Ever find yourself cutting sheets to make them fit just right? Happens a lot — and let's be honest, the results aren’t always perfect. Rigid panels can't flex into small gaps or tricky spots. That’s why cork granules make sense. Simply pour them where needed — no cutting, no headaches. Lightweight, adaptable, and all-natural.

WHAT IS CORK GRANULES?

It’s natural cork ground into tiny particles. Super lightweight and flexible. Pour it anywhere panels can't reach — problem solved.

HOW CAN YOU USE CORK GRANULES?

Cork granules work great for all kinds of jobs:

Construction: Add to lightweight concrete, plaster, or use in foundations.
Insulation: Fill wall cavities to improve thermal efficiency.
Composite builds: Ideal core material for cabins and vehicle interiors.
Furniture making: Eco-friendly stuffing for ottomans, cushions, and seats.
Shoe manufacturing: Perfect for soles and shoe linings.
Gardening: Mix with soil to enhance structure and airflow.
Crafts and modeling: Use as gravel substitute for nativity scenes, dioramas, or stage props.
Spill absorption: Handy for soaking up oils and liquids.

WHAT’S THE DENSITY RANGE?

Density varies by grain size:

0.5 – 1.0 mm: Around 140–150 kg/m³.
1 – 2 mm: About 100–110 kg/m³.
2 – 3 mm: Roughly 120–130 kg/m³.
3 – 4 mm: Around 110–120 kg/m³.
4 – 5 mm: About 120–130 kg/m³.

IS CORK NATURAL AND ECO-FRIENDLY?

Absolutely. Cork comes from the bark of cork oak trees — harvested without harming the tree. 100% biodegradable and safe for the planet.

HOW IS CORK GRANULES MADE?

It all starts with cork oak bark. Stripped every 9–12 years, dried, cleaned, and ground into granules. Grain size varies from powder-fine to chunky.

DOES GRINDING CHANGE ITS PROPERTIES?

Nope. Granulated cork keeps its insulation, water resistance, and flexibility intact.

Granules just make it easier to use — pour, fill, and insulate spots where rolls and sheets fall short. Simple. Smart. Versatile.

IS CORK GOOD FOR INSULATION?

Definitely — cork is a natural insulator. Its air-filled cells make it excellent at blocking heat and noise.

Unlike synthetic materials, cork needs no chemicals. It's breathable, lightweight, and clean. Plus, it's eco-friendly, non-toxic, and healthy for your home.

ARE OTHER CORK GRANULE TYPES AVAILABLE?

Yes! We also offer:

Cork dust: Ultra-fine for specialty needs.
Cork nuggets: Larger bits for bulkier filling jobs.

WHAT'S THE BEST WAY TO STORE CORK GRANULES?

Keep them in a cool, dry space like a garage or basement. Avoid heat and direct sunlight. A sealed container will help them stay fresh and ready for use.

Most materials out there are either bulky and tough to work with or too flimsy to last. Granulated cork breaks the mold — it's lightweight, natural, and highly versatile. It truly shines in challenging spots like tight corners or uneven surfaces — anywhere you need a reliable material that fits seamlessly and performs well over time.

Black text WHY is it worth it? with cork on the right against a white background.

#1 ONE PRODUCT, COUNTLESS APPLICATIONS

Traditional insulation materials — polystyrene boards, mineral wool, or foam — often force you to work around them. You measure, trim, adjust... sometimes even rethink your entire plan. That's a serious time drain.

Granulated cork changes the game. It naturally adapts to any task, which is why builders and manufacturers love it. From lightweight concrete and thermal plasters to adhesives and foundations — cork is everywhere. When used to fill wall cavities, it significantly improves energy efficiency and makes your space more comfortable.

#2 EXCELLENT INSULATION WITHOUT THE EXTRA WEIGHT

Granulated cork boasts outstanding thermal and sound insulating properties. Its secret lies in its structure — millions of tiny air pockets that naturally block noise and stabilize temperatures. Unlike many fillers, cork is remarkably light, keeping your structure strong without adding unnecessary load.

Blending cork into concrete isn’t just eco-friendly — it actually enhances performance. These cork-based mixes retain heat better, minimize noise, and make handling much easier.

#3 100% NATURAL AND SUSTAINABLE

What you’re getting here is authentic natural cork. Most of it comes from Portugal, where cork harvesting follows deep-rooted traditions and strict quality controls.

This isn’t just green marketing — this is the real deal. The cork bark is carefully hand-stripped without harming the tree, which keeps growing and producing. Unlike many resources that need constant cultivation, cork flourishes on its own — naturally and sustainably.

#4 BUILT TO PERFORM FOR YEARS

Granulated cork isn’t just about insulation — it’s also incredibly durable. It repels moisture, meaning mold and mildew are kept at bay. And pests? They simply aren't interested. Cork doesn’t attract insects or rodents — even termites and ants leave it alone.

Besides being a great thermal and sound insulator, cork is also non-conductive, which makes it a smart option around electrical systems. On top of that, thanks to its chemical stability, cork stays reliable and effective for the long haul — unlike many other natural materials that break down with age.
