WHAT EXACTLY ARE CORK NUGGETS?

Think of cork nuggets as oversized cork granules. These chunky, irregular pieces come in XXL size, often measuring several centimeters, and bring a rugged, natural texture to any application.

HOW CAN YOU USE CORK PIECES?

  • Construction – Adds lightweight insulation to structures, enhancing soundproofing and thermal efficiency.
  • Manufacturing – Eco-friendly and easy to shape, ideal for technical and industrial solutions.
  • Furniture making – A natural filler that helps create sustainable, lighter furniture designs.
  • Industrial flooring – Helps deliver non-slip, durable surfaces in high-traffic areas.
  • Modeling and set design – Perfect for realistic landscapes, rubble, and props in dioramas or stage productions.
  • Terrariums – Acts as a decorative, animal-safe base for exotic pets.
  • Crafting and DIY – Great for custom art projects, home décor, and creative expression.
  • Children’s activities – A safe and fun material for crafts and educational workshops.
  • Interior design – Stylish filler for vases, bowls, aquariums, and other creative displays.

WHAT IS THE TYPICAL DENSITY OF CORK PIECES?

Density varies based on the size of each piece. Here’s what you can expect:

  • 10–20 mm pieces usually weigh in around 135–145 kg/m³.
  • 10–50 mm pieces generally come in at 130–140 kg/m³.

IS THERE A CERTIFICATE FOR GRANULATED CORK?

Yes, absolutely – our cork products are backed by an official hygiene certificate issued by Poland’s National Institute of Public Health (PZH), ensuring they are safe for skin contact and free from allergens or irritation.

We are proudly the only provider in Poland offering certified cork granules with this level of assurance.

ARE CORK PIECES AN ECO-FRIENDLY CHOICE?

Definitely – cork is 100% natural and biodegradable. Harvested without cutting down trees, cork oak bark regenerates naturally and can be collected for more than 150 years.

Most cork comes from Portugal and Spain, where responsible and sustainable harvesting practices help preserve forests and protect biodiversity.

HOW DO CORK NUGGETS DIFFER FROM REGULAR CORK GRANULES?

The main difference is all about size:

  • Cork nuggets are larger, irregular pieces that make a bold, natural statement.
  • Cork granules are smaller and more uniform, better suited for precise applications.

In short, cork nuggets offer a more rugged, coarse option — ideal when you want a natural look and feel with extra texture.

Cork pieces come in all shapes and sizes, but they share a few core qualities. They have a matte finish, look natural (kind of like wood), and feel soft yet textured to the touch. They’re not shiny or slick. When placed on a table, they don’t make a loud noise — instead, they land quietly and gently. Plus, they don’t have that cold, hard feel like plastic or metal. This isn’t your typical mass-produced material. Each piece has its own story, marked by subtle color variations, irregular pores, and the occasional small dent. Those imperfections? That’s exactly what makes cork charming and real.


Normally, when natural materials meet water, concerns pop up: “Will it mold?”, “Will it soften?”, “Will it start to smell?” Not with cork. It doesn’t soak up water like a sponge. It won’t rot, ferment, or trap musty odors. That’s why it stays fresh and worry-free, even in damp environments.


These days, words like “eco-friendly,” “organic,” and “natural” are everywhere — often more marketing than substance. Cork is different. Every piece comes from bark carefully harvested from cork oak trees without harming them. In fact, harvesting helps the tree absorb even more carbon dioxide from the air. So when you choose real cork, you’re doing more than buying a product — you’re backing forests and supporting their vital role in nature. It’s not just a trendy eco buzzword. Even if you’re picking up cork pieces just for fun or style, you’re making a positive impact on the planet.
