2 mm: roughly 100–110 kg/m³.
• 2 – 3 mm: between 120–130 kg/m³.
• 3 – 4 mm: approximately 110–120 kg/m³.
• 4 – 5 mm: around 120–130 kg/m³.

Yes, cork It’s made from the outer bark of cork oak trees—a renewable material that’s harvested without harming or felling the tree. It’s 100% biodegradable and environmentally safe.

It all starts with the bark of cork oak trees. The trees themselves aren’t harmed—the bark is carefully peeled off every 9 to 12 years, then left to dry and cleaned thoroughly. Once prepped, it’s processed through machines that crush it into granules. This results in different grain sizes, from powder-fine to chunky bits.

Nope, ground cork keeps all the benefits—thermal and sound insulation, water resistance, and flexibility.

Turning cork into granules just gives you more ways to use it: pour it into small spaces, mould it where needed, or insulate spots that rolls or panels can’t reach. It’s simply more versatile—light, flexible, and a breeze to use in tricky areas.

Yes—it’s a very good insulator for both heat and noise. That’s all thanks to its natural structure, made up of millions of tiny air-filled cells.

Unlike synthetic stuff like mineral wool or foam, cork doesn’t need any chemical tweaks. It’s light, breathable, and doesn’t make a mess. You get all the usual insulation perks, plus it’s eco-friendly, non-toxic, and gentle on the planet—and on you.

We sure do! Our range also includes:

• Cork dust – superfine texture, almost like powder or flour.
• Cork nuggets – bigger pieces, great for when you need something loose but a bit more substantial.

Store them somewhere cool and airy—like a garage, pantry, or cellar. Avoid places that are hot or in direct sunlight, and don’t keep them near heaters. A sealed container will help keep the granules fresh and ready for use.
